x402-gated account statements endpoint on Base, paid 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/170/statements`. It is part of a broader platform (lowpaymentfee.com) that offers a variety of x402-protocol pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services.
The specific endpoint probed returns a 402 challenge requesting payment of up to 20,000 base units of USDC on the Base network. Since USDC uses 6 decimals, this translates to $0.02 per request, consistent with the site's advertised flat pricing of $0.02/request across all endpoints. Payment is settled on-chain via the x402 "exact" scheme to address `0x1A2B...85F3`. The endpoint accepts POST, returns `application/json`, and has a payment timeout of 300 seconds.
The platform advertises no API keys, no rate limits, and instant access. However, documentation 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 account statements endpoint actually returns or what parameters it accepts. The endpoint path suggests it retrieves financial statements for a specific account (ID 170), but the actual data model is unknown.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing. However, there is no OpenAPI schema, no documentation of request parameters or response format, and the docs/pricing/README pages are all empty beyond a wallet-connect prompt. The purpose of this specific endpoint (account 170 statements) is unclear and undocumented.
Warnings
- —No API documentation available — docs, pricing, and README pages all show only 'Connect wallet' with no content.
- —No request or response schema provided; it is unknown what parameters the POST body should contain or what the response looks like.
- —The endpoint path references a specific account ID (170), and it is unclear whether other account IDs are accessible or what 'statements' contain.
- —The broader platform lists many endpoints (AI, finance, utilities) all at $0.02, but none have documented schemas or examples.
