Get the current price of LEO token via a pay-per-call x402 endpoint on Base.
What it does
This endpoint returns the current price of the LEO token (UNUS SED LEO) in JSON format. It is part of the lowpaymentfee.com platform, which offers a broad catalog of pay-per-request APIs spanning finance, crypto, AI, analytics, and utility services — all gated via the x402 payment protocol on the Base network.
The specific endpoint `/api/v1/tokens/LEO/price` costs $0.02 per request, paid in USDC on Base (contract 0x8335…2913). There are no API keys, no rate limits, and no subscriptions — each call is individually settled via an x402 payment header. The challenge specifies an "exact" scheme with a max amount of 20,000 base units of USDC (6 decimals), which equals $0.02 USD.
The platform advertises instant access and a simple pricing model across all its endpoints. Documentation pages exist at /docs, /api, /pricing, and /README but currently render only a "Connect wallet" prompt with no substantive technical documentation. As a result, the exact request body schema and response format for this token-price endpoint are not documented and must be inferred from the endpoint path and description.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing. However, there is no OpenAPI schema, no documented request/response format, and all documentation pages render only a wallet-connect prompt. The actual data returned is entirely inferred from the URL path.
Warnings
- —No API documentation available — /docs, /api, /pricing, and /README all render only a 'Connect wallet' prompt with no technical content.
- —Request body schema and response format are undocumented; example request/response cannot be provided.
- —The broader lowpaymentfee.com platform lists many endpoints but none have visible documentation, raising questions about maturity.
