x402-payable token data endpoint for COMP on Base, $0.02 per request via USDC.
What it does
This endpoint at lowpaymentfee.com provides token data for COMP (Compound) via an x402 payment-gated API. It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility endpoints, all priced at $0.02 per request and settled in USDC on the Base network.
The specific endpoint `/api/v1/tokens/COMP` returns JSON and is accessed via HTTP POST. Payment is handled through the x402 protocol: callers receive a 402 challenge containing payment details (pay-to address, asset, amount) and must include an `X-PAYMENT` header with a valid payment proof. The max amount required is 20,000 base units of USDC (6 decimals), which equals $0.02. No API keys, rate limits, or upfront commitments are required.
Documentation on the site is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint is confirmed live (returns a proper x402 challenge), but the exact shape of the response data for COMP token information is unknown and must be inferred from the endpoint path and the platform's "Finance & Web3" category description.

Quality
The endpoint is confirmed live with a valid x402 402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no examples, and all documentation pages are empty beyond a wallet-connect prompt. The actual data returned is entirely unknown.
