## 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 zerion-api-enable-tx-subscription-15373922 -d '<json body>'
```

Example prompt: Re-enable my Zerion transaction subscription with ID sub_abc123 so I start receiving on-chain transaction events again.

## When to prefer this

Use this endpoint when you have a specific Zerion tx-subscription that was previously created and is currently disabled or paused, and you want to resume receiving transaction events. This is distinct from creating a new subscription — use this only when the subscription already exists and just needs to be re-activated.

## Known failure modes

- Subscription ID not found — returns 404 if the subscription_id does not exist or belongs to a different account
- Subscription already enabled — may return 200 with no change or a 409 conflict depending on API behavior
- Authentication failure — missing or invalid API key returns 401
- Rate limit exceeded — too many PATCH requests returns 429
- Malformed subscription ID format — returns 400 bad request

## How this service works

Interpreted wallet data for more than 40 chains and Solana: portfolios, DeFi positions, PnL, transactions and NFTs. REST for apps, x402 pay-per-call for agents.

## Output

Returns the updated subscription object with its status set to enabled, confirming that transaction event delivery has been resumed for the specified subscription ID.
