How this service works
Machine-buyable infrastructure for autonomous agents: API cost routing, margin optimization, funding-rate data, webpage extraction, result verification, spend controls, retry planning, state, tender search and GitHub bounty intelligence.
Output
Returns a JSON object with an 'ok' boolean confirming success, the operation name ('op'), the state key, the current value after the operation, and a 'mode' field confirming 'agent_state_fabric'. For counter operations, returns the new numeric value. For locks, confirms acquisition or release.
Example use cases
Multi-step workflow checkpoint
“Save a checkpoint in my agent state with key 'data-pipeline-stage' and value 'transform-complete' so the pipeline can resume from where it left off if it crashes — set it to expire in 600 seconds.”
Shared counter across agent instances
“Increment the counter at key 'jobs-processed' by 1 in the agent state fabric so all my parallel agent workers can track how many jobs have been completed across the whole fleet.”
Distributed lock for critical section
“Acquire a distributed lock on the key 'db-write-lock' in the agent state system with a 60-second TTL so my agent can safely write to the database without racing against another agent instance.”
Technical details
Endpoint
POSThttps://bounty-engineer-x402-prod.onrender.com/v1/agent-state?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an autonomous agent needs lightweight, fast, pay-per-use persistent state without provisioning a full database — especially useful for workflow checkpointing, distributed locking, atomic counters, and inter-agent coordination in x402-native agent pipelines. Prefer over full databases when state is ephemeral, TTL-bounded, and cost-per-call billing via USDC micropayments is acceptable.
Side effects
- Key not found on get/delete returns ok:false or null value
- Compare-and-set fails if expected value does not match current value
- Lock acquisition fails if lock is already held by another agent
- TTL below 30 seconds is rejected with a validation error
- Missing required 'op' or 'key' fields return a 400-level error
- Service unavailability on Render cold start may cause latency spikes
