x402-gated token data endpoint for ENJ on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides token data for ENJ (Enjin Coin) via the x402 payment protocol. It is part of a broader platform offering dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance/Web3 market data, and utility services — all gated behind x402 micropayments on the Base network.
The specific endpoint `/api/v1/tokens/ENJ` sits under the Finance & Web3 category of the platform. Based on the x402 challenge, each request costs a maximum of 20,000 base units of USDC (the asset at 0x8335…2913 on Base), which equals $0.02 USD (USDC uses 6 decimals). Payment is made via the "exact" scheme to the payTo address, with a 300-second timeout window. No API keys or rate limits are advertised; access is granted purely through the x402 payment header.
Documentation on the site is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no example request/response payloads, and no description of what fields the ENJ token endpoint actually returns. The endpoint is confirmed live (returns HTTP 402 with a valid x402 challenge), but without documentation it is unclear what data is included in a successful response (e.g., price, market cap, volume, metadata, etc.).

Quality
The endpoint is confirmed live with a valid x402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response format, and no examples. The docs pages are empty beyond a wallet-connect prompt, making it impossible to know what data the endpoint actually returns.
