Historical stock price data for AMD via x402 micropayment on Base, $0.02/request.
What it does
This endpoint provides historical stock price data for AMD (Advanced Micro Devices) through an x402-protocol pay-per-request model. 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.
The 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.
Documentation 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.

Quality

Warnings

- —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.
