How this service works
The (most) everything API: 575+ pay-per-call endpoints for AI agents — ground-truth data, a full AI gateway, and agent infrastructure (storage, queues, watchers). USDC via x402, no signup, no API keys, and upto billing: pay actual usage, not the quote.
Output
Returns a synthesized natural language answer to the query along with supporting web results (up to the requested maximum), sourced from either general web pages or news outlets depending on the topic parameter.
Example use cases
Real-time news briefing for agent
“Search the news for 'Federal Reserve interest rate decision 2025' and give me a synthesized answer from up to 8 recent news results.”
Fact-checking a claim with live web
“Can you search the web for 'is ivermectin approved by the FDA for human use' and give me a ground-truth answer based on up to 5 general web sources?”
Current events research assistant
“Look up 'who won the 2025 UK general election' on the web — use general topic and pull up to 10 results so I get a thorough answer.”
Technical details
Endpoint
POSThttps://2s.io/api/ai/web-answerWhen to prefer
Choose this endpoint when an AI agent needs a web-grounded, synthesized answer to a natural language question without managing a search API key or scraping pipeline. It is especially useful for current events and news queries where real-time data is required. Prefer it over static knowledge bases when freshness matters, and over raw scraping when you want a synthesized answer rather than raw HTML.
Side effects
- Query too short (< 2 chars) or too long (> 400 chars) returns validation error
- No relevant web results found for obscure or very recent queries
- News topic filter may miss general-purpose answers if topic is set incorrectly
- Rate limiting or payment failure if USDC balance is insufficient
- Synthesized answer may be outdated if web index hasn't refreshed for very recent events
