No status page, SLA or changelog.\n\n## Before you call either\n\n### Apollo API + MCP\n\n1. Search people first at 0 credits, then enrich only the people you'll contact\n2. Branch on `error_details.code` and wait `retry_after_seconds` from the suggestions after a 429\n3. Limits are per team, so read the `x-minute-usage` and remaining headers before a bulk run\n4. Use a scoped key with only the endpoints the job needs. A master key reaches everything\n5. Get a person's approval before adding contacts to a sequence, since enrolment can start sending\n\n### Prospeo API + MCP\n\n1. Call `search_suggestions` before using location, technology or industry filters, or the search returns nothing\n2. Pass `person_id` values from search into `bulk_enrich_person`, 25 at a time\n3. Branch on the body `error_code`, not the HTTP status, which is 400 for most failures\n4. Set `enrich_mobile` only when needed. A mobile costs 10 credits against 1 for an email\n5. Use Enrich Person.
