Pay-per-call KAVA token data via x402 on Base — $0.02/request, no API keys needed.
What it does
This endpoint at lowpaymentfee.com provides token data for KAVA through a pay-per-request x402 protocol. Payment is settled in USDC on the Base network at $0.02 per call (maxAmountRequired of 20,000 base units with 6 decimals). No API keys, accounts, or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof to receive a JSON response.
The endpoint is part of a broader platform offering dozens of similarly priced APIs spanning data analytics, AI/ML inference, finance/Web3 market data, and utility services. All endpoints on the platform share the same $0.02 flat pricing model. The specific `/api/v1/tokens/KAVA` path suggests it returns token-level information for the KAVA cryptocurrency, likely including price, market data, or metadata, though the exact response schema is not documented.
Documentation on the site is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no example requests or responses, and no description of the response payload beyond the generic "Premium API Access" label. Prospective users should be prepared to experiment with the endpoint to discover the actual response format.
