It is hosted on lowpaymentfee.com, a platform that offers a broad catalog of pay-per-request APIs spanning finance, AI/ML, data analytics, and utility services. Each call costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required.\n\nThe specific endpoint `/api/v1/market/quote/TSLA` accepts HTTP POST requests and returns JSON. Payment is handled inline via the x402 `X-PAYMENT` header using the \"exact\" scheme, settling to a designated address on Base. The USDC asset contract is `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` (the canonical USDC on Base, 6 decimals). The maximum amount required per call is 20,000 base units, which equals $0.02.\n\nNo OpenAPI schema, detailed documentation, or example responses were found in the crawl. The docs, pricing, and API pages all rendered only a \"Connect wallet\" prompt with no additional content. As a result, the exact shape of the response (fields like price, volume, timestamp, etc.) is unknown and must be inferred from the endpoint name. The endpoint is confirmed live — it returns a well-formed 402 challenge with x402 version 1.","tags":[],"capabilities":["stock-quote","market-data","x402-payment","usdc-settlement","base-network","pay-per-request","no-api-key"],"categories":["finance","market-data"],"synonyms":["TSLA stock price","Tesla quote API","real-time stock quote","equity market data","stock ticker API","pay-per-call finance API"],"warnings":["No OpenAPI or JSON schema available — response shape is unknown","Documentation pages (/docs, /pricing, /api, /README) all render only 'Connect wallet' with no useful content","The endpoint path suggests TSLA-specific data but no confirmation of what fields are returned","This endpoint is listed under 'Premium API Access' generically; actual data source and freshness are unverified"],"endpointUrl":"https://lowpaymentfee.com/api/v1/market/quote/TSLA","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/market/quote/TSLA","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.400","qualityRationale":"The endpoint is confirmed live with a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base).
