x402-gated account statements endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to account statement data behind an x402 payment wall. The specific resource `/api/v1/accounts/123/statements` is labeled "Premium API Access" and accepts POST requests. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with a maximum amount of 20,000 base units, which equals $0.02 USD (USDC uses 6 decimals).
The provider lowpaymentfee.com hosts a broader catalog of x402-gated APIs spanning data & analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are advertised at $0.02 per request with no API keys, no rate limits, and no minimum commitments required.
Documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of what the account statements endpoint actually returns. The endpoint is confirmed live (402 challenge captured), but the lack of documentation makes it difficult to know what data to send or expect back.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no OpenAPI schema, no request/response examples, and no meaningful documentation beyond a wallet-connect prompt. The actual data returned by the statements endpoint is entirely unknown.
Warnings

- —No OpenAPI or input/output schema provided; request body format is unknown
- —The endpoint path includes a hardcoded account ID (123), unclear if this is parameterizable
- —No information on what account statement data is actually returned
