Get the current stock price for SBUX (Starbucks) via x402 micropayment on Base.
What it does
This endpoint returns the current stock price for Starbucks (SBUX) through a pay-per-request x402 protocol call settled in USDC on the Base network. The endpoint 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 required.
The specific endpoint `/api/v1/stocks/SBUX/price` accepts POST requests and returns JSON. Payment is handled via the x402 protocol: callers attach an `X-PAYMENT` header containing a signed USDC payment of up to $0.02 (20,000 base units of USDC on Base, asset contract `0x8335...2913`). The payment is settled on-chain to address `0x1A2B...85F3` with a maximum timeout of 300 seconds.
The platform advertises zero friction access — no API keys or accounts needed, just a crypto wallet capable of signing x402 payments. Documentation pages exist at `/docs`, `/pricing`, and `/api` but currently show minimal content (only a "Connect wallet" prompt), so detailed request/response schemas are not available from the provider's own docs. The endpoint URL pattern suggests it may support other stock tickers by replacing `SBUX` in the path.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing and asset info. However, there is no OpenAPI schema, no documented request/response format, and the provider's docs pages are effectively empty ('Connect wallet' only). The actual response payload structure must be inferred.
Warnings
- —No request or response schema documented — actual JSON structure is unknown
- —Provider docs pages (/docs, /pricing, /api, /README) return only 'Connect wallet' with no substantive content
- —It is unclear whether the endpoint returns real-time market data or delayed/cached prices
- —The stock ticker endpoint pattern (replacing SBUX) is inferred but not confirmed for other tickers
