Get the current price of MNT (Mantle) token via a pay-per-call x402 endpoint on Base.
What it does
This endpoint returns the current price of the MNT (Mantle Network) token. It is part of a broader suite of APIs hosted at lowpaymentfee.com, which offers data & analytics, AI/ML inference, finance/Web3, and infrastructure utility endpoints — all payable per request via the x402 protocol on the Base network using USDC.
The specific endpoint `/api/v1/tokens/MNT/price` accepts POST requests and returns JSON. Each call costs $0.02 in USDC (20,000 base units with 6 decimals) settled on-chain on Base. There are no API keys, no rate limits, and no subscription commitments — payment is handled entirely through the x402 payment header. The x402 challenge was confirmed live, returning a valid 402 response with payment parameters including the USDC contract address on Base (0x8335…2913) and a 300-second payment timeout.
Documentation beyond the landing page is sparse; the /docs, /pricing, /api, and /README pages all returned only a "Connect wallet" prompt with no additional technical detail. No OpenAPI schema, request/response examples, or detailed field descriptions were found. The endpoint appears to be part of a pattern where `/api/v1/tokens/{symbol}/price` returns token pricing data, but the exact response schema is not documented.

Quality
The x402 challenge is live and confirms pricing and payment details, but there is no OpenAPI schema, no documented request/response format, and all documentation pages beyond the landing page are empty stubs. The endpoint's actual behavior and response shape must be inferred.
Warnings
- —No OpenAPI or schema documentation available — response format is unknown
- —All doc/pricing/README pages return only a 'Connect wallet' prompt with no content
- —No example responses or field descriptions found for the token price endpoint
- —The broader site lists many endpoints but none have detailed documentation
