Which x402 API should my agent call? Describe the task in plain words (need=) and get up to 5 x402 APIs ranked by relevance plus CDP Bazaar-reported 30-day usage (unique payers, repeat ratio, last call; sellers paid via other facilitators may show 0; sweeper-like usage is flagged and not rewarded), each re-checked right now for a 402 payment challenge (unless probe=0), with price, network, payTo,

x402 preflight: before your agent signs a payment, fetch a paywalled URL's 402 and lint it. Parses v1 bodies and v2 PAYMENT-REQUIRED headers, then checks each accepts[] option: known network, canonical USDC, EIP-712 domain (extra.name/version) that a signature will verify against, EIP-55 payTo, zero/contract payTo, amount sanity, timeout, testnet, resource-host mismatch. Returns ok/warn/block per

aave-v3-arbitrum-usdc: USDC supply APR, time-weighted over 2026-09-23→2026-09-24, signed. Cheaper than the agent turns you'd burn finding the contracts, decoding ray-scaled rates, sampling the series, and time-weighting it — you trust the math, not us. Verify it offline — schema, every published figure recomputed, and the secp256k1 signature — with no API call and no trust in us.
