How this service works
Web search that returns raw results plus an AI-synthesised, properly cited Markdown report. Pay per call in USDC over x402. No API key, no account.
Output
A JSON object containing: the AI model used, the original query, a cited Markdown answer string with inline reference numbers, an array of source URLs, a boolean 'grounded' flag, a detailed citations array (each with citation number, URL, quote, and title), and usage metadata (elapsed time in ms, input/output token counts, number of web searches performed).
Example use cases
Software version fact-check
“What is the latest stable release of Python right now? Search the web and give me a cited answer with links to official sources.”
Breaking news research brief
“Search the web for the latest developments on the EU AI Act and summarise what you find in a cited Markdown report.”
Competitive product comparison
“Search the web for a comparison of Mistral and GPT-4o pricing as of today, and give me a synthesised answer with numbered citations.”
Technical details
Endpoint
POSThttps://aisearch.x.c00l.site/answer?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a live, up-to-date answer grounded in current web content rather than a model's training data — especially for recent software versions, news, prices, or any time-sensitive fact. It is ideal for agentic workflows that must cite sources for trust and verifiability, and when you want to avoid managing API keys or subscriptions by paying per call in USDC via x402.
Side effects
- Payment not received or x402 handshake fails — request rejected before processing
- Query is too vague or ambiguous — AI may return a low-confidence or hedged answer
- Web search returns no relevant results — grounded flag may be false and answer quality degraded
- Rate limiting or upstream search quota exceeded — 429 or 503 response
- Claude model unavailability — 502 or 503 upstream error
