Walmart earnings data via x402 micropayment on Base, $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides financial earnings data for Walmart (ticker: WM) through a pay-per-call x402 protocol. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required; access is gated entirely by the x402 payment header.
The provider, lowpaymentfee.com, hosts a broad catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per call. This specific endpoint falls under the Finance & Web3 category. However, 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 earnings data fields returned. The exact request body format and response structure must be discovered experimentally.
The endpoint is confirmed live — it returns a well-formed x402 version 1 challenge with a 402 status code. The payment is of type "exact" (one-shot per call), with a 300-second timeout. Because there is no published schema or sample data, agents should treat this as a best-effort financial data source and verify output quality before relying on it in production workflows.
