⚠️ Limitations

Provided source material includes no technical MCP transport details, tool names, or usage examples beyond the pricing and marketplace description.

Captured live from the server via tools/list.

browse_apis

Search the Proxygate marketplace for APIs an agent can buy. Optional free-text query (semantic + keyword search, same as the public catalog), category filter, and result limit. Returns each API with its listing id, name, service slug (for call_api), category, buyer price per request (in micro-USDC), listing type, trust/rating hints, and a capped endpoint preview (endpoint_count = full total). No authentication required.

category	string	optional
limit	integer	optional

    }
  },
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "additionalProperties": false
}

get_pricing

Get per-service pricing for Proxygate APIs. Optional single-service filter (exact service slug — take it from browse_apis). Returns the per-request USDC price plus per-input/output token USDC prices (null for per-request services). No authentication required.

  "additionalProperties": false
}

check_balance

Get the authenticated wallet's Proxygate balance breakdown: total balance, available (spendable now), and pending settlement, all in micro-USDC. Top up via the x402 rail (GET /v1/x402/topup). Requires authentication.

Parameters

No parameters.

get_usage

List the authenticated wallet's recent Proxygate API requests (newest first), with service, path, HTTP status, cost in micro-USDC, and timestamp. Cursor-paginated. Requires authentication.

Parameters2

limit	integer	optional
cursor	string	optional

Raw schema

  "type": "object",
  "properties": {
    "limit": {
      "type": "integer",

      "type": "string"
    }
  },
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "additionalProperties": false
}

rate_seller

Rate a seller after buying from one of their listings. Give the listing_id and a thumbs verdict (score: true = positive). Proxygate rates the wallet's most recent successful request to that listing (within the last 24h). Rating only, no payment. Requires authentication.

Parameters2

listing_id	string	required
score	boolean	required

Raw schema

{
  "type": "object",
  "properties": {
    "listing_id": {
      "type": "string"

    "score": {

    }
  },
  "required": [
    "listing_id",
    "score"
  ],
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "additionalProperties": false
}

call_api

Execute a billed API call through Proxygate, end-to-end. Give a listing_id from browse_apis, the endpoint path, and the HTTP method; the service slug is optional (derived from the listing). Optional query/headers/body pass through; set header x-proxygate-shield to off/monitor/strict to control response scanning. Proxygate reserves balance, handles upstream authentication for you, forwards the request, and charges your wallet. Returns the upstream status, headers, and body plus the amount charged (cost_micro_usdc), a signed receipt, and a request_id. Spends from your balance — requires authentication with the mcp:trade (or proxy) scope.

Parameters7

service	string	optional	Service slug to call (the proxy path segment). Optional when listing_id is given; the gateway derives it from the listing.
path	string	required	Upstream path with optional inline query string, e.g. "api/v3/simple/price?ids=bitcoin".
method	string	required	HTTP method for the proxied request. Defaults to GET.
query	object	optional	Query parameters as key/value pairs, an alternative to inlining them in path.
headers	object	optional	Allowlisted request headers. Authorization, wallet, and proxy-internal headers are dropped by the gateway.
body	any	optional	Passthrough request body, upstream-defined JSON value.
listing_id	string	optional	Listing id of the seller listing to bill, from browse_apis. Required in practice: calls without it are rejected with guidance (the field stays schema-optional for contract compatibility). service may be omitted when listing_id is given.

describe_endpoint

Inspect one endpoint of a listing before spending: parameters (name, location, required, type), request body schema, and response schemas, resolved one $ref level from the listing's uploaded docs. Give the listing_id from browse_apis plus the endpoint method and path (for GraphQL listings: the operation name as path). No authentication required.

Parameters3

listing_id	string	required	Listing UUID from browse_apis.
method	string	required	HTTP method of the endpoint, exactly as returned by browse_apis. Ignored for GraphQL listings.
path	string	required	Endpoint path exactly as returned by browse_apis. For GraphQL listings: the operation name.

Proxygate Agent Skills

The agentic commerce marketplace for AI agents. Sellers list unused API capacity. AI agents buy access through a transparent proxy. Keys never leave the server. Payments in USDC on Solana.

Skills for Claude Code, Codex CLI, and other AI coding assistants.

How it works

code

  Seller                    Proxygate                    Agent
  ┌──────┐                 ┌──────────┐                 ┌──────┐
  │ API  │◄── key stays ──►│ Gateway  │◄── USDC pay ──►│ Bot  │
  │ Key  │    on server     │          │    per call     │      │
  └──────┘                 └──────────┘                 └──────┘
     │                          │                          │
     │  1. List capacity        │  3. Proxy request        │
     │  2. Set price            │  4. Inject key           │
     │                          │  5. Deduct credits       │
     │                          │  6. Settle USDC          │

Sellers list APIs they have access to. Agents pay per call with USDC. The gateway injects the seller's key server-side — the agent never sees it. Settlement happens on Solana.

Skills

Skill	What it does
`proxygate`	Router — automatically picks the right sub-skill
`pg-setup`	Install CLI, authenticate (API key, WalletConnect, or keypair)
`pg-buy`	Browse APIs, deposit USDC, proxy requests, stream responses
`pg-sell`	Create listings, manage keys, expose services via tunnel
`pg-status`	Check balance, usage, listings, earnings
`pg-update`	Update CLI and SDK to latest version

Install

Via CLI (recommended)

bash

npm install -g @proxygate/cli
proxygate skills install

Via Skills CLI

bash

npx skills add proxygate-official/proxygate

Manual

bash

git clone https://github.com/proxygate-official/proxygate.git /tmp/pg-skills
cp -r /tmp/pg-skills/proxygate /tmp/pg-skills/pg-* ~/.claude/skills/

Quick start

bash

# 1. Authenticate
proxygate login                              # interactive — API key or wallet

# 2. Find an API
proxygate search weather

# 3. Call it
proxygate proxy weather-api /v1/forecast \
  -d '{"latitude":52.37,"longitude":4.90}'

# cost: $0.0012 | request: 905b1a53

Or just tell your AI assistant:

"Search for a weather API on Proxygate and get the forecast for Amsterdam"

The skills handle the rest.

Auth modes

Mode	Best for	On-chain?
API key	Agents, scripts, quick start	No
WalletConnect	Mobile wallet users (Phantom, Solflare)	No
Keypair	Full access — deposit, withdraw, settle	Yes

Start with an API key — no wallet needed. Get one at app.proxygate.ai/wallets.
