x402-payable account statements endpoint on Base, $0.02/request in USDC.
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, settled in USDC on the Base network.
The specific endpoint `/api/v1/accounts/169/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 to the specified payTo address, with a 300-second timeout. No API keys or rate limits are advertised; access is gated purely by the per-request micropayment.
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 live (returns a valid 402 challenge), but without documentation it is unclear what request body the POST expects or what the returned statement data looks like. The platform appears to be a demonstration or early-stage service for x402-based API monetization.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no documentation, no OpenAPI spec, no request/response schema, and no examples. The docs pages are empty. The purpose of the specific /accounts/169/statements path is unclear and may be a demo or placeholder.
Warnings
- —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet'
- —No OpenAPI or request/response schema provided; request body format is unknown
- —The endpoint path includes a hardcoded account ID (169), suggesting it may be a demo or single-purpose resource
- —Platform appears early-stage; reliability and data quality are unverifiable
