What it does

This endpoint provides historical stock price data for the ticker symbol MO (Altria Group) through the lowpaymentfee.com platform. It is an x402-enabled API that accepts POST requests and returns JSON responses. Payment is settled in USDC on the Base network at $0.02 per request (20,000 base units of USDC with 6 decimals).

The lowpaymentfee.com platform hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments. This specific endpoint sits under the finance category and serves stock history data. The x402 challenge was confirmed live, returning a proper 402 Payment Required response with an accepts block specifying the USDC asset contract on Base.

Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all rendered only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the historical data includes (e.g., OHLCV, date ranges, intervals). Prospective consumers should expect to experiment with the endpoint to discover its input parameters and output format.

Quality

0.35/ 1.00

The endpoint is confirmed live via a valid 402 x402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and no documentation beyond a wallet-connect prompt. The request body format and response structure are entirely unknown, making this effectively a stub listing.

Warnings

  • —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet'
  • —No OpenAPI or JSON schema for request or response
  • —Request body parameters (date range, interval, etc.) are unknown
  • —Response format and fields are unknown — no examples exist in crawled material
  • —This is one endpoint in a large catalog; quality and data sourcing are unverified
