How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a deterministic hex key (SHA-256 derived) computed from the combination of item_id, version, and operation. Also returns the list of fields used, a confirmation that no data was retained, an input fingerprint (SHA-256 of inputs), the count of external calls made (zero), and a status of 'pass'. The result is verifiable and reproducible for the same inputs.
Example use cases
Prevent duplicate order shipment
“I need a dedupe key for item 'order-9921', version 'v1', operation 'ship' — I want to make sure we don't process the same shipment twice.”
Idempotent payment delivery tracking
“Can you compute a deduplication key for item 'payment-4410', version 'v2', and operation 'settle' so our agent doesn't double-charge on a retry?”
Verify unique agent task execution
“Generate a unique key for item 'task-0055', version 'v1', operation 'execute' — I need to confirm this agent task hasn't already run.”

Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/agent-delivery-dedupe-key?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-use, cryptographically verifiable deduplication key for agent delivery operations without any server-side data retention. It is ideal for AI agents that must ensure idempotency across retries or parallel executions and require an auditable, tamper-evident fingerprint. Prefer it over custom hashing logic when you need a standardized, verifiable schema (delx/util-agent-delivery-dedupe-key/v1) compatible with the Delx delivery contract ecosystem.
Side effects
- Missing required fields (item_id, version, or operation) may produce an incomplete or error response
- Inputs exceeding maxLength of 8192 characters may be rejected
- Payment failure via x402 (insufficient USDC balance or unsupported network) will block the request
- Service unavailability may return a non-200 HTTP status
