x402-payable account statements endpoint on Base, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides account statement data behind an x402 paywall. The specific resource `/api/v1/accounts/50/statements` returns JSON account statements when called via POST with a valid X-PAYMENT header. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) at a cost of $0.02 per request (20,000 base units with 6 decimals).
The provider, lowpaymentfee.com, operates a broader catalog of x402-gated APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced uniformly at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access; callers authenticate purely through the x402 payment challenge. The x402 version is 1, using the "exact" payment scheme with a 300-second timeout.
Documentation is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no usage examples. The endpoint is confirmed live (returns HTTP 402 with a well-formed x402 challenge), but the actual data returned after payment is unknown. The endpoint path suggests financial account statements for account ID 50, but this cannot be verified from available material.

Quality
The endpoint is confirmed live via a well-formed x402 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no examples of what the endpoint actually returns. The specific resource path (accounts/50/statements) is opaque with no explanation of what account 50 represents or how to query other accounts.
Warnings
- —No OpenAPI or schema documentation available — request body and response format are completely unknown.
- —Docs, API, pricing, and README pages all render only 'Connect wallet' with no substantive content.
- —The endpoint path references a hardcoded account ID (50); it is unclear whether other account IDs are accessible or what data is returned.
- —No examples of successful responses are available; integration requires trial-and-error after payment.
