How this service works
Keyless web search for AI agents, pay-per-call, no API key and no signup: natural-language query in, ranked organic results out (title, url, snippet) with source list. Neutral web access for research, RAG grounding and fact-check agents that cannot hold search API keys. $0.05 USDC x402 Base. Input: {"input": "your query"}. Ed25519-signed.
Output
A JSON object containing: a list of up to 20 search results (each with URL, title, and snippet), the result count, query echo, source label, and elapsed time in milliseconds. When extraction is enabled or auto-triggered, also includes answer_extract with the top URL's full cleaned markdown, character count, title, extractor method used, and estimated token count.
Example use cases
Real-time fact lookup for agent
“Search the web for the current Bitcoin price and return the top 5 results so I can see where the data is coming from.”
Research topic with source extraction
“Look up recent papers or articles about autonomous AI agent frameworks and fetch the full text of the best result as markdown — I want up to 8 links.”
Tech documentation retrieval
“Find the official documentation for the DuckDuckGo HTML search API and extract the full content of the top page so I can read the details.”

Endpoint
POSThttps://api.hergertsynthora.com/v1/websearch?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need both web search results and optional deep page extraction in a single paid call via x402 micropayment. Prefer it over generic search APIs when you want DuckDuckGo-backed results with clean markdown extraction of the top result, especially for agent workflows that need source text, not just snippets. Suitable for real-time research, fact-checking, and document retrieval tasks where freshness matters.
Side effects
- Query returns zero results if too niche or malformed
- Extraction fails if top URL blocks scraping or has no extractable content
- max_results out of range (must be 1–20) causes validation error
- Network timeout if upstream DuckDuckGo or target page is slow
- ok: false returned with error description for upstream failures
