How this service works
Cheap unified search across the ENTIRE change corpus (every feed at once): pass ?q=<keyword> and get matching changes ranked by significance, with a per-feed breakdown. Optional since / min_significance / limit / source. The one call to ask 'did anything change about X anywhere?' without knowing which feed to hit.
Output
A ranked list of matching changes from across all monitored feeds, with per-feed breakdowns indicating which feeds had hits, significance scores for each result, and metadata like source, timestamp, and summary text for each matching change.
Example use cases
Example prompt
“Search all the change feeds for anything related to 'fentanyl' — I want to see every recent update across drug recalls, federal rules, and any other feed, ranked by significance.”

Endpoint
GEThttps://oracles-production.up.railway.app/v1/searchWhen to prefer
Use this endpoint when you don't know which specific feed a change might appear in, or when you want to cast a wide net across all monitored domains (drug recalls, Federal Register rules, tariff changes, Maven updates, etc.) at once. It's the ideal 'catch-all' first query before drilling into a specific feed.

- No results found for obscure keyword returns empty findings array
- Payment not provided or insufficient results in 402 Payment Required
- Invalid 'since' date format returns 400 error
