Verification modes: If you provide context, Meerkat runs full grounded verification. Without context, only self-consistency checks run. For strongest results, always pass source data.
Pull the full verification record for compliance. Add ?include=session to get the complete correction chain, every attempt, every remediation, from first error to final resolution.

Domain-specific tolerance thresholds for numerical verification. Set domain in your verify request.
| Domain | Numerical tolerance | Example |
|---|---|---|
| healthcare | Zero tolerance on doses | Metoprolol 500mg vs 50mg = FLAG (critical) |
| financial | Zero tolerance on figures | Revenue $2.3M vs $23M = FLAG (critical) |
| legal | Strict on clause references | Section 4.2 vs 4.3 = FLAG (medium) |
| pharma | Zero tolerance on compounds | 10mg/mL vs 100mg/mL = FLAG (critical) |
| general | Standard thresholds | Default for all other content |
