Every endpoint is x402 v2 compliant: unpaid requests return HTTP 402 with a PAYMENT-REQUIRED challenge; callers sign an EIP-3009 USDC authorization and retry with a Payment-Signature header; settlement runs through Circle's Facilitator Service; every settled fill is stamped on-chain for public verification.","contact":{"name":"PayGate x402","url":"https://paygatex402.com","email":"lordginge82@gmail.com"},"x-guidance":"PayGate x402 is a pay-per-call API marketplace on Arc mainnet (eip155:5042). HOW TO PAY: 1) Call any endpoint below without auth — you get HTTP 402 with a PAYMENT-REQUIRED header containing a base64 x402 v2 challenge (accepts[]: scheme \"exact\", asset USDC 0x3600...0000, amount in 6-decimal base units, payTo wallet). 2) Sign an EIP-3009 TransferWithAuthorization (domain: name \"USDC\", version \"2\", chainId 5042) for exactly that amount. 3) Retry the same request with a Payment-Signature header carrying the base64-signed payload. 4) Circle's Facilitator verifies then settles on-chain; the paid response returns your data plus an X-Payment-Receipt header with the Arc tx hash. PRICES: fixed per endpoint, live values in each operation's x-payment-info.price (currency USDC) — the challenge amount always matches. CATEGORIES: market data (crypto-prices, crypto-ticker, order-book-depth, momentum-signal), RWA (centrifuge-rwa-*: pools, pool detail, share-class tokens), web extraction (extractr-arc: POST a URL, get clean text+summary), infrastructure (arc-rpc: read-only JSON-RPC proxy; arc-chain-status), and paid builder guides. RECOMMENDED FIRST CALL: GET /api/x402/crypto-prices?ids=ethereum&vs_currencies=usd ($0.001). TRIAL CREDIT: every new wallet can claim $1 of trial credit at paygatex402.com (sign a 0-value EIP-3009 voucher at /api/x402/trial-voucher) — sandbox-priced endpoints are free against it. ERRORS: 403 payment verification failed; 502 upstream failure after settlement is auto-refunded in ledger. Paid calls have no rate limit (payment is the throttle). Support: lordginge82@gmail.com.
