## 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

```

Example prompt: Cancel my Vaultfire task escrow — my task ID is 0xabc123 — and trigger the USDC refund back to my wallet; I'm the original requester.

## When to prefer this

Use this endpoint when you need to cancel a specific Vaultfire protocol task escrow and reclaim the deposited USDC as the original requester. Prefer this over any generic contract-write endpoint when you specifically need the cancel-task flow with its refund logic enforced by Vaultfire contract rules.

## Known failure modes

- Caller is not the original task requester — only the requester can cancel (403 or contract revert)
- Task is already completed or in a non-cancellable state — contract revert
- Invalid or missing task ID — 400 bad request
- Insufficient USDC balance or payment header missing — payment failure
- Network or RPC error on-chain — 503 or timeout
- Task escrow already cancelled — idempotency conflict

## How this service works

Cancel a Vaultfire task escrow and trigger USDC refund per contract rules. Pay $0.15 USDC, sign in your wallet — only the task requester can cancel.

## Output

Returns confirmation that the task escrow cancellation has been submitted on-chain, along with a USDC refund trigger per the Vaultfire contract rules. May include an unsigned transaction for the caller to sign, or a signed receipt of the cancellation action.
