Historical stock price data for BKNG (Booking Holdings) via x402 micropayment on Base.
What it does
This endpoint provides historical stock price data for Booking Holdings (ticker: BKNG) through the x402 payment protocol. It is part of a broader API platform at lowpaymentfee.com that offers data & analytics, AI/ML inference, finance, crypto, and utility endpoints—all gated behind per-request x402 micropayments settled in USDC on the Base network.
The endpoint accepts POST requests and returns JSON. Each call costs a maximum of $0.02 (20,000 base units of USDC with 6 decimals) paid via the x402 X-PAYMENT header. No API keys, accounts, or rate limits are required; callers simply attach a valid x402 payment to each request. The payment is sent to address 0x1A2B…85F3 on Base using the USDC contract at 0x8335…2913.
Documentation 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 spec, no request/response schema, and no example payloads available from the crawl. The exact request body format and the shape of the historical price response are unknown and must be discovered experimentally.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02/request in USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation, and no example payloads. The docs pages all render only a wallet-connect prompt. This is effectively a stub listing with minimal verifiable detail.
Warnings

- —All documentation pages (/docs, /api, /pricing, /README) return only a 'Connect wallet' prompt with no technical content.
- —The specific data source, coverage period, and granularity of the stock history are undocumented.
- —Endpoint description is generic ('Premium API Access') and does not describe the actual data returned.
