Retrieve IMX token data via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides token-level data for IMX (Immutable X) as part of a broader suite of finance, crypto, AI, and utility APIs. All endpoints on the platform are gated by the x402 payment protocol, settling in USDC on the Base network. The specific endpoint `/api/v1/tokens/IMX` sits within the Finance & Web3 category of the platform and likely returns token quote or metadata information for the IMX token.
The platform advertises a flat $0.02 per request across all its APIs, with no API keys, no rate limits, and no minimum commitments required. Payment is handled inline via the x402 protocol: callers attach a signed USDC payment in the `X-PAYMENT` header, and the endpoint processes the request upon verification. The x402 challenge confirms the endpoint is live, accepting payments to address `0x1A2B...85F3` in USDC (`0x8335...2913`) on Base mainnet, with a max amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals).
Documentation on the site is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no detailed description of what the `/api/v1/tokens/IMX` endpoint actually returns. The endpoint accepts POST requests based on the outputSchema in the x402 challenge. Without sample responses or schema definitions, the exact structure of the returned data is unknown.

Quality

Warnings
- —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content.
- —No OpenAPI or JSON schema describing request parameters or response format.
- —No example responses available; the exact data returned for /api/v1/tokens/IMX is unverified.
