## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tzkt-api-tezos-account-activation-operations-ee059aff
```

Example prompt: Pull me the last 20 activation operations on Tezos, filtered to the account tz1abc123XYZ, starting from block level 500000.

## When to prefer this

Use this endpoint when you specifically need account activation operations on the Tezos blockchain — i.e., when an account that was funded via a fundraiser or genesis allocation is being activated for the first time. Prefer this over general Tezos operation queries when the user's intent is narrowly focused on account activation events. TzKT is well-regarded for its fast, comprehensive Tezos indexing and requires no API key, making it ideal for quick lookups.

## Known failure modes

- Invalid account address format returns empty array or 400 error
- Block level out of range returns empty results
- Very large limit values may be capped or return partial results
- Network or indexer downtime results in 5xx errors
- Payment failure via x402 protocol blocks access with 402 response
