LUNC liquidity data via x402 micropayment on Base for $0.02 per request
What it does
This endpoint at lowpaymentfee.com provides DeFi liquidity data for Terra Classic (LUNC) via the x402 payment protocol. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys or rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.
The provider, lowpaymentfee.com, hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities, all priced uniformly at $0.02 per request. This specific endpoint focuses on LUNC liquidity information, though the exact response schema is not documented. The site's docs, pricing, and API pages are gated behind a wallet-connect flow and contain no additional technical detail beyond the landing page.
Because no OpenAPI schema, request/response examples, or detailed documentation are available, the precise fields returned by this endpoint are unknown. Callers should expect a JSON response containing LUNC liquidity metrics, but the structure must be discovered empirically. The endpoint is confirmed live via a valid 402 challenge.

Quality
The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and the docs pages are empty wallet-connect gates. The specific data returned is entirely unknown, making this effectively a stub listing.
Warnings
- —No API documentation available — docs, pricing, and API pages all resolve to a wallet-connect prompt with no content
- —No request or response schema provided; callers must discover the response format empirically
- —The endpoint description is generic ('Premium API Access') and does not describe LUNC liquidity specifics
- —Provider hosts many endpoints with identical generic descriptions, raising questions about data quality and provenance
