How this service works
Search Aggregator deep tier: Tavily+Exa+Firecrawl merged results with full page content and synthesized answer, fixed price $0.05 USDC. POST JSON body {query (required), max_results (optional 1-20, default 10)}. Mode is fixed by the path — no mode field needed, the quoted price is always the settled price.
Output
Returns a JSON object containing: a synthesized natural-language answer, an array of up to 20 search results each with URL, title, snippet, full page content, source provider (Tavily/Exa/Firecrawl), and published date; plus metadata including which providers were used, total latency in milliseconds, and any warnings encountered.
Example use cases
In-depth competitive research
“Do a deep search on 'best practices for B2B SaaS onboarding in 2024' and synthesize the top findings into a summary — pull full page content from up to 12 sources.”
Fact-checking a claim
“Search thoroughly for evidence on whether 'coffee consumption reduces risk of type 2 diabetes' — I want full article content and a synthesized answer from multiple sources, up to 10 results.”
Technical topic deep dive
“Look up everything you can find about 'WebAssembly component model specification' and give me full page content plus a merged answer across up to 20 results.”
Technical details
Endpoint
GEThttps://x402-production-d123.up.railway.app/search/deepWhen to prefer
Choose this endpoint when you need comprehensive, high-quality search results with full page content and a synthesized answer — not just titles and snippets. Ideal for deep research, fact-checking, or any task where surface-level snippets are insufficient and you need the actual article body. Prefer the fast tier ($0.01) if you only need titles/links/snippets. Use this deep tier when completeness and synthesis quality matter more than cost or speed.
Side effects
- Missing required 'query' parameter returns a 400-level error
- max_results outside 1-20 range may be clamped or rejected
- One or more upstream providers (Tavily, Exa, Firecrawl) may be unavailable, returning partial results with warnings
- Payment of $0.05 USDC not fulfilled via x402 protocol results in 402 Payment Required
- Some results may have null content if full page extraction fails
- High latency possible due to multi-provider aggregation
