Get the current stock price for CRM (Salesforce) via a pay-per-call x402 endpoint on Base.
What it does
This endpoint returns the current stock price for the ticker CRM (Salesforce) through a simple HTTP POST request, paid per call using the x402 protocol on the Base network. It is part of a broader suite of APIs offered by lowpaymentfee.com, which spans 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 commitments.
The endpoint accepts payment in USDC on Base (contract 0x8335…2913) with a maximum amount of 20,000 base units, which equals $0.02 (USDC uses 6 decimals). Payment is handled via the x402 exact scheme: callers include an X-PAYMENT header with a signed payment facilitator token, and the server returns the stock price data as application/json. The x402 challenge was confirmed live, returning a proper 402 response.
Documentation beyond the landing page is sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The endpoint path suggests it returns a price for the CRM ticker, but the exact response format must be discovered empirically.
