Israel Invoice Payment Gate and Counterparty Intelligence
One agent-native gate to check an Israeli supplier invoice before payment, with public-registry counterparty evidence.

For the current production posture, open leads, blockers, and next actions, see docs/PROJECT_STATUS.md. Partner entry: PARTNER_HANDOFF.md.
Bring your own trusted wallet: the free invoice result can prepare a private, validated request
for an existing x402 client, with a free supplier match and a 0.25 USDC proposed cap.
No seller wallet package is required. Downloading is not payment approval; the buyer's wallet must
enforce the live terms. Independent-wallet guide.
Start with the free invoice check,
download the validated invoice-request.json, and continue with the same invoice:
npx --yes https://israel-counterparty-intelligence.vercel.app/israel-company-verify-buyer-0.4.0.tgz --invoice-file invoice-request.json
Public agent metadata is available at /.well-known/x402, /llms.txt, and /README.md in the
production deployment. The Mainnet and Testnet payment resources use the same business logic but
remain separate payment routes so Test USDC can never unlock the Mainnet resource.
The same verification engine is also exposed as a stateless Remote Streamable HTTP MCP server:
POST /mcp - Base Mainnet, including a 0.25 USDC Israeli invoice payment gate plus company changes, verification, and vendor-risk tools.POST /mcp/testnet - Base Sepolia, 0.05 Test USDC per successful verify_company call.POST /mcp/pilot - invitation-only partner evaluation with a time-limited bearer token.- Company and payment-risk previews,
preview_agent_payment_trust, describe_service, and get_schema are free on both MCP endpoints.
Cheapest path to External Paid Call #1: company-changes at $0.01 USDC (omitted/{} body defaults company_number to public sample 514744887 for marketplace canaries) (before verify $0.05 / invoice-gate $0.25). Unpaid POST → HTTP 402 → pay with a buyer-controlled x402 wallet. See public/STATUS.md for the exact curl and MCP tool get_israeli_company_changes_paid.
This repository is a deliberately small MVP for External Paid Call #1. It resolves an Israeli
registered company, adds its public government-contract/support footprint, builds field-level
evidence, and returns a transparent heuristic risk signal. It is not a legal, credit, sanctions,
or investment service.
Current scope
POST /v1/verify - official company resolution and evidence.POST /v1/verify/mainnet - the same verification result, paid with real USDC on Base Mainnet.POST /v1/pilot/verify - invitation-only partner evaluation; never a public free route.POST /v1/government-footprint - public contracts and supports by exact company number.POST /v1/counterparty-risk - combined result and deterministic reason-coded score.POST /v1/payment-risk/mainnet - Mainnet pre-payment vendor triage with a PROCEED, REVIEW, or BLOCK result.POST /v1/invoice-gate/preview - free invoice arithmetic and allocation-applicability preview using date, amount, VAT component, and buyer-attested conditions; never authorization to pay.POST /v1/invoice-gate/mainnet - 0.25 USDC registry-backed Israeli invoice gate returning PAY, HOLD, or BLOCK.POST /v1/company-changes/mainnet - recent official company filing and status-change events for an exact company number, newest first, with source evidence.POST /v1/agent-payment-trust - free dry-run x402 pre-sign firewall with ALLOW, REVIEW, or DENY; it never signs or submits a payment.GET /health - health check.GET /openapi.json - machine-readable contract.- x402 v2 fixed-price protection and Bazaar metadata when
X402_ENABLED=true.
- Remote Streamable HTTP MCP with paid
verify_company plus free preview_company, preview_agent_payment_trust, describe_service, and get_schema.
Allocation applicability uses a strictly-greater-than amount threshold and also depends on a VAT component, an authorized-dealer buyer, and a buyer request; missing buyer context fails safely to HOLD. This service does not call or independently authenticate the Tax Authority; official allocation verification requires the buyer's own authorized dealer/representative connection. Buyer-supplied verification results are labeled BUYER_ATTESTED and are not independently authenticated. Not included: dashboards, accounts, subscriptions, PDF reports, broad scraping, bank-account
ownership verification, document forensics, UBO/PEP/sanctions certification, adverse-media
screening, creditworthiness, TASE enrichment, or a custom ML model.
Verified Payee Firewall MVP
preview_agent_payment_trust evaluates exact x402 terms before a buyer wallet signs. It resolves
the claimed Israeli company, fetches /.well-known/agent-payee.json from the service origin with
SSRF and redirect protections, validates the manifest and EVM signature, checks the declared
payment destination, verifies the payment resource origin and buyer mandate, and creates a stable
SHA-256 fingerprint of the payment contract.
ALLOW is fail-closed: it requires an active resolved company, a valid domain-fetched manifest,
an authorized payment destination, a matching resource origin, and a complete buyer mandate.
REVIEW and DENY must not be signed automatically. Level 1 and Level 2 assurance do not prove
legal ownership of the recipient wallet. The manifest specification is published at
/agent-payee-manifest-v0.1.md and its JSON Schema at
/.well-known/agent-payee-schema.json.
