## 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 saylor-innovations-cardano-stake-account-lookup-c2066eb2
```

Example prompt: Can you check the Cardano stake account stake1uxyz... for me and tell me the total ADA balance, how much in rewards is available to withdraw, and which pool it's currently delegated to?

## When to prefer this

Use this endpoint when you need on-chain Cardano staking data for a specific stake address, including rewards, delegation, and vote delegation status. Prefer this over generic blockchain explorers when you need structured JSON output suitable for agent workflows, or when you want a simple $0.01 per-call cost without building your own Cardano node integration.

## Known failure modes

- Invalid or malformed stake address (not stake1... format) returns an error
- Unregistered stake address may return null for pool and reward fields
- Network timeout or upstream Cardano node unavailability
- Address with no delegation history returns null for delegated_pool

## How this service works

## Output

A JSON object containing the stake address, current registration status, delegated pool ID (or null), total ADA balance, UTxO ADA value, rewards earned, rewards available to withdraw, withdrawals total, reserves, treasury amounts, vote delegation details, and a note describing the data source and any caveats.
