# Api Company Events Ma

`GET /api/company/events/ma`

## Request

- Base URL: `https://www.oxfordledge.com` (the document declares no server; this is the origin it was published from)
- URL: `https://www.oxfordledge.com/api/company/events/ma`
- Auth: none declared

Interpreted M&A events for a ticker.

SF-6 Option A Phase E1c (2026-05-08). Surfaces the
`corporate_events.ma_*` columns populated by
`services.event_interpreter.parse_ma_event` (Phase E1a) +
`tools/backfill_ma_interpretation.py` (Phase E1b).

Filters to event_type='acquisition_disposition' AND
ma_confidence_score >= min_confidence (default 0.4 — anything
below that is "we ran the extractor and it was unsure"; pass
`?min_confidence=0` to include zero-confidence rows for ops
debugging).

Returns empty list when:
  - PG is unavailable
  - ticker has no acquisition_disposition events
  - all rows are below the min_confidence threshold (rare; the
    backfill logs `extraction_rate >= 0.60` per plan §6 R1)

## Query parameters

- `ticker` string, nullable
- `limit` integer
- `min_confidence` number

## Response `200`
