What it does

This endpoint at lowpaymentfee.com returns Tezos (XTZ) wallet balance data, gated behind an x402 payment challenge. Each request costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no sign-up required. The caller simply includes an X-PAYMENT header with a valid x402 payment proof to access the response.

The endpoint is part of a broader suite of pay-per-call APIs offered by lowpaymentfee.com spanning data analytics, AI/ML inference, finance/Web3 data, and utility services, all priced uniformly at $0.02 per request. The specific endpoint `/api/v1/wallet/XTZ/balance` falls under the Finance & Web3 category and is designed to return balance information for a given Tezos address.

Documentation on the site 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 request/response schema documentation, and no usage examples available from the provider. The x402 challenge confirms the endpoint is live and accepting POST requests, settling payments to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using USDC (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base.

Quality

The x402 challenge is live and confirms pricing and payment details, but there is zero documentation on request/response schemas, no OpenAPI spec, and the docs pages are empty stubs. The request and response examples are inferred, not sourced.

Warnings

  • —No OpenAPI or schema documentation available from the provider
  • —Docs, pricing, and API pages all render only 'Connect wallet' with no technical content
  • —Request body format and response schema are entirely inferred — no examples from provider
  • —The broader site lists many API categories but it is unclear how mature or functional each endpoint is
