Monero (XMR) token data via x402 micropayment on Base network, $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides token data for Monero (XMR) as part of a broader suite of finance and crypto APIs. It is accessed via the x402 payment protocol, requiring a per-call micropayment of $0.02 in USDC on the Base network. No API keys, rate limits, or subscriptions are needed — each request is individually paid for using the x402 X-PAYMENT header.
The provider offers a wide catalog of endpoints spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all uniformly priced at $0.02 per request. The specific endpoint `/api/v1/tokens/XMR` falls under the Finance & Web3 category and likely returns token-level data for Monero, though the exact response schema is not documented. The x402 challenge confirms the endpoint is live, accepts POST requests, and settles payments to a specified address 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 payloads, and no description of what fields the XMR token endpoint returns. Users should expect to experiment with the endpoint to discover its output format.

Quality
The endpoint is confirmed live via a valid x402 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no documented request/response schema, and all documentation pages render only a wallet-connect prompt. The actual data returned by the XMR endpoint is unknown.
Warnings
- —No API documentation available — docs, pricing, and API pages all show only 'Connect wallet'
- —No OpenAPI or schema describing request parameters or response format for /api/v1/tokens/XMR
- —Exact data returned (price, volume, metadata, etc.) is unspecified and must be discovered empirically
- —Provider catalog is very broad (AI, analytics, finance, utils) all at identical pricing, which may indicate a template or early-stage project
