# Resolve a pasted Polymarket/Kalshi/predict.fun market or event URL

`GET /search/resolve-url`

## Request

- Base URL: `https://data.kairos.trade`
- URL: `https://data.kairos.trade/search/resolve-url`
- Auth: API key in header `X-Client-Id` and API key in header `X-Api-Key` and API key in header `X-Api-Secret`

Parses `url` against known host patterns — polymarket.com `/event/<slug>/<market-slug>` (market) or `/event/<slug>` (event) or legacy `/market/<slug>`; kalshi.com ticker/event_id/market_id path segments; predict.fun equivalents. Unrecognized hosts or unmatched paths return an empty `/search/simple`-shaped body (200) so the frontend can fall back to a normal text search rather than erroring. On a match, resolves the market/event (for an event URL, every outcome market in that event) and returns the same `{results, groups?, singles?, meta}` shape as `/search/simple`, enriched with `correlations` only (ladder classification is skipped — a resolved URL is already a single market/event, not a broad set to collapse).

## Query parameters

- `url` string, required

## Response `200`

Resolved market/event in `/search/simple` shape, or an empty body if the URL wasn't recognized.

- SearchSimpleResponse: Shared envelope for /search/simple and /search/resolve-url. Both always include results/meta; groups/singles appear only when the underlying search was grouped (always true for /search/simple with group_results=true, and for /search/resolve-url on an event URL). classifiedGroups/absorbedMarketIds are only ever attached by /search/simple (group_results=true); /search/resolve-url never sets them. correlations is attached by both, best-effort, and absent if no counterpart markets were found.

## Other responses

- `401`: No valid credential presented — missing/invalid API-key headers, or an invalid/expired session token.
- `403`: Authenticated but not permitted. Three distinct causes: the session user is not invited (`Invite required`), the API key lacks the operation's scope, or API-key access to the requested venue is switched off (`API access is disabled for <provider>`). Admin and API-key callers bypass the invite check; session and admin callers bypass scope and venue checks.
- `422`: Request failed FastAPI parameter validation.
- `429`: Rate limit exceeded for this route's sliding window, keyed on the session `sub` when authenticated and on the trusted client IP otherwise. Honor `Retry-After`. A per-API-key data ceiling (set per credential) rejects with `{"detail": "API key data rate limit exceeded"}` instead of the `error` envelope below.
- `500`: URL resolution failed.
