Search Delphi Markets

Search across all Delphi market clusters by keyword. Uses fuzzy multi-word matching where each word must appear somewhere in the title, but in any order.

For example, searching “british minister” will match titles like “Will the British Prime Minister resign?” even though the exact phrase does not appear.

What you get

• Delphi market clusters matching your keywords
• Each result includes the delphi_id, title, canonical exchange reference, cluster size, and last update time
• Each result also includes a markets array listing the individual exchange markets (exchange name, market_id, title) so you can navigate directly to each market’s detail endpoint
• Results ranked by cluster size (most cross-exchange coverage first)

Exchange market references

The markets array in each result contains entries like:

• { "exchange": "kalshi", "market_id": "AMAZONFTC-29DEC31", "title": "..." }
• { "exchange": "polymarket", "market_id": "0xabc...", "title": "..." }

Use these to construct detail endpoint URLs, e.g. /api/v1/klsi/AMAZONFTC-29DEC31/market
