How this service works
What does the open web say about this query? Ranked title/url/snippet results for agents, served through an automatic multi-engine failover chain so a single call still answers when any one backend is blocked, rate-limited or timing out from a datacenter IP
Output
Returns a JSON object containing the total result count, the original query string, the search engine used (duckduckgo), and an array of result objects each with a URL, rank integer, page title, and a text snippet summarizing the page content.
Example use cases
Research DeFi protocol documentation
“Search the web for 'Uniswap v4 liquidity pool mechanics' and return the top 5 results so I can read up on how the new hook system works.”
Find ERC-20 token safety news
“Can you search for recent news about ERC-20 token rug pulls and scams in 2024 and show me the top 10 results with snippets?”
Locate Base network developer resources
“Search the web for 'Base network smart contract deployment guide' and give me the top 8 results so I can find the official docs.”
Technical details
Endpoint
POSThttps://eltociear-tokenguard.hf.space/web/search?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need quick web search results within a crypto/DeFi-focused agent context and want to pay per-call with x402 micropayments rather than managing a subscription API key. Prefer this over general search APIs when your agent is already integrated with the TokenGuard x402 payment flow on Base. Note that the underlying engine is DuckDuckGo, so expect privacy-respecting results without personalization.
Side effects
- Empty results if the query is too obscure or misspelled
- Payment failure (402) if USDC balance is insufficient for the $0.01 micropayment
- Rate limiting if too many requests are sent in quick succession
- DuckDuckGo backend timeout returning an empty results array
- Malformed query string causing a 400 bad request error
