What it does

This endpoint at lowpaymentfee.com provides access to a database snapshot for June 2025 (`/api/v1/database/snapshots/2025-06`). It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs — all payable per-request via the x402 protocol on the Base network using USDC.

The endpoint accepts POST requests and returns JSON. Payment is handled inline: callers attach an X-PAYMENT header satisfying the x402 challenge. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD. The platform advertises a flat $0.02/request price across all endpoints, with no API keys, no rate limits, and no minimum commitments.

Documentation beyond the landing page is extremely thin — the /docs, /pricing, /api, and /README pages all returned 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 actual contents and structure of the "database snapshot" are unknown. The endpoint is confirmed live (returns a proper 402 challenge), but without documentation it is difficult to know what data is returned or what POST body (if any) is expected.

Quality

0.30/ 1.00

The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no documentation of request/response schemas, and no examples. The purpose of the 'database snapshot' is entirely opaque. Score reflects a confirmed-live endpoint with almost no usable documentation.

Warnings

  • —No OpenAPI or schema documentation available — request body and response structure are unknown
  • —All documentation pages (/docs, /pricing, /api, /README) returned only 'Connect wallet' with no content
  • —The nature and contents of the 'database snapshot' are not described anywhere in the crawled material
  • —This endpoint is date-specific (2025-06); it is unclear whether it is regularly updated or a one-time resource
