It is part of the lowpaymentfee.com platform, which offers a broad suite of data, analytics, AI, finance, and utility APIs — all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe endpoint accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers include an X-PAYMENT header with a signed USDC payment of up to 20,000 base units ($0.02, since USDC uses 6 decimals) on Base. No API keys, accounts, or rate limits are advertised — access is purely payment-gated. The payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout.\n\nDocumentation beyond the landing page is extremely sparse. The /docs, /pricing, /api, and /README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no example payloads available. The specific fields returned for stock history (e.g., OHLCV, date ranges, granularity) are unknown and must be inferred or discovered by making a paid request.","tags":[],"capabilities":["stock-history","historical-price-data","x402-payment","usdc-base","per-request-billing","no-api-key","json-response"],"categories":["finance","data"],"synonyms":["AMD stock history","stock price API","historical stock data","equity price feed","stock OHLCV","AMD share price","financial data API","x402 stock API"],"warnings":["No API documentation available — /docs, /pricing, /api, and /README all return only a wallet-connect prompt with no content.","No request or response schema is published; callers cannot know what fields to send or expect without trial-and-error.","Only the AMD ticker path is documented in this listing; availability of other tickers is unknown.","The platform lists many other endpoints on its landing page but provides no detailed docs for any of them."],"endpointUrl":"https://lowpaymentfee.com/api/v1/stocks/AMD/history","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/history","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation, and no examples.
