- Payment of $0.001 USDC via x402 protocol not completed or rejected
- Invalid or malformed query parameter

- Empty string query returning undefined results

## How this service works

AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.

## Output

Returns a list of NFT collections matching the keyword query, likely including collection names, identifiers, and associated market metadata such as floor prices, volume, or other DeFi-relevant statistics.
