x402-payable account statements endpoint on Base, settling in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides account statement data behind an x402 paywall. It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request and settled in USDC on the Base network.
The specific endpoint `/api/v1/accounts/185/statements` accepts POST requests and returns JSON. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is made via the x402 exact scheme with no API keys or rate limits required — callers simply attach the X-PAYMENT header with a valid payment proof.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the statements endpoint accepts or returns. The endpoint is confirmed live (402 challenge captured), but the actual data it serves and its input parameters are unknown.

Quality
The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and all documentation pages returned only a wallet-connect stub. The purpose of the specific /accounts/185/statements path is unclear — it may be a demo or placeholder account. This is effectively a stub listing.
Warnings
- —No API documentation available — all doc pages return only a 'Connect wallet' prompt
- —No OpenAPI or request/response schema provided; input parameters and response format are unknown
- —The endpoint path references a specific account ID (185), which may be a demo or placeholder
- —The platform lists many API categories but none have documented schemas or examples
