The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per call (20,000 base units with 6 decimals). No API keys or rate limits are required — callers simply attach an x402 payment header to each request.\n\nThe provider hosts a broader suite of APIs covering data analytics, AI/ML inference (sentiment, summarization, classification, embeddings), finance (price feeds, exchange rates, crypto quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation), all priced uniformly at $0.02 per request. However, this specific listing covers only the `/api/v1/stocks/AMD` endpoint.\n\nDocumentation is extremely sparse. The crawled docs, API, pricing, and README pages all rendered only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available. The endpoint is confirmed live — it returns a proper 402 challenge with x402 version 1 — but the exact request body format and response structure are unknown and must be discovered by the caller.","tags":[],"capabilities":["stock-quote","pay-per-request","x402-protocol","usdc-payment","base-network","no-api-key","json-response"],"categories":["finance","data"],"synonyms":["AMD stock price","stock data API","equity quote","stock market data","pay-per-call stock API","x402 stock endpoint","USDC micropayment API"],"warnings":["No OpenAPI or schema documentation available — request body format and response structure are unknown","All documentation pages (docs, API, pricing, README) render only 'Connect wallet' with no technical content","The specific stock data source, freshness, and coverage (real-time vs. delayed) are not disclosed","This endpoint covers only AMD; multi-ticker support is unconfirmed"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/AMD","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/AMD","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 402 challenge, confirming it exists and accepts payment.
