Tools of ContactZapp
	Description		Read-only	Idempotent	Open world
`api_key_check`Returns the user the request acts for, the user's plan, the user's sign-in email and the scopes of the API key or connected app that made it. Any live key or access token can call it, so call it to test one.

`contact_change`Changes a contact, as editing it in ContactZapp does. Only the fields you send change. A field you leave out keeps its value. The change goes to every two-way account the contact is in, never to a read-only one. History records it as the user's change and names the API key or the connected app that made it. A contact waiting in Review duplicates cannot be changed until the review is decided: 409, `contact_pending_review`. Send an `Idempotency-Key` header to make a retry safe.

`contact_create`Adds a contact. If the user already has this person, the values may go to that contact instead: - If the user's Auto-Merge level covers the match, the values are added to the existing contact: 200, `merged`. - Otherwise a new contact is created: 201, `created`. If it may be a duplicate, it also waits in Review duplicates: 201, `needs_review`. ContactZapp saves the contact in one two-way account: the first one the user linked that keeps an address book and is not paused. The next sync copies it to the user's other two-way accounts, never to a read-only one. A create is never refused for the plan's contact limit. Over the limit, the contact is created frozen and `contact.frozen` is true. ContactZapp keeps a frozen contact but does not sync it until the user upgrades or frees a place.

`contact_find`Finds the user's contacts by email address, phone number or text. Give at most one of `email`, `phone` and `query`: - `email` finds the contacts with that address. Case does not matter. - `phone` finds the contacts with that number, however it is formatted. - `query` searches the way the Contacts screen's search does. - With none of them, every contact is listed, newest first. Deleted and merged contacts are never returned. For the next page, send the `nextCursor` you got as `cursor`, with the same filter. The last page has no `nextCursor`.

`contact_read`Returns one contact. `id` is the contact's `id` or its `publicId`, such as `CS-0042`. A deleted or merged contact is a 404, and so is another user's contact.

`event_list`Lists the events of one type, newest first. Zapier, Make and n8n poll this to start an automation. Each item's `id` never changes. Poll again and the items you already have come back with the same ids, with new ones on top. Skip the ids you have seen. - `contact.created`, `contact.updated`, `contacts.merged` and `account.needs_attention` come from History, and are kept as long as History keeps them. - `match.needs_review` lists each contact flagged as a possible duplicate and not yet merged. Its `id` changes when the flag is raised again. Each item carries what an automation needs, with no second call: - the contact's fields, or null once the contact is deleted or merged - for a merge, the ids of the contacts it absorbed - for an account, the account and why it needs attention	Lists the events of one type, newest first.

`sync_start`Starts a sync, the same as Sync now in ContactZapp. History shows it as a manual run. The answer is 202 with the sync's state, `queued` or `running`. If a sync is already going, you get that one back and no second one starts.	Starts a sync, the same as Sync now in ContactZapp. History shows it as a manual run.
