Evidence Enrichment Gateway v1
Keep your database.
Patch what it is missing.
Send the facts already in your property record. CivicDataForge compares them with the official and permit evidence bound to the same paid workspace, then returns source-linked patches for what is missing, stale, conflicting or incorrectly zeroed.
Your IDs stay intact · normalized facts only · no provider credentials · request processed without persistence
Measure the value on your own records
One run produces the evidence and the scorecard.
The gateway also reports confirmed fields, null/empty recoveries, value conflicts and unresolved official fields. A false-positive rate is reported only when independent adjudicated labels are supplied to the benchmark harness.
The live path
From paid record to verifiable patch.
1. Bind
Create a paid property workspace for up to 25 records in one supported jurisdiction. The official evidence and its source clocks are fixed to that delivery.
2. Compare
Post your provider name, dataset, rights scope, exact property IDs, observation clocks and normalized facts. Credential material and unmatched IDs are rejected.
3. Verify
Receive non-persistent patches, benchmark counters and hash receipts. Production-signed batches can be checked through the verification endpoint.
Defensible by design
Your system remains the system of record.
- Identity first. A patch exists only when the supplied property ID belongs to the paid workspace.
- Presence is evidence. Absent, null, empty, zero and populated values remain separate states.
- Clocks stay separate. Customer observation time, source observation time and publisher update time do not collapse into one freshness badge.
- Rights travel with the result. The caller's authorization scope and each official source's controlling-use posture remain visible.
- Methods stay private. Customers receive results, schemas and verification receipts—not connector credentials or reconciliation implementation.
Available evaluation scope
Start where the official comparison is strongest.
Paid-workspace enrichment is available for Chicago/Cook County and Orlando/Orange County property facts, plus permit evidence included in the purchased workspace. It is not represented as nationwide MLS, title, appraisal, insurance or consumer-reporting coverage.
Bring one real export.
Use the self-service evaluation for up to 25 paid records. For a larger partner evaluation, send the target markets, field list, record count and acceptance metric. We will scope the comparison before asking you to replace any production process.
