Real-time XMR (Monero) price data via x402 micropayment on Base network, $0.02 per request.
What it does
This endpoint returns the current price of XMR (Monero) through a pay-per-call x402 protocol. It is part of a broader suite of APIs hosted at lowpaymentfee.com that cover data analytics, AI/ML inference, finance, crypto, and utility services. Each call costs $0.02 in USDC on the Base network, with no API keys, rate limits, or subscriptions required.
The endpoint accepts POST requests and returns JSON. Payment is handled via the x402 protocol: callers include an X-PAYMENT header with a signed payment of up to 20,000 base units of USDC (i.e., $0.02) on Base. The payment is sent to the provider's address (0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3) and the response is delivered immediately. The x402 challenge was confirmed live, returning a proper 402 with version 1 challenge metadata.
Documentation beyond the landing page is sparse — the /docs, /pricing, /api, and /README pages all returned only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The endpoint is clearly live and priced, but the exact shape of the returned price data must be inferred from the endpoint path and the site's general "Finance & Web3" category description.

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, no example payloads, and all documentation pages return only a wallet-connect prompt. The listing is functional but severely under-documented.
Warnings
- —No OpenAPI or schema documentation available — response format is unknown
- —All doc/pricing/README pages return only 'Connect wallet' with no content
- —No example responses or field descriptions for the price data returned
- —No SLA, uptime, or rate-limit guarantees documented
