S&P Global (SPGI) earnings data via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint provides earnings data for S&P Global (ticker: SPGI) through the lowpaymentfee.com platform. It is part of a broader Finance & Web3 API suite that includes price feeds, exchange rates, crypto quotes, and gas estimates. The endpoint is accessed via HTTP POST and is gated by the x402 payment protocol, requiring a per-request micropayment of $0.02 in USDC on the Base network.
The platform advertises a simple pay-per-use model with no API keys, no rate limits, no minimums, and instant access. Payment is settled on-chain via the x402 "exact" scheme, meaning each request requires a one-time USDC payment to the specified wallet address. The x402 challenge was successfully captured, confirming the endpoint is live.
Documentation is extremely sparse — the docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no example request/response, and no description of the earnings data format or fields returned. The specific endpoint path includes the ticker symbol SPGI, suggesting the URL pattern may be parameterized for different stock tickers, but this is not confirmed by any documentation.

Quality
