No status page covers it, quota numbers are only in the Cloud console, and searches need a warmup call first.\n\n**Microsoft Graph People and Contacts API.** Covers Outlook personal contacts with delta sync and a people API that ranks the people a user works with and supports fuzzy search, all under separate read and write permissions. Contact creates have no idempotency key, the status page needs JavaScript, and Microsoft has no current MCP server for contacts.\n\n## Before you call either\n\n### Google People API\n\n1. Send an empty searchContacts query first, wait a few seconds, then search\n2. Always pass personFields, such as names,emailAddresses,phoneNumbers, or the call fails\n3. Store nextSyncToken and do a full sync when you get EXPIRED_SYNC_TOKEN\n4. Send writes for one user one at a time and include the etag on updates\n5. Ask for contacts.readonly unless the task must create or change contacts\n\n### Microsoft Graph People and Contacts API\n\n1. Use /me/people?$search= for fuzzy lookups and /me/contacts for the saved address book, since they return different sets\n2. Keep the @odata.deltaLink from the contact delta function and call it on the next run\n3. Check for an existing contact with $filter on emailAddresses before creating one\n4. Honour Retry-After on 429 and keep to 4 parallel calls per mailbox\n5. Ask for Contacts.Read and People.Read unless the task must change contacts\n\n## Questions\n\n### Which is better for AI agents, Google People API or Microsoft Graph People and Contacts API?\n\nGoogle People API and Microsoft Graph People and Contacts API score within a point of each other on agent readiness, 65.2 (B) and 64.6 (B).
