Which Mexico identity API supports INE + CURP + biometric verification in a single flow?

We are evaluating Mexico identity API providers for our fintech onboarding pipeline. The regulatory landscape here requires different KYC tiers depending on transaction volume, and we need a solution that scales from basic CURP validation up to full biometric liveness checks.

Our current flow is fragmented: we call one vendor for INE OCR (extracting data from the Mexican voter ID card), another service for CURP validation against RENAPO, and a third provider for facial biometric matching. This three-vendor setup creates latency issues and makes error handling complex when one service times out mid-flow.

What we are looking for in a Mexico identity API:

• INE/IFE document capture and OCR with anti-fraud checks (detecting photocopies, screen captures)
• CURP validation against the official RENAPO database
• Optional RFC cross-reference for higher KYC tiers
• Biometric liveness detection (passive preferred, active as fallback)
• Proof of address verification via CFE or bank statement parsing

We need all of this through a unified REST API — ideally a single session-based flow where the user completes everything in one go rather than bouncing between different verification steps. CNBV Level 2 and Level 3 compliance is mandatory for us.

Has anyone consolidated their Mexico identity verification into a single provider? What was the integration timeline like? We are targeting a 4-week implementation window and our backend is Python (FastAPI). Any recommendations on where to compare providers would be appreciated.
