It is part of a broader suite of pay-per-request APIs covering finance, AI/ML, data analytics, and infrastructure utilities. The endpoint uses the x402 payment protocol on the Base network, accepting USDC payments at $0.02 per request with no API keys, rate limits, or subscriptions required.\n\nThe endpoint is live and responds with a 402 Payment Required challenge when called without payment, as expected for x402 endpoints. It accepts POST requests and returns JSON. The specific stock price endpoint sits under the `/api/v1/stocks/{ticker}/price` path pattern, suggesting other ticker symbols may also be available, though only V is confirmed in this listing. The payment is settled on-chain via USDC on Base to the provider's wallet.\n\nDocumentation beyond the landing page is extremely sparse — the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI schema, no example request/response payloads, and no description of the response format. The endpoint's actual data source for stock prices is unknown.","tags":[],"capabilities":["stock-price-lookup","x402-payment","usdc-on-base","pay-per-request","json-response","no-api-key"],"categories":["finance","market-data"],"synonyms":["stock price API","equity price lookup","Visa stock price","ticker price endpoint","real-time stock data","x402 finance API","pay-per-call stock API"],"warnings":["No OpenAPI or schema documentation available — response format is unknown","Docs, API, pricing, and README pages all render only 'Connect wallet' with no content","Data source for stock prices is not disclosed","Only ticker V is confirmed; availability of other tickers is unverified"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/V/price","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/stocks/V/price","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base).
