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 statements via a POST request to `/api/v1/accounts/31/statements`. It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs — all gated behind the x402 payment protocol on the Base network.
The endpoint returns a 402 Payment Required challenge requesting payment of up to 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals), which equals $0.02 per request. Payment is settled on-chain to `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`. The response MIME type is `application/json`. No API keys are required; access is granted immediately upon valid x402 payment. The platform advertises no rate limits and a flat $0.02/request pricing model across all its endpoints.
Documentation is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The specific data returned by the `/accounts/31/statements` endpoint (e.g., what kind of account, what statement fields) is not documented anywhere in the crawled material. The endpoint is live and responding with a valid x402 challenge.

Quality
The endpoint is live and returns a valid x402 challenge, but documentation is essentially nonexistent — no request/response schemas, no examples, no explanation of what 'accounts/31/statements' actually returns. The listing is effectively a stub with only pricing and protocol details inferrable from the challenge.
Warnings
- —No API documentation available — docs, pricing, API, and README pages all show only 'Connect wallet' with no content
- —No request or response schema documented; unclear what data the /accounts/31/statements endpoint returns
- —The endpoint path includes a hardcoded account ID (31), suggesting it may be a demo or single-tenant resource
- —No OpenAPI spec or ai-plugin manifest found
