How this service works
Save run state mid-task and resume after a crash.
Output
Returns a JSON object containing the created checkpoint resource (including a checkpoint ID and metadata about the saved state) along with a one-time management token used to retrieve or delete the checkpoint later.
Example use cases
Crash recovery for long-running pipelines
“I'm running a multi-hour data processing job and I want to save a checkpoint every 30 minutes so if the agent crashes I can pick up where I left off instead of starting over.”
Safe rollback before risky operations
“Before my agent attempts the bulk database migration step, save its current state as a checkpoint so I can restore to this point if something goes wrong.”
Multi-session agent task handoff
“My agent finished phase one of the report generation but I need to pause and continue tomorrow — save the current run state as a checkpoint so it can resume exactly where it stopped.”
Technical details
Endpoint
POSThttps://api.zenvault.eu/v1/checkpoints?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent runs long multi-step tasks that risk interruption, crash, or restart and you need reliable mid-task persistence. It is purpose-built for agent fault tolerance rather than general key-value storage, and pairs naturally with ZenVault's KV store and work queue. Prefer it over generic KV storage when you want a structured checkpoint primitive with a one-time management token for controlled access.
Side effects
- Payload too large — if the state blob exceeds size limits the API returns an error
- Invalid or malformed state data — missing required fields in the checkpoint body
- Payment failure — insufficient USDC balance or x402 payment header missing/invalid
- Rate limiting — too many checkpoint saves in a short window
- Expired management token — one-time token already consumed or checkpoint no longer exists
