How this service works
Google-quality web search for AI agents at $0.004 per search — the lowest x402 rate for full search results. Send a query, get back compact JSON built for LLM consumption: top organic results (position, title, url, snippet), the direct answer when one exists, a trimmed knowledge graph and related searches. Tune with num (1-10 results), country and language (2-letter codes). Zero results is a valid, honest answer. Pay per call in USDC, no account, no API key.
Output
A compact JSON object containing: an array of organic results (each with position, title, URL, and snippet), a direct answer string when one exists, a trimmed knowledge graph with key facts, and a list of related searches. Zero results is returned as an empty array rather than an error.
Example use cases
Real-time fact lookup for agent
“Search the web for 'current inflation rate United States 2025' and return the top 3 results plus any direct answer you find.”
Competitive research on a company
“Look up 'Anthropic Claude pricing plans' on the web and give me the top 5 organic results with snippets so I can compare what's out there.”
Localized search in foreign market
“Search the web for 'beste elektrische auto 2025' using country code NL and language nl, and return up to 8 results.”
Technical details
Endpoint
POSThttps://agentdata-api.sander-van-aard.workers.dev/web/searchWhen to prefer
Choose this endpoint when your agent needs live web search results without setting up an account or API key, and cost-per-call matters (at $0.008 USDC it is priced below typical x402 market rates). Ideal for agents that need compact, LLM-ready JSON rather than raw HTML, and for sporadic or low-volume lookups where a subscription model is wasteful. Prefer it over scraping solutions when you need structured snippets, direct answers, and knowledge graph data in one call.
Side effects
- Query string missing — returns 400 bad request
- Payment not sent or insufficient USDC — returns 402 payment required
- num parameter outside 1-10 range — may return error or default behavior
- Invalid country or language code — may return unexpected locale results
- Upstream search provider unavailable — returns 5xx error
- No results found for niche query — returns valid empty results array
