Check who your agent is about to pay over x402: real service, relayer, treasury, or buyer.

Verify payment recipient identity to distinguish between legitimate services, relayers, treasuries, and buyers.

Captured live from the server via tools/list.

check_counterparty

Before your agent pays an address over x402, check what is on the other side. Returns a plain verdict: a real service, a buyer, a relayer in the middle, or a treasury just moving funds, plus whether it is safe to pay. Free. For the full scored profile, the paid HTTP endpoint is $0.90. By Crest Deployment Systems.

Parameters (1)

addressstringrequired
the Base/EVM address your agent is about to pay (0x + 40 hex)

onchain_profile

Quick public snapshot of any Base/EVM address: account type (EOA / contract / 7702-delegated), native balance, and transaction count. Free coverage check.

Parameters (1)

addressstringrequired
Base/EVM address (0x + 40 hex)

pm_counterparty

Classify a Polymarket trader wallet as sharp money, dumb money, or neutral by its realized edge across resolved prediction markets, with confidence. Know who is on the other side of a prediction-market trade before your agent acts. Free; the deeper read is a $0.02 x402 HTTP call. Read-only, not betting advice. By Crest Deployment Systems.

Parameters (1)

addressstringrequired
Polymarket trader wallet (0x + 40 hex)

agent_preflight

Call BEFORE your agent transfers, trades, or settles to a wallet. Returns risk_level (low/medium/high/unknown) and reason codes from Crest counterparty intelligence, so your agent skips relayers, treasuries, and dead ends. Free; the full gate (changed-since cursor + ttl for cheap per-action re-checks) is a $0.02 x402 call. Read-only, not financial advice. By Crest Deployment Systems.

Parameters (1)

addressstringrequired
wallet your agent is about to interact with (0x + 40 hex)

agent_credit

Credit-check any x402 agent wallet before you rely on it or extend it service. Returns economic_class (funded/active/low/drained/unknown), live USDC balance, and a creditworthiness verdict, so you know if a counterparty will pay or is about to drain to zero. Free; full read (runway, observed burn) is a $0.05 x402 call. Read-only, not financial advice. By Crest Deployment Systems.

Parameters (1)

addressstringrequired
x402 agent wallet to credit-check (0x + 40 hex)

token_risk

Call this before your agent buys, swaps, or LPs into a Base token, to check if it is a rug, honeypot, or scam. Scans the contract for dangerous powers (mint new supply, blacklist wallets, pause transfers, upgrade the code) AND checks who controls those powers, scored on the Crest settlement graph: ownership renounced, an established issuer, a multisig, or an anonymous drained wallet. The same powers are safe under a trusted controller and a rug under an anonymous one. Example: token_risk(0x4ed4e862860bed51a9570b96d89af5e1b0efefed) -> { risk_level: "low", attack_surface: 20, controller_trust: 0.65 }. Free; the full report is a $0.05 x402 call. Read-only, not financial advice. By Crest Deployment Systems.

Parameters (1)

addressstringrequired
Base ERC-20 token contract address (0x + 40 hex)

crest_score

Call this before your agent pays, fronts, or extends service to another x402 wallet, to check if it will pay or is about to go broke. Two axes: solvency (will it stay funded) and liveness (will it keep paying), combined into one Crest Score with a band and a decision (ok_to_extend / monitor_or_prepay / prepay_only). Example: crest_score(0xe4a961cf1ee5b305561e38c69ed9dbd058ff036e) -> { crest_score: 89, band: "A", decision: "ok_to_extend" }. Built on the Crest settlement graph + live on-chain balance. Free; the full report (runway, monitoring cursor, change detection) is a $0.05 x402 call. Read-only, not financial advice. By Crest Deployment Systems.

Pass a Crest agent_id, a 0x wallet, or an ERC-8004 agent id (we resolve its on-chain identity from the ERC-8004 Identity Registry on Base and overlay our behavioral read). Read-only, not financial advice.
