Crypto token data for XTZ via x402 micropayment on Base — $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides token data for XTZ (Tezos) as part of a broader suite of pay-per-call APIs covering data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network at a flat rate of $0.02 per request (20,000 base units of USDC with 6 decimals). No API keys or accounts are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The specific endpoint `/api/v1/tokens/XTZ` appears to return JSON data related to the XTZ (Tezos) token, likely including price or market information, though the exact response schema is not documented. The platform advertises no rate limits and instant access. The x402 challenge confirms the endpoint is live, accepting POST requests, and paying to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using USDC (`0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) on Base.
Documentation is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no response schema, and no example responses available. The endpoint's exact output fields and data sources are unknown.
