Pay-per-call ATOM token data via x402 on Base, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides token data for ATOM (Cosmos) via a simple POST request, paid per-call using the x402 protocol. Payment is settled in USDC on the Base network at $0.02 per request (maxAmountRequired of 20,000 base units 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 hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 market data, and utility services, all priced uniformly at $0.02 per request. This specific endpoint falls under the Finance & Web3 category and likely returns token pricing or market data for ATOM, though the exact response schema is not documented. The x402 challenge confirms the endpoint is live and accepting payments to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base.
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 spec, no example request/response, and no description of what fields the ATOM token endpoint returns. Callers should expect a JSON response (mimeType is application/json) but will need to experiment to discover the exact payload structure.

Quality
The endpoint is confirmed live via a valid 402 challenge with clear pricing ($0.02 USDC on Base), but there is no OpenAPI spec, no documented request/response schema, and all documentation pages render only a wallet-connect prompt. The listing is essentially a stub with pricing info.