Production status: MAINNET LIVE - first external paid call confirmed. Public buyer-facing summary: public/STATUS.md (served at /STATUS.md). No internal Mainnet
payment is required for launch. The first genuine external Base Mainnet USDC payment is also the
first production end-to-end settlement and External Paid Call #1.
Public sources
The company adapters use the Ministry of Justice Companies Registrar open CKAN company dataset and
the Corporations Authority daily changes dataset on data.gov.il. The changes source covers up to
approximately one year; an empty result does not prove that no earlier change occurred. Official
request types are returned as facts and mapped to deterministic navigation categories, not risk
conclusions. The government-footprint adapter uses the public BudgetKey table API. Source URLs,
retrieval time, source record identifiers, and confidence are returned in evidence.
The service returns null and missing_data when data is unavailable. It does not convert a
government contract into a trust endorsement and does not add risk points merely because a source
is missing.
Local setup
Requirements: Node.js 20 or newer.
npm install
cp .env.example .env.local
npm run dev
Run all checks:
Example
curl -X POST http://localhost:3000/v1/verify \
-H 'content-type: application/json' \
-d '{"company_number":"514744887","language":"en"}'
Name lookup is also supported:
{
"company_name": "MONDAY.COM",
"city": "Tel Aviv",
"language": "en"
}
When several candidates are plausible, the API returns 409 AMBIGUOUS_ENTITY and candidates. It
never silently selects one. An invalid number returns 400; no reliable entity returns 422 for
the two enrichment endpoints.
x402 configuration
The implementation uses the official x402 v2 packages and Next.js withX402, so settlement occurs
only after a successful response. The default test setup is Base Sepolia through the public x402
test facilitator.
Required to enable payment:
X402_ENABLED=true
X402_PAY_TO=0xYourReceivingWallet
X402_NETWORK=eip155:84532
X402_ASSET=0x036CbD53842c5426634e7929541eC2318f3dCF7e
X402_FACILITATOR_URL=https://facilitator.payai.network
PUBLIC_BASE_URL=https://your-public-host.example
Prices are centralized in environment variables:
X402_VERIFY_PRICE=$0.10
X402_GOVERNMENT_PRICE=$0.35
X402_RISK_PRICE=$0.50
The independent Mainnet resource uses:
X402_MAINNET_ENABLED=true
X402_MAINNET_PAY_TO=0xYourReceivingWallet
X402_MAINNET_NETWORK=eip155:8453
X402_MAINNET_ASSET=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913

Without a payment signature, a protected endpoint returns 402 with PAYMENT-REQUIRED. The
challenge includes Bazaar input/output metadata. A compatible paid client must echo that extension
in its payment payload. Catalog inclusion happens only after a facilitator processes a conforming
paid payload and is ultimately controlled by that facilitator.
X402_MAINNET_FACILITATOR_PROVIDER=auto preserves the configured URL until both CDP credentials
are present. When they are added, Mainnet verification and settlement automatically switch to the
authenticated Coinbase CDP facilitator. The secret never appears in challenges, logs, or health
responses. Run npm run bazaar:check to validate all live paid endpoints against Coinbase Bazaar;
the same read-only check runs daily in GitHub Actions.
The Base Sepolia and Base Mainnet network identifiers and USDC assets are validated as distinct
configuration values. Price, asset, network, facilitator and payTo are server-owned and cannot be
overridden by request input.
MCP client setup
Production MCP URL:
https://israel-counterparty-intelligence.vercel.app/mcp
The endpoint implements Streamable HTTP and x402 v2. Standard MCP clients can initialize the
server, list tools, and call the free tools. preview_company returns identity/status plus exact
reusable arguments for the next paid action. A paid verify_company call returns a structured
PaymentRequired result until the client retries it with _meta["x402/payment"]; a successful
settlement is returned in _meta["x402/payment-response"]. Use an x402-aware MCP client such as
@x402/mcp for automatic signing and retry. No buyer account or API key is required.
The production PaymentRequired.resource.description includes the canonical buyer guide:
https://israel-counterparty-intelligence.vercel.app/x402-buyer-quickstart.md. It contains a
Streamable HTTP client example, explicit Base Mainnet/USDC requirements, per-tool spend guards,
and the expected payment/settlement metadata. A normal MCP client without an x402 wallet bridge can
discover and call the free tools but cannot complete verify_company automatically.
Minimal client configuration for Claude and other clients that accept remote HTTP MCP servers:
{
"mcpServers": {
"israel-business-intelligence": {
"type": "http",
"url": "https://israel-counterparty-intelligence.vercel.app/mcp"
}
}
}
LangChain uses the same URL with transport http; CrewAI and Google ADK use transport
streamable-http. Their standard MCP adapters can discover and call the free tools. Paid calls
require the x402 payment metadata round trip described above; no framework-specific SDK is needed.
