x402-payable account statements endpoint on Base, settling in USDC at $0.02/request.
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-request APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request and settled in USDC on the Base network.
The specific endpoint `/api/v1/accounts/90/statements` accepts POST requests and returns JSON. The x402 challenge advertises a maxAmountRequired of 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals), which equals $0.02 USD. Payment is made via the x402 "exact" scheme to the specified payTo address. No API keys or rate limits are advertised; access is granted purely through per-call micropayment.
Documentation is extremely sparse. The crawled docs, pricing, and API 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 endpoint is confirmed live (returns 402 with a valid x402 challenge), but the actual data returned after payment and the expected POST body are unknown.

Quality
The endpoint is confirmed live with a valid x402 challenge, but there is no documentation, no OpenAPI spec, no request/response examples, and no explanation of what 'accounts/90/statements' actually returns. The listing is effectively a stub with only pricing and liveness confirmed.
Warnings
- —No API documentation available — docs, pricing, and API pages all render only a wallet-connect prompt with no content.
- —No OpenAPI or schema definition found; request body format and response structure are completely unknown.
- —The endpoint path includes a hardcoded account ID (90); it is unclear whether other account IDs are supported or what data is returned.
- —The platform lists many diverse API categories (AI, finance, geocoding, etc.) all at the same price, which may indicate placeholder or demo endpoints rather than production services.
