## 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 vishwa-prediction-order-cancellation-c0208d20 -d '<json body>'
```

Example prompt: Cancel my pending buy order on prediction market MKTID-4892 for 10 contracts on the YES side — use my Solana wallet 7xKp...QmNr as the owner and payer pubkey.

## When to prefer this

Use this endpoint when an AI agent needs to cancel or revoke a previously placed prediction market order (buy or sell) before it executes, particularly when operating autonomously on Vishwa's agent-native banking infrastructure with pre-execution control over Solana-based capital flows.

## Known failure modes

- Order not found or already executed — returns success: false
- Missing required isBuy field — validation error
- Invalid or missing positionPubkey for sell order cancellation — error response
- Invalid Solana public key format — rejection
- Order already cancelled — idempotency conflict
- Insufficient authorization — owner pubkey mismatch

## How this service works

Vishwa is building agent-native banking infrastructure for autonomous capital, bringing pre-execution control to agent-driven payments and capital flows.

## Output

Returns a JSON object with a boolean 'success' field indicating whether the cancellation succeeded, and a 'data' object containing details of the cancelled order.
