Hello Vercel team and community,

I'm researching Vercel's API capabilities for building a read-only deployment monitoring system. Before implementing anything or upgrading plans, I'd appreciate clarification on several questions.

1. Read-only API access

Does Vercel Hobby support an API token, OAuth integration, or other identity that can retrieve deployment and configuration metadata without permission to deploy applications, modify settings, or access environment-variable values?

If not, would Pro's Viewer role provide these capabilities, or is another plan or permission model required?

2. Deployment monitoring

Which APIs can provide information about:

Production and Preview deployment IDs and statuses

Queued, building, canceled, and failed deployments

Git integration and automatic deployment settings

Production-domain assignments and Deployment Protection settings

Can this information be retrieved through read-only permissions?

3. Deployment history completeness

Does Vercel maintain an authoritative history of all deployment activity, including short-lived or subsequently deleted deployments?

For example, if a deployment starts and finishes between two monitoring requests, is there an API, event log, or audit mechanism that would reliably capture it?

4. API freshness and privacy

Are there documented indexing delays, retention limitations, or completeness guarantees for deployment events?

Also, can API responses exclude sensitive information server-side, such as user email addresses or protection-bypass data, rather than simply filtering these fields after retrieval?

5. Rate limits and recommended approach

Would querying deployment and configuration metadata approximately once per minute be supported on Hobby, accounting for pagination and multiple API requests?

Would Vercel recommend API polling, webhooks, audit logs, or another provider-native monitoring mechanism?

I'm primarily interested in documented API capabilities and limitations. Links to official documentation would be greatly appreciated.

Thank you for your help!
