Vibes-Coded Agent Tool API
Verification PAYMENT-READYpayment-ready until 2026-08-20
Pay-per-call reliability and intelligence APIs for AI agents on Solana USDC via x402: destructive-action, infra-target, tool-call-budget, agent-state, drift, retry-storm guards, action receipts, and 90+ more endpoints. HTTP 402, no signup.
Pay from $0.02 to $0.10 per request in USDC on Base / Solana, settled onchain via the x402 protocol, no signup, no API key needed.

Measured on the unpaid 402 handshake, not the paid call. A service can 402 correctly and still fail after payment.
compliance C (13/14): EIP-712 domain parameters present on every EVM entry
13 of 14 x402 conformance checks pass; failing: EIP-712 domain parameters present on every EVM entry. Full checklist below.
signability route not signable
At least one EVM route on this service returns its 402 without the EIP-712 domain parameters (extra.name and extra.version), so a standard x402 client cannot build the signature for that route.
Measured on the last 402 envelope captured from this service. It is a fact about the envelope, not a judgement on the service or its operator.
This is the only conformance check that caps the compliance grade, at C.

risk clean
No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.

Conservative undercount: only USDC settlements via facilitators we measure are counted. A measured floor, not an estimate.
Top buyer share is a concentration signal, not part of the ranking score.

] OVER TIME
All charts use the 30d selector; each series spans only the dates it has data for. Every series is also served as JSON at /api/v1/services/vibes-coded-agent-tool-api/price, /scores, /volume and /buyers. On-chain volume and distinct buyers are measured over the service's settlement address and are a conservative undercount (only settlements that reach a measured facilitator are counted). The on-chain series roll up hourly, so the latest day can be up to about an hour behind; distinct buyers are counted per payout address, so a service that settles to more than one address is an upper bound.
Median across 6 endpoints. Use the selector to isolate one.

Measured site and economics pillars from the assessment history, so the latest value shown elsewhere on this page reads as a point on a trend rather than a permanent state.
