Caterpillar (CAT) earnings data via pay-per-request x402 endpoint on Base network.
What it does
This endpoint at lowpaymentfee.com provides financial earnings data for CAT (likely Caterpillar Inc.) through the x402 payment protocol. Each request costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required. The endpoint accepts POST requests and returns JSON.
The provider, lowpaymentfee.com, operates a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced uniformly at $0.02 per request. This specific endpoint sits under the Finance & Web3 category. The x402 challenge was successfully captured, confirming the endpoint is live and accepting payment via USDC (contract 0x8335…2913) on Base.
Documentation is extremely sparse. The crawled docs, API, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the earnings response contains or what parameters the POST body accepts. The endpoint path suggests it returns earnings-related financial data for the ticker "CAT," but the exact schema and data coverage are unknown.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is zero documentation on request parameters, response schema, or data coverage. Docs pages return only wallet-connect prompts. Effectively a stub listing.
