What it does

This endpoint at lowpaymentfee.com provides access to a database snapshot dated 2023-08 via the x402 payment protocol. It is one of many endpoints offered by the lowpaymentfee.com platform, which hosts a variety of data, analytics, AI/ML, finance, and utility APIs — all priced at $0.02 per request and settled in USDC on the Base network.

The specific endpoint `/api/v1/database/snapshots/2023-08` accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers must include an `X-PAYMENT` header with a valid payment proof. The cost per call is 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. No API keys, rate limits, or upfront commitments are required — each request is individually paid.

Documentation beyond the landing page is sparse. The docs, API, pricing, and README pages all resolve to a minimal "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The exact contents and structure of the 2023-08 database snapshot are not described anywhere in the crawled material, so consumers will need to experiment or contact the provider to understand the data format.

Quality

0.35/ 1.00

The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no OpenAPI spec, no request/response schema, and no description of what the database snapshot actually contains. Effectively a stub listing.

Warnings

  • No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no technical content.
  • The contents and schema of the 2023-08 database snapshot are completely undocumented.
  • No OpenAPI specification or example request/response payloads are provided.
  • The broader lowpaymentfee.com platform lists many endpoints but none have detailed docs; quality of all endpoints is uncertain.
