How this service works
Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.
Output
The raw upstream Tavily API response is passed through after payment verification — typically includes a list of search result objects with titles, URLs, and content snippets relevant to the query.
Example use cases
Real-time crypto market research
“Use Tavily to search for the latest Bitcoin price movements and any major news from the past 24 hours — I'm fine paying the per-query USDC fee.”
AI agent grounding with live web data
“My agent needs to answer a user question about current DeFi yields — can you run a Tavily web search for 'best DeFi yield opportunities 2025' and return the top results?”
Pay-as-you-go fact lookup for web3 app
“Look up the current Ethereum staking APR using Tavily search, billed through x402 micropayment so I don't need a monthly subscription.”
Technical details
Endpoint
POSThttps://quanta-roan.vercel.app/api/service/tavily?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need Tavily web search results without a recurring API subscription, want to pay per-query in USDC using the x402 protocol, or are building a web3/DeFi application that needs crypto-native payment for information retrieval. Prefer it over direct Tavily API access when you need micropayment billing and do not have or want to manage a Tavily API key directly.
Side effects
- Payment failure: insufficient USDC balance or x402 payment header missing/invalid returns 402 Payment Required
- Invalid path or query: malformed request body forwarded upstream returns an error from Tavily
- Tavily API key invalid or quota exceeded on the gateway side returns upstream 401 or 429
- Network timeout from upstream Tavily service results in a gateway error
- Malformed JSON body causes upstream to reject the forwarded request
