Stock market quote for ADI (Analog Devices) via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint provides a market quote for the ticker symbol ADI (Analog Devices, Inc.) through the lowpaymentfee.com platform. It is part of a broader suite of Finance & Web3 APIs offered by the provider, which includes price feeds, exchange rates, token quotes, and gas estimates, all accessible via the x402 payment protocol on the Base network.
The endpoint accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach a USDC payment on Base in the X-PAYMENT header. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD. There are no API keys, no rate limits, and no subscription commitments — each request is independently paid for at the time of the call.
The provider's landing page lists numerous API categories (data & analytics, AI/ML, finance, infrastructure) all at the same $0.02/request price point. However, documentation beyond the landing page is essentially empty (all doc/pricing/API pages just show "Connect wallet"), so the exact request parameters and response schema for this specific quote endpoint are unknown. The endpoint is confirmed live via a valid 402 challenge, but the lack of documentation means callers will need to experiment or contact the provider to understand the expected POST body and response format.

Quality
The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no documentation, no OpenAPI schema, no example request/response, and no description of what fields the quote returns. The docs, pricing, and API pages are all blank beyond a wallet-connect prompt. This is effectively a stub listing.

- —Request body schema and response schema are completely unknown
- —The specific data returned for a market quote (price, volume, timestamp, etc.) is not documented
