x402-gated account statements endpoint on Base, paid per-request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to account statement data behind an x402 paywall. The specific resource `/api/v1/accounts/125/statements` accepts POST requests and charges up to $0.02 per call in USDC on the Base network. Payment is handled via the x402 protocol — no API keys or subscriptions are needed; callers attach a cryptographic payment header and receive the response immediately.
The broader lowpaymentfee.com platform advertises a catalog of pay-per-request APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance/Web3 data (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request with no rate limits or minimum commitments. However, the specific endpoint being listed here — `/api/v1/accounts/125/statements` — is described only as "Premium API Access" and its request/response schema is not documented. The crawled docs, pricing, and README pages returned only a wallet-connect prompt with no additional technical detail.
Because there is no OpenAPI spec, no request/response schema, and no documentation beyond the landing page listing, the actual data returned by this endpoint is unclear. The account ID "125" appears hard-coded in the path, and it is unknown whether callers can substitute other account IDs or what fields the statement contains.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation beyond a landing page, and the purpose of this specific resource (account 125 statements) is unexplained. Effectively a stub listing.
Warnings
- —No OpenAPI or request/response schema available — callers cannot know what to send or what they will receive.
- —Documentation pages (/docs, /pricing, /README, /api) all returned only a wallet-connect prompt with no useful content.
- —The account ID '125' is hard-coded in the path; it is unclear if other account IDs are valid or what 'statements' contains.
- —The endpoint is labeled generically as 'Premium API Access' with no further description of the data it serves.