An isolated, buyer-controlled supplier-onboarding composition is available in
examples/aerchain-adapter. It includes a strict Base
Mainnet payment policy, registry-to-vendor mapping, settlement receipt handling, fixtures, and
tests. It does not alter the production service or represent public-registry evidence as full KYB.
Partner pilot
Partners that cannot pay in USDC get the whole product through an invitation-only bearer key,
with payment waived and usage metered per partner for a monthly invoice in ₪ or $:
| Product | REST (POST) | MCP tool on /mcp/pilot |
|---|
| Invoice gate (PAY / HOLD / BLOCK) | /v1/pilot/invoice-gate | authorize_israeli_invoice_payment_paid |
| Company verification | /v1/pilot/verify | verify_israeli_company_paid (alias verify_company) |
| Vendor payment risk | /v1/pilot/payment-risk | assess_israeli_vendor_payment_risk_paid |
| Company changes | /v1/pilot/company-changes | get_israeli_company_changes_paid |
Contracts match the paid Mainnet routes; pilot responses add a pilot block and x-pilot-*
headers. Keys live in the PILOT_KEYS environment variable as a JSON array, one entry per partner
with its own SHA-256 digest, expiry, and call allowance; the raw key never enters the repository.
Each successful call emits a pilot_call event with the partner identifier and tool and no raw
token or raw IP address. With UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN set, usage is
also counted durably per partner (pilot-period and calendar-month hashes) and enforced against the
allowance; GET /v1/pilot/usage returns it to the partner, or to the operator for every partner.
Without Upstash the in-process counter is only a safety cap and the authoritative total is the
centralized count of successful pilot_call events. See the pilot runbook for
key issuance, activation, verification, metering, and revocation.
Smoke tests
Against a running unprotected service and the live public sources:
BASE_URL=http://localhost:3000 npm run smoke
Against a running x402-enabled service, without paying:
BASE_URL=http://localhost:3000 EXPECT_X402=true npm run smoke
The x402 smoke mode verifies HTTP 402, the payment header, protocol version 2, the exact configured
price, and Bazaar metadata. Base Sepolia already proves the complete settlement flow. Mainnet stays
live without an operator-funded self-payment and waits for a genuine external payer.
MCP discovery and free-tool smoke test:
MCP_URL=https://israel-counterparty-intelligence.vercel.app/mcp/testnet npm run smoke:mcp
The paid MCP smoke script is hard-restricted to /mcp/testnet and requires an isolated Base
Sepolia wallet file supplied outside the repository:
X402_TEST_WALLET_FILE=/secure/path/test-wallet.json npm run smoke:mcp:paid
Risk scoring v0.1.0
- Entity not active: +40.
- Registry law-violation flag: +25.
- Annual report older than two years: +10.
- 0-19: LOW, 20-49: MEDIUM, 50-100: HIGH.
- Ambiguous identity is not scored.
- Missing critical identity data blocks scoring; missing enrichment lowers confidence.
Every risk response includes reason_codes, explanation, confidence, scoring_version, and an
inference evidence record. The safe interpretation is: no material public warning flags were found
in the sources checked - never that a transaction is safe.
Reliability and privacy
- Typed adapters with Zod response validation.
- Abort timeouts and one bounded retry by default.
- Six-hour in-memory source cache.
- Per-instance in-memory rate limiting.
- JSON logs with request ID, timing, source calls, payment presence, confidence, error category, and
a shortened one-way client fingerprint.
- Only a successful settlement on the exact Base Mainnet route, official Base USDC contract,
configured amount and configured payTo can emit
external_paid_call. Testnet and the configured
internal test payers are excluded. The event is emitted by the post-settlement SDK hook and
includes network, asset, payer, amount, transaction hash, resource and optional discovery source.
- No user database and no raw IP logging in application code.
- No secrets in the repository.
- Pilot authentication compares a SHA-256 token digest in constant time; the raw credential stays
outside the repository.
In-memory cache and rate limiting are sufficient for the first paid-call experiment, not a
multi-region high-volume service. Add shared infrastructure only after real demand appears.
Deployment
Build first:
Then link and deploy from this directory:
vercel link
vercel deploy
vercel promote <validated-preview-url>
Configure runtime environment variables in Vercel rather than committing them. Keep x402 disabled
until the receiving wallet is correct. After enabling x402, redeploy and run the non-paying 402
smoke test. Do not manufacture a Mainnet settlement for activation or discovery.
External Paid Call #1
- Keep the public Mainnet endpoint and discovery metadata live.
- Wait for a payer that is not controlled by the operator.
- Require successful Base Mainnet settlement with real USDC and an HTTP 200 API response.
- Exclude Testnet, internal wallets, smoke tests, crawlers and directory probes.
- Emit
external_paid_call with network, payer, amount, transaction hash, resource and timestamp.
- Treat that same event as the first Mainnet end-to-end proof and External Paid Call #1.
Do not add features if no external paid call occurs after a reasonable discovery and outreach test.
Change the offer or stop.
