What it does

This endpoint provides historical stock price data for the ticker KO (Coca-Cola) through the x402 payment protocol. It is part of a broader API platform at lowpaymentfee.com that offers data & analytics, AI/ML inference, finance, crypto, and utility endpoints — all priced at $0.02 per request with no API keys, no rate limits, and no commitments.

The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The x402 challenge advertises a maxAmountRequired of 20,000 base units, which at 6 decimals equals $0.02 USD per call. The payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a timeout of 300 seconds.

Documentation is extremely sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what parameters the endpoint accepts or what fields the response contains. The endpoint is confirmed live (returns 402 challenge), but the actual data format and query parameters must be discovered experimentally.

Quality

0.35/ 1.00

The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and all documentation pages are empty beyond a wallet-connect prompt. The actual request parameters and response format are completely unknown.

Warnings

  • —No documentation available — /docs, /api, /pricing, and /README pages all show only 'Connect wallet' with no content
  • —No OpenAPI or schema describing request parameters or response fields
  • —Response format and accepted query parameters must be discovered experimentally
  • —Only the /stocks/KO/history path is referenced in this listing; the provider site lists many other endpoints but none are documented either
