x402-gated account statements endpoint on Base, pay-per-request with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to account statement data behind an x402 paywall. The specific resource `/api/v1/accounts/124/statements` accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with a maximum cost of $0.02 per request (20,000 base units at 6 decimals).
The broader lowpaymentfee.com platform advertises a wide catalog of x402-gated APIs spanning data & analytics, AI/ML (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation) — all priced at $0.02 per request. The platform emphasizes no API keys, no rate limits, and instant access via the x402 payment protocol.
Documentation is extremely sparse. The docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the statements endpoint expects or returns. The endpoint is confirmed live (402 challenge captured), but the actual functionality and data model remain unclear.

Quality
The endpoint is live and returns a valid x402 challenge, but there is zero documentation on request/response schemas, no OpenAPI spec, and the docs pages are empty stubs. The actual functionality of the 'statements' endpoint is unverifiable beyond its existence.
Warnings
- —No API documentation available — docs, pricing, and README pages all show only 'Connect wallet' with no content
- —No OpenAPI or request/response schema provided; input and output formats are unknown
- —The specific endpoint path includes a hardcoded account ID (124), suggesting it may be a demo or placeholder
- —Cannot verify what data the endpoint actually returns without making a paid request
