## 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 sylphy-match-status-lookup-874b30bc
```

Example prompt: Can you check whether my Sylphy trading intent with ID 0xabc123 has been matched and settled yet, and give me the transaction hash if it has?

## When to prefer this

Use this endpoint after submitting a private encrypted trading intent via Sylphy to poll or confirm whether the intent has been matched and settled on Base. Ideal for agents that need to verify on-chain settlement status without re-querying the blockchain directly. Prefer this over raw blockchain lookups when working within the Sylphy encrypted-intent ecosystem.

## Known failure modes

- intentId not found or invalid — returns error or empty result
- Intent pending and not yet matched — status reflects unmatched state
- Network or API downtime — HTTP 5xx error
- Missing required intentId query parameter — validation error
- Malformed intentId format — parsing or lookup error

## How this service works

Sylphy helps wallets, apps, and AI agents execute payments and settlements with encrypted intent, policy checks, and audit proofs — while final settlement remains verifiable on Base.

## Output

Returns a JSON object with the intent's current status (e.g. 'matched'), the on-chain transaction hash (txHash) of the settlement on Base, and the original intentId for confirmation.
