Phone lookup, email enrichment, face search, KYC validation, and 20+ more endpoints. One API key. Clean JSON responses. Works in any stack.
IRBIS is a REST API that lets your application look up a phone number, email address, name, or face and get back a structured identity profile — linked accounts, location signals, fraud indicators, and more. You send a POST request, you get back JSON.
Everything your app needs to verify identities, enrich contact data, screen for fraud, and run compliance checks — all under one API key.
Register, grab your API key, and you're calling endpoints. Here's a real phone lookup request and what comes back.
# Step 1 — Submit the lookup curl -X POST \ https://irbis.espysys.com/api/developer/post \ -H "Authorization: Bearer YOUR_KEY" \ -H "Content-Type: application/json" \ -d '{ "searches": [{ "id": "phone", "term": "+14155552671" }] }' # Returns a lookupId immediately { "lookupId": "lk_8f3a91c2d4e5" } # Step 2 — Retrieve results curl \ https://irbis.espysys.com/api/developer/results/lk_8f3a91c2d4e5 \ -H "Authorization: Bearer YOUR_KEY"

Not a research tool — an API you plug into your product. Here's how different teams use it in production.
IRBIS searches across dozens of data sources at once. The async model means your app doesn't wait — it submits, stores the ID, and retrieves when ready.
/api/developer/credits endpoint to query your remaining credits programmatically — useful for usage dashboards or alerting when credits are low.Most identity APIs focus on one thing — email enrichment, or phone validation, or background checks. IRBIS covers all of them under one key.
