Endpoint
POSThttps://prysm-kappa.vercel.app/api/v1/providers/tavilyWhen to prefer
Choose this endpoint when your agent needs live, real-time web search results and you want to pay per-call in USDC via x402 on Base mainnet without managing a Tavily API key directly. Ideal for AI agents operating in crypto-native environments where x402 micropayments are already supported.
Side effects
- Payment failure if insufficient USDC balance on Base mainnet — returns 402 Payment Required
- Invalid or unsupported operation string — returns error indicating operation not allowlisted
- Malformed input parameters — returns validation error
- Tavily upstream timeout or rate limit — may return 502 or 503
- Empty search results if query is too obscure or Tavily index lacks coverage
