What it does

This endpoint provides historical stock price data for Nike (NKE) through the x402 payment protocol. It is part of a broader API platform at lowpaymentfee.com that offers data & analytics, AI/ML, finance, and infrastructure endpoints, all priced at $0.02 per request with no API keys, no rate limits, and no commitments required.

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

Note that while the endpoint is live and returns a valid 402 challenge, the crawled documentation pages (docs, pricing, API, README) all rendered only a "Connect wallet" prompt with no additional technical documentation. The exact request body schema and response format for the stock history endpoint are not documented in the available material, so the input/output structure must be inferred. The URL pattern suggests ticker-specific historical data (NKE in this case), but it is unclear whether date ranges, intervals, or other parameters are supported.

Quality

0.40/ 1.00

The endpoint is live and returns a valid x402 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no documentation for the request body schema, response format, or supported parameters. All doc/pricing/README pages rendered only 'Connect wallet' with no content. The listing is largely inferred from the URL pattern and homepage description.

Warnings

  • —No documentation available — docs, pricing, API, and README pages all show only 'Connect wallet'
  • —Request body schema and response format are unknown; example_request_json is speculative
  • —This endpoint is specific to NKE (Nike); it is unclear if other tickers are available at similar paths
  • —The outputSchema in the x402 challenge only specifies HTTP POST with discoverable=true, no field-level schema
