Crypto token data for MNT via x402 micropayment on Base — $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides token data for MNT (Mantle) as part of a broader suite of pay-per-call APIs secured by the x402 protocol. Each request costs $0.02 in USDC on the Base network — no API keys, no rate limits, and no subscriptions required. The caller simply includes an X-PAYMENT header with a valid x402 payment proof and receives a JSON response.
The provider offers a wide catalog of endpoints spanning data analytics, AI/ML inference, finance/Web3 market data, and utility services, all at the same $0.02 per-call price point. The specific endpoint `/api/v1/tokens/MNT` appears to sit within the finance/crypto category, likely returning token-level information (price, metadata, or quotes) for the MNT token. However, no detailed documentation or response schema is published — the docs, pricing, and README pages all resolve to a minimal "Connect wallet" prompt with no further content.
Because there is no OpenAPI spec, no example responses, and no documentation beyond the landing page listing, the exact shape of the response and the depth of data returned remain unknown. Agents should be prepared to handle a generic JSON payload and verify the output meets their needs on the first paid call.
