Real-time XTZ (Tezos) token price via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint returns the current price of the XTZ (Tezos) token, accessible via the x402 payment protocol. It is part of a broader suite of pay-per-call APIs hosted at lowpaymentfee.com, covering data analytics, AI/ML inference, finance, crypto, and utility services. Each request costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required.
The x402 challenge confirms the endpoint is live and accepts payment via the "exact" scheme on Base, settling in USDC (contract 0x8335…2913) to the provider's address. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02. The endpoint accepts POST requests and returns application/json responses.
Documentation beyond the landing page is sparse — the /docs, /pricing, /api, and /README pages all resolve to a wallet-connect stub with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema for the XTZ price data. The endpoint appears functional based on the 402 challenge, but the lack of documentation limits confidence in the exact response format.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no documented request/response schema, and all documentation pages beyond the landing page are empty wallet-connect stubs. The actual response format for the XTZ price endpoint must be guessed.
Warnings
- —No OpenAPI or schema documentation available — response format is unknown
- —All doc/pricing/README pages return only a wallet-connect stub with no content
- —No example responses or field descriptions for the token price data
- —Provider hosts many diverse endpoints (AI, analytics, finance, utils) all at $0.02 — unclear if all are fully implemented or placeholders
