Per-call stock data for ticker PLD via x402 micropayment on Base, $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides stock data for the ticker PLD (Prologis, Inc.) through an x402-compatible micropayment gateway settled in USDC on the Base network. Each request costs $0.02 (20,000 base units of USDC with 6 decimals). The endpoint accepts POST requests and returns JSON. No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The provider operates a broader platform offering dozens of endpoints across categories including data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced uniformly at $0.02 per request. The specific endpoint probed here (`/api/v1/stocks/PLD`) is not listed on the provider's landing page among the advertised APIs, but it is live and returns a valid 402 challenge. This suggests the stocks API may be an unlisted or less-promoted part of the catalog.
Documentation is extremely sparse. The docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no example request/response payloads, and no description of the response format beyond the stated MIME type of application/json. Callers should expect stock-related JSON data for PLD but the exact fields are unknown.

Quality
