source: Searched the ION Analytics Data Portal documentation for the Dealogic surfaces and read every
  parameter description in the eight OpenAPI documents in openapi/; probed the API hosts unauthenticated
  on 2026-09-05.
limit_count: 0
detail: No rate limit is published anywhere - not a requests-per-second figure, not a daily quota, not
  a burst allowance. No harvested operation declares a 429 response, and no RateLimit-*, X-RateLimit-*
  or Retry-After header appears in any spec or in any observed response. Unauthenticated probes return
  401 with a zero-byte body and no rate-limit headers, so nothing can be read off the wire either.

  note: 'Probed GET https://spac.analytics.dealogic.com/odata/SpacEntry and GET https://bank.analytics.dealogic.com/
    on 2026-09-05: neither returns any rate-limit header.'
status_on_exhaustion: null
query_complexity_limits:
  note: What Dealogic DOES publish is per-request query complexity caps on the OData SPAC surface. These
    bound the cost of a single call, not the rate of calls, so they are recorded here separately rather
    than as rate limits.
