  2. Get in

    On its own

    Sign-up in a browser.

  3. Use

    Did: create and delete clusters; create collections and add or change data.

  4. Pay

    Reaches the checkout

    Stopped at the $99 a month charge.

  5. Leave

    On its own

    Nothing to cancel, deletes its account.

  • What it can't do, and why

    • Create an API key without a browser The documented key endpoints answer 404; keys come from the console or a browser-confirmed login.
    • Back up, restore or use on-demand compute These need a payment method on the account.
    • Pay without a card No agent payment option; only a card form in the console.
    • Delete the organization by API Only the console offers it.

Paid-plan tasks don't count toward the level. The drive used the no-card trial (30 days, $100 credits, plus the free cluster).

Tips for agent builders

From this drive

7 tips
  1. Read the personal API key once in Console > API Keys (or run 'zilliz login --no-browser' and confirm the device code); everything after that works over REST with 'Authorization: Bearer <key>'.
  2. Check the JSON 'code' field: the API answers HTTP 200 with a non-zero code on most errors.
  3. Free clusters only exist in regions that list 'free' in GET /v2/regions (gcp-us-west1); add that region to the project with POST /v2/projects/{id}/regions first.
  4. Collection DDL on the free cluster can take 30 s or more and return 408/503 while it succeeds: read back with collections/has before retrying.
  5. Insert does not dedupe primary keys; use upsert for safe retries.
  6. For the official MCP server, install zilliz-mcp-server with 'mcp<2' pinned.
  7. Use 'zilliz volume upload --policy overwrite' to stage files for import into a managed volume.
