It 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.\n\nThe specific endpoint `/api/v1/stocks/CVX` accepts HTTP POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach an `X-PAYMENT` header containing a signed USDC payment on Base (contract `0x8335…2913`). The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02. The payment is sent to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a 300-second timeout window.\n\nNo OpenAPI schema or detailed documentation was found beyond the landing page. The docs, pricing, and API pages all resolve to a minimal \"Connect wallet\" prompt, so the exact response shape for stock data is unknown. The endpoint is confirmed live — it returns a proper 402 challenge. However, the lack of documented request/response schemas and the absence of any sample data mean integrators will need to experiment or contact the provider to understand the payload format.","tags":[],"capabilities":["stock-data","x402-payment","usdc-settlement","base-network","pay-per-request","no-api-key","json-response"],"categories":["finance","data"],"synonyms":["stock quote API","CVX stock data","Chevron stock price","x402 stock endpoint","pay-per-call stock API","USDC micropayment API","Base network API"],"warnings":["No OpenAPI or response schema available — the exact stock data payload is undocumented.","Docs, pricing, and API pages all render only a 'Connect wallet' prompt with no useful content.","The /api/v1/stocks/CVX path is not listed on the landing page; only /api/v1/finance/prices is shown under Finance.
