## How to call it through Zero

```

Example prompt: Can you pull up the list of active API keys for my ZenSched organization so I can see which ones are currently in use?

## When to prefer this

Use this endpoint when you need to audit, verify, or enumerate the API keys associated with a ZenSched organization — particularly before key rotation, during security reviews, or to confirm provisioning. Prefer this over broader account exports when only credential inventory is needed.

## Known failure modes

- Payment failure: if the $0.01 USDC balance is insufficient, the call is rejected before returning data
- Organization not found: if no org is provisioned for the paying wallet, one is auto-created on first call
- No keys returned: if the organization has no active API keys
- Authentication error: if the request lacks valid payment credentials

## How this service works

ZenSched `api_key_list` — List active API keys (redacted prefixes only). Pay-per-call $0.01 USDC; the paying wallet owns the org (auto-provisioned on first call). Catalog: https://mcp.zensched.com/x402/tools

## Output

Returns a list of active API keys for the calling organization, with key values redacted to prefix-only for security. Includes enough identifying information to distinguish between multiple keys without exposing sensitive credentials.
