Get the current price of CFX token via a pay-per-call x402 endpoint on Base.
What it does
This endpoint returns the current price of the CFX (Conflux) token. It is part of a broader suite of APIs hosted at lowpaymentfee.com, which offers data & analytics, AI/ML inference, finance/Web3, and infrastructure utility endpoints — all payable per-request via the x402 protocol on the Base network using USDC.
The specific endpoint `/api/v1/tokens/CFX/price` accepts POST requests and returns JSON. Each call costs $0.02 in USDC (20,000 base units with 6 decimals) settled on Base to the provider's wallet. No API keys, rate limits, or subscriptions are required — payment is handled inline via the x402 `X-PAYMENT` header. The x402 challenge was confirmed live, returning a proper 402 response with version 1 of the protocol.
Documentation beyond the landing page is extremely sparse — the /docs, /pricing, /api, and /README pages all returned only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the response schema. The endpoint appears functional based on the 402 challenge, but the lack of documentation makes it difficult to confirm the exact response format or any query parameters.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no documented request/response schema, no example payloads, and all documentation pages returned only 'Connect wallet' with no content. The listing is effectively a stub with only the x402 challenge and landing page to work from.
Warnings
- —No OpenAPI or schema documentation available — response format is unknown
- —All doc/pricing/API pages return only 'Connect wallet' with no technical content
- —No example request or response payloads could be found
- —The broader lowpaymentfee.com site lists many endpoints but none have detailed docs; quality of data returned is unverifiable
