How this service works
Quick web answer with citations (Exa upstream): ask one factual or current question and get a concise synthesized answer plus source URLs and publication dates. Optimized for fast lookups and agent loops; use /llm-research for a deeper multi-section research report, reasoning, image analysis, or webpage summarization. Keyless, pay-per-call, cached by query.
Output
A JSON object containing a synthesized answer string, the original query, the AI/search provider used (e.g. Exa), an array of citations with URLs and titles, a generatedAt timestamp, and metadata including a validUntil freshness window and staleness indicator.
Example use cases
Real-time DeFi protocol risk assessment
“I need to know what happened with Aave's governance last week. Has there been any major security update or proposal I should be aware of? Give me the latest details with sources.”
Current crypto regulation compliance check
“What's the most recent guidance from the SEC on staking rewards? I need to understand the current regulatory stance for our DeFi product.”
Emerging blockchain standard impact analysis
“Can you explain what ERC-6909 is and why it matters for token standards? I want a concise overview with reliable sources so I can brief my team.”
Technical details
Endpoint
GEThttps://x402.ottoai.services/web-answerWhen to prefer
Use this endpoint when you need a quick, cited factual or current-events answer to a single question in natural language, especially for crypto, DeFi, or blockchain topics. Prefer it over a raw web scraper when you want an AI-synthesized answer with source citations rather than raw HTML. Ideal for questions up to 96 characters that need a grounded, up-to-date response with provenance.
Side effects
- Query exceeds 96-character limit — request rejected or truncated
- Question is too vague or ambiguous — answer may be low quality or off-topic
- No web sources found for the query — empty or degraded response with meta.degraded=true
- Payment not received or USDC balance insufficient — 402 response blocking the call
- Rate limiting if too many calls in quick succession
- Answer may be stale if validUntil has passed — check meta.stalenessSec
