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 JSON object with an 'ordered' boolean (true if delivered IDs match expected order), an array of 'mismatch_indices' indicating positions where IDs differ, an overall 'status' field ('pass' or 'fail'), and an 'evidence' object containing a SHA-256 hash of the input, confirmation that no data is retained, and the count of external calls made (always 0).
Example use cases
Pipeline handoff integrity check
“I just finished an agent pipeline step and got back these delivered IDs: ['task-A','task-B','task-C']. My expected order was ['task-A','task-B','task-C']. Can you verify the delivery order is correct and flag any mismatches?”
Multi-agent order fulfillment audit
“We processed a batch of orders and the fulfillment agent returned IDs ['item-9','item-7','item-8']. The expected delivery sequence was ['item-7','item-8','item-9']. Did the agent deliver them in the right order? Show me which positions are wrong if any.”
Agent result verification before payment release
“Before I release payment to the downstream agent, I need to confirm it delivered exactly these IDs in this order: expected ['doc-1','doc-2','doc-3'], delivered ['doc-1','doc-2','doc-3']. Can you run a delivery order check and tell me if it passes?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/agent-delivery-order-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a lightweight, cryptographically auditable check that a set of delivered item IDs matches an expected list in the correct sequence — especially in multi-agent pipelines where delivery integrity must be verified before proceeding. Ideal when you need a verifiable, privacy-preserving result (no data retention, SHA-256 evidence included) at near-zero cost ($0.001 USDC) without requiring prior signup.
Side effects
- Mismatched array lengths between expected_ids and delivered_ids may result in all indices beyond the shorter array being flagged as mismatches
- Exceeding 256 items in either array will trigger a validation error
- Individual IDs exceeding 8192 characters will be rejected
- Empty arrays may return a trivial pass result that doesn't reflect real delivery validation
- Payment failure via x402 will prevent the call from completing
