Get the current price of RUNE token via a pay-per-call x402 endpoint on Base.
What it does
This endpoint returns the current price of the RUNE token (THORChain) in JSON format. It is part of the lowpaymentfee.com platform, which offers a collection of x402-protocol pay-per-request APIs spanning data analytics, AI/ML, finance, crypto, and utility services. All endpoints on the platform use the x402 payment protocol, settling in USDC on the Base network.
The specific endpoint at `/api/v1/tokens/RUNE/price` accepts POST requests and charges $0.02 per call (20,000 base units of USDC, which has 6 decimals). Payment is handled via the x402 `X-PAYMENT` header — no API keys, accounts, or rate limits are required. The endpoint was confirmed live, returning a proper 402 challenge with x402 version 1.
The platform advertises a broad set of similarly priced endpoints ($0.02 each) covering token quotes, exchange rates, gas estimates, sentiment analysis, text summarization, embeddings, geocoding, and more. Documentation pages exist but appear to require a wallet connection and contain no additional technical detail beyond what the landing page and 402 challenge provide. No OpenAPI schema or detailed response format documentation was found.

Quality
The endpoint is confirmed live via a valid 402 challenge, and pricing is clear ($0.02/request in USDC on Base). However, there is no OpenAPI schema, no documented response format, no example responses, and the docs/pricing/README pages all resolve to a bare 'Connect wallet' stub with no useful content.
Warnings
- —No response schema or example response documented — output format is unknown
- —Documentation pages (/docs, /pricing, /api, /README) contain no useful content beyond 'Connect wallet'
- —No OpenAPI or machine-readable schema available
- —The specific endpoint path /api/v1/tokens/RUNE/price is not listed on the landing page; it was only discovered via the probe URL itself
