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/138/statements`. It is part of a broader platform offering dozens of x402-payable API endpoints 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 probed here (`/accounts/138/statements`) appears to be a financial or account-level statements resource. Payment is handled via the x402 protocol: callers receive a 402 challenge with payment details (pay-to address, USDC asset contract on Base, max amount 20,000 base units = $0.02), and must include an `X-PAYMENT` header with a valid payment proof to access the resource. No API keys, rate limits, or upfront commitments are required — access is purely pay-per-call.
Documentation on the site is extremely thin. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what the statements endpoint actually returns. The endpoint is confirmed live (402 challenge captured), but the lack of documentation makes it difficult to know what input the POST body expects or what shape the response takes.

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 return only a wallet-connect prompt. The specific purpose of the /accounts/138/statements endpoint is unclear, and the hardcoded account ID (138) raises questions about generalizability.
Warnings
- —No API documentation available — docs, pricing, API, and README pages all show only 'Connect wallet'
- —No OpenAPI or JSON schema describing request body or response format
- —The endpoint path contains a hardcoded account ID (138); unclear if other account IDs are supported or how they are obtained
- —The platform lists many endpoint categories (AI, analytics, finance, infrastructure) all at $0.02 — unclear if all are fully functional or placeholders
