What it does

This endpoint returns the current price of the CRV (Curve DAO) token. It is part of a broader suite of pay-per-request APIs hosted at lowpaymentfee.com, covering data analytics, AI/ML inference, finance/Web3 data, and utility services. The endpoint uses the x402 payment protocol, settling in USDC on the Base network at $0.02 per call. No API keys, rate limits, or subscriptions are required — each request is individually paid via an X-PAYMENT header.

The specific endpoint `/api/v1/tokens/CRV/price` sits within the Finance & Web3 category of the provider's API catalog. While the provider lists several token-related endpoints (e.g., `/api/v1/crypto/quotes`, `/api/v1/finance/prices`), this particular path targets CRV specifically. The x402 challenge confirms the endpoint is live, accepts POST requests, and returns application/json responses. The payment is settled to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on Base.

Documentation beyond the landing page is sparse — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. No OpenAPI schema, request/response examples, or detailed field descriptions are available from the crawl. The output schema in the x402 challenge only specifies that the input method is HTTP POST; no response body schema is provided.

Quality

0.40/ 1.00

The x402 challenge confirms the endpoint is live and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response format, and all documentation pages return only a wallet-connect prompt. The actual response structure must be inferred.

Warnings

  • —No response schema or example response available — actual JSON structure is unknown
  • —Documentation pages (/docs, /pricing, /api, /README) are all empty beyond a wallet-connect prompt
  • —No OpenAPI or machine-readable API specification found
  • —The specific /api/v1/tokens/CRV/price path is not listed on the landing page; it may be a dynamic route pattern like /api/v1/tokens/{symbol}/price
