Trust the evidence, not a status badge.

Production source checks run every 10 minutes, with a separate daily operational report at 08:00 UTC. Each vendor row below shows its actual latest attempt and successful verification time, so coverage awaiting refresh—or needing attention—remains visible.

VendorSpies fetches each configured public source, hashes the fetched HTML, extracts configured price or rate-limit fragments, and compares structured values with the verified baseline. Model-catalog deltas must repeat across two consecutive successful runs before an existing model's canonical values are updated. New-model launch events also require a second observation. Public model events then have a six-hour stability hold after confirmation. Rapid reversals remain available for operator investigation but are withheld from public feeds, change reports, and public change counts.

Failed extraction creates a snapshot with a parser error instead of silently reporting success. The prior verified baseline remains intact while the affected vendor is marked for attention.
