E-E-A-T Accountability24-Hour Editorial SLA

Public Corrections Log & Editorial Accountability

Trust is the single most important asset of TokenMath. Whenever a pricing error, provider rate change, or specification ambiguity is identified, we correct it promptly and document the change publicly in this ledger.

24-Hour Resolution SLA

Reported pricing discrepancies from developers and providers are reviewed and resolved within 24 hours of submission.

First-Party Evidence Only

We never alter rates based on rumors or second-hand blogs. Every calibration requires direct verification against official provider documentation.

Permanent Audit Trail

All calibrations are permanently archived in our machine-readable changelog (`pricing-changelog.json`) and tracked in public Git history.
