Pay-per-call earnings data for CVX (Convex Finance) via x402 on Base network.
What it does
This endpoint provides earnings data for CVX (Convex Finance) through the lowpaymentfee.com finance API suite. It is part of a broader collection of Finance & Web3 endpoints offered by the provider, which also includes price feeds, exchange rates, token quotes, and gas estimates. The endpoint is accessed via HTTP POST and is gated by the x402 payment protocol, settling in USDC on the Base network.
Each request costs $0.02 (20,000 base units of USDC with 6 decimals). No API keys, rate limits, or upfront commitments are required — callers simply attach an x402 payment header to each request. The response is served as application/json.
Documentation beyond the landing page is extremely sparse. The /docs, /pricing, /api, and /README pages all returned only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what fields the earnings endpoint returns. The endpoint is confirmed live (returns a proper 402 challenge), but the lack of documentation means callers will need to experiment to discover the response shape.

Quality

- —No OpenAPI or JSON schema describing request parameters or response fields.
- —Response shape for CVX earnings data is unknown; callers must discover it experimentally.
