Built for reliable data extraction
The /v1/answers endpoint is designed for production use —
with built-in safeguards against hallucinations and missing data.
Custom JSON schema
Define exactly the shape of data you want back. The API maps every web-sourced fact into your schema automatically.
NOT_FOUND for uncertainty
When data can't be verified on the web, the field returns NOT_FOUND — never a hallucinated guess.
Sources included
Every answer comes with the URLs that were read to generate it. Full traceability, zero black-box outputs.
Real-time web data
Searches the live web on every call. No stale training data, no knowledge cutoff — always current.
Ask a question. Get structured JSON.
Pass a natural language question with an optional JSON schema and
get back a structured, sourced answer — grounded in live web data.
