Database snapshot (2023-07) accessible via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides access to a database snapshot dated 2023-07 via the x402 payment protocol. The endpoint accepts POST requests and returns JSON data. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) with a maximum cost of $0.02 per request (20,000 base units at 6 decimals).
lowpaymentfee.com hosts a broader suite of pay-per-call APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments. This particular endpoint falls under the data category, serving a historical database snapshot from July 2023.
Documentation is extremely sparse. The crawled /docs, /api, /pricing, 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 description of what the snapshot data actually contains. Prospective callers should be aware that the exact structure and content of the returned data is unknown from public documentation alone.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is zero documentation on what the snapshot contains, no request/response schema, and all doc pages return only a wallet-connect prompt. This is effectively a stub listing.
Warnings
- —No documentation available — /docs, /api, /pricing, and /README all return only a 'Connect wallet' prompt with no content
- —No OpenAPI spec or request/response schema provided
- —Unknown data contents — the snapshot's structure, fields, and coverage are undocumented
- —Static historical snapshot (2023-07) — unclear if data is still relevant or maintained
