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
A JSON object confirming the operation outcome, including 'ok' boolean, the operation type performed, whether a conflict was detected, the decision made (e.g. 'reserved'), and a duplicate flag indicating whether this action was already seen.
Example use cases
Safe retry for paid API call
“I'm about to retry a paid webhook delivery for action_id 'webhook-send-449' — can you first check the idempotency status in namespace 'outbound-hooks' to make sure it wasn't already committed before I send again?”
Commit completed bounty claim
“My agent just finished and verified a GitHub bounty submission — commit the idempotency record for action_id 'bounty-claim-7723' with result_hash 'sha256-deadbeef' so it can't be double-submitted.”
Release a stale reservation
“The task for action_id 'data-extract-991' was cancelled — please release its idempotency reservation in namespace 'scrape-jobs' so another agent can safely pick it up.”
Technical details
Endpoint
POSThttps://bounty-engineer-x402-prod.onrender.com/v1/action-idempotency?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an autonomous agent needs exactly-once execution guarantees for critical or paid actions — especially when retries, network failures, or multi-agent coordination could cause duplicate side effects. It is specifically designed for agent commerce pipelines where double-execution means wasted spend or duplicate transactions. Prefer it over application-level deduplication when you need a shared, cross-process idempotency store with TTL-based expiry and commit/release lifecycle management.
Side effects
- Conflict detected if action_id is already reserved by another process (conflict: true)
- Duplicate detected if action was already committed (duplicate: true, decision may block re-execution)
- Invalid op enum value returns validation error
- TTL below 30 seconds rejected by schema minimum
- Missing action_id or namespace_key may cause server error or undefined behavior
- Payment failure (x402) if USDC balance insufficient for $0.002 call fee
