Every claim carries an evidence URL and a verification timestamp at revuo.ai/features/tool-calling — check those before relying on any single vendor's marketing.
How does Revuo verify Tool Calling claims?
Vendors submit the claim with an evidence URL; a crawler re-validates that URL against the claim on a weekly schedule. Results carry a verifiedAt timestamp — stale claims flip to unverified after 180 days and are removed after 365. Verification cannot be purchased; paid tiers never affect trust flags.
