Cancel a job

try:
    await client.job(job_id).cancel()
except vorq.StateConflictError:
    print("too late: a provider has claimed the job, or it has already ended")

cancel() signs Cancel(jobId, issuedAt) with your wallet and posts it to the coordinator, which relays it to the chain. Things to know:

• Only unclaimed jobs can be cancelled. Once a provider has claimed a job, it ends by settlement, provider failure or reclaim after its SLA window, and the cancel is refused with StateConflictError.
• It needs the owning wallet. A client without a signer, such as one built with Client.from_session_token(token) alone, raises ValidationError before sending anything.
• Your clock matters. issued_at is stamped from your system clock and must be within ±600 seconds of the chain's block time.

After a successful cancel, the job's status is cancelled and handle.result() raises JobFailed with error_type="cancelled".

To cancel a whole batch, call await batch.cancel(); see Submit a batch. Through the OpenAI client, use client.responses.cancel(job_id).
