What it does

This endpoint at lowpaymentfee.com provides access to a database snapshot dated 2023-01, served behind an x402 paywall on the Base network. The endpoint accepts POST requests and returns JSON data. Payment is settled in USDC (USD Coin) on Base, with a per-request cost of $0.02 (20,000 base units at 6 decimals).

The broader lowpaymentfee.com platform offers a suite of pay-per-call APIs spanning data & analytics (metrics, reports, data export, insights), AI & machine learning (sentiment analysis, text summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments required. Payments are handled via the x402 protocol on the Base L2 network.

The specific endpoint being listed here (`/api/v1/database/snapshots/2023-01`) appears to serve a historical database snapshot from January 2023. Documentation beyond the landing page is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of what data the snapshot contains or what fields the POST body expects.

Quality

0.30/ 1.00

The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, and no documentation describing what data the snapshot contains or what POST body fields are expected. The docs/pricing/README pages are all blank beyond a wallet connect prompt.

Warnings

  • No OpenAPI or schema documentation available — request and response formats are unknown
  • All documentation pages (docs, API, pricing, README) render only 'Connect wallet' with no technical content
  • The snapshot is dated 2023-01 — data may be stale or of unknown provenance
  • No description of what the database snapshot actually contains
