What it does

This x402-enabled endpoint at `/api/v1/tokens/MKR` is part of the lowpaymentfee.com platform, which offers a collection of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities. Each call costs $0.02 in USDC on the Base network, settled via the x402 exact-payment scheme with no API keys, no rate limits, and no subscriptions required.

The specific `/api/v1/tokens/MKR` endpoint appears to return token-related data for MKR (Maker). Based on the site's broader Finance & Web3 category (which includes price feeds, exchange rates, token quotes, and gas estimates), this endpoint likely returns market or reference data for the MKR token. However, no detailed documentation, request/response schema, or example payloads are available from the crawled material — the docs, API, pricing, and README pages all resolve to a minimal "Connect wallet" stub.

Payment is made via the x402 protocol: callers attach an `X-PAYMENT` header with a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals) to the address `0x1A2B…85F3` on Base. The endpoint accepts POST requests and returns `application/json`. The payment timeout is 300 seconds.

The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no request/response schema, no examples, and the docs pages are empty stubs. The actual data returned by this endpoint is unknown beyond inference from the URL path and site categories.

Warnings

  • —No request or response schema provided; the exact data returned for MKR is unknown.
  • —The /api/v1/tokens/MKR path is not listed on the site's landing page among the advertised endpoints, so it may be undocumented or experimental.
