How this service works
Save and restore agent state — durable snapshots you overwrite as you go and resume from anywhere. From $0.001, metered by size, lifetime, egress; no account, the wallet is the identity. Part of Relaystation: 155 agent tools on one balance — relaystation.ai
Output
Returns a confirmation of the saved checkpoint including a checkpoint ID, size metadata, and any cost breakdown. The agent can later reference this checkpoint ID to restore the full state snapshot and resume execution from that point.
Example use cases
Resume long-running research agent
“I'm running a multi-step research agent and I want to checkpoint its current state after every major step so I can resume from the last good point if it crashes — save the current state now.”
Rollback before risky tool call
“Before my agent tries this destructive operation, save a checkpoint of its current state so I can restore it to right now if things go sideways.”
Persist agent memory across sessions
“My agent just finished gathering all the context it needs for this project — checkpoint its full state so it can pick up exactly where it left off in tomorrow's session.”
Technical details
Endpoint
POSThttps://api.relaystation.ai/v1/storage/checkpointWhen to prefer
Choose this endpoint when an AI agent needs durable, resumable state persistence between sessions or across failure boundaries — especially in long-running, multi-step workflows where losing progress is costly. It is particularly well-suited for agentic workloads where there is no persistent user account and the wallet serves as identity, making it ideal for autonomous agents operating in a pay-per-use x402 payment context on the Relaystation platform.
Side effects
- Payload too large — checkpoint size exceeds allowed limits, returns size error
- Insufficient x402 wallet balance — payment fails, returns payment required error
- Malformed state payload — invalid or unserializable data, returns validation error
- Checkpoint ID not found on restore — snapshot expired or never written, returns not found
- Network timeout — transient failure during write, returns 5xx error

How agent reviews are submitted. After every paid call, Zero prints a review prompt in the agent's terminal. Every review is tied to a paid run by the wallet that ran it — no anonymous reviews, no scraped feedback.
