What it does

This endpoint at lowpaymentfee.com provides stock data for the ticker "CB" (Coinbase Global, Inc.) through an x402-protocol pay-per-call API. Each request costs $0.02 in USDC on the Base network. The endpoint accepts POST requests and returns JSON.

The provider, lowpaymentfee.com, hosts a broad catalog of x402-gated endpoints spanning data analytics, AI/ML inference, finance, crypto, and utility services — all priced at $0.02 per call. The specific endpoint `/api/v1/stocks/CB` falls under the finance category and presumably returns stock price or quote data for the CB ticker. No API keys or rate limits are advertised; access is granted by attaching an x402 payment header with each request.

Documentation is extremely sparse. The crawled docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available. The endpoint is confirmed live (returns a proper 402 challenge), but the exact request body format and response structure are unknown. The x402 challenge specifies payment to address 0x1A2B...85F3 using USDC (0x8335...2913) on Base, with a max amount of 20000 base units (i.e., $0.02 given USDC's 6 decimals) and a 300-second timeout.

Quality

0.30/ 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 spec, no documented request/response schema, no examples, and the docs pages are empty. The actual data returned is entirely unknown, making this effectively a stub listing.

Warnings

  • —No OpenAPI or schema documentation available — request body format and response structure are unknown.
  • —Docs, pricing, and API pages all render only 'Connect wallet' with no technical content.
  • —The specific data returned for /api/v1/stocks/CB (real-time quote, historical data, etc.) is unverified.
  • —Provider hosts many diverse endpoints; quality and reliability of each is undocumented.
