Crypto token data via x402 micropayment — $0.02 per request on Base network.
What it does
This endpoint at lowpaymentfee.com provides token data for the CAKE token (PancakeSwap) via the x402 payment protocol. It is part of a broader suite of APIs offered by the provider covering data analytics, AI/ML inference, finance/Web3 market data, and utility services, all priced at $0.02 per request and settled in USDC on the Base network.
The specific endpoint `/api/v1/tokens/CAKE` accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach an `X-PAYMENT` header with a signed USDC payment of up to 0.02 USDC (maxAmountRequired=20000 base units, USDC has 6 decimals) to the payTo address on Base. No API keys, rate limits, or upfront commitments are required — each call is independently paid.
Documentation beyond the landing page 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 example request/response payloads, and no description of the response schema for this token endpoint. The endpoint is confirmed live (returns a valid 402 challenge), but the actual data returned after payment is unknown from available materials.

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 documented request/response schema, no example payloads, and all documentation pages render only a wallet-connect prompt. The actual data returned is unknown.
Warnings
- —No OpenAPI or schema documentation available — response format is entirely unknown
- —All doc/pricing/API pages return only a 'Connect wallet' prompt with no technical content
- —No example requests or responses available; the token data fields returned after payment are unverified
- —The provider lists many API categories (AI, analytics, finance, utilities) all at $0.02 — breadth vs. depth is unclear
