How this service works
Explore 330 pay-per-call x402 API services and 27 agent-native digital products, with Base USDC pricing, secure Polar checkout, and free discovery.
Output
Returns a JSON object containing an 'address_set_comparison' field with the structured comparison result, a 'warnings' array for any issues detected, an 'evidence_scope' field indicating the data source (e.g. caller_supplied_data), and a full receipt with payment, execution, and latency metadata plus a result SHA-256 hash for integrity verification.
Example use cases
Reconcile shipping vs billing address lists
“I have two address lists — one is our shipping addresses and the other is billing addresses for the same customers. Can you compare them and flag any mismatches or inconsistencies?”
Detect duplicate addresses across datasets
“We merged two customer databases and I need to know if there are overlapping or duplicate addresses between the two sets. Here are the two address lists: [Set 1] and [Set 2] — what do they share and what's unique to each?”
Verify address set equivalence for compliance
“Before we finalize this vendor contract, I need to confirm that the delivery locations they listed match exactly with the locations in our approved facility register. Can you compare these two address sets and tell me if they're equivalent?”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/address_set_compare/invokeWhen to prefer
Choose this endpoint when you need a fast, auditable, per-call comparison of two or more address sets with cryptographic receipt and evidence scope metadata. It is ideal for compliance, logistics reconciliation, or identity deduplication workflows where you need a structured diff of address collections rather than geocoding, validation of individual addresses, or full postal standardization.
Side effects
- Input string too short (below minLength of 2) returns a validation error
- Input exceeds maxLength of 65536 characters causing rejection
- Malformed or unparseable address set string may yield incomplete comparison or warnings
- Payment failure via x402 protocol results in no execution and an error status
- Network or service errors may return a non-'succeeded' status in the receipt
