GM (General Motors) earnings data via x402 micropayment on Base network for $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides earnings data for GM (General Motors) as part of a broader Finance & Web3 API suite. It is accessed via the x402 payment protocol, settling in USDC on the Base network. Each request costs $0.02 (20,000 base units of USDC with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The provider offers a wide catalog of pay-per-call endpoints spanning data analytics, AI/ML inference, finance/crypto market data, and utility services, all at a uniform $0.02 per request. This specific endpoint lives under the finance category and is discoverable via HTTP POST. The x402 challenge was successfully captured, confirming the endpoint is live.
Documentation is extremely sparse. The crawled /docs, /api, /pricing, and /README pages all returned only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The exact request body format and response structure for the GM earnings endpoint are unknown and must be discovered experimentally.
