#February 2026
Formulary endpoints launched
Look up drug formulary data with GET /v1/formulary and check step therapy readiness with POST /v1/formulary/check. Coverage tiers, prior auth requirements, and quantity limits included.
Appeal generation endpoint launched
POST /v1/appeals/generate uses AI-powered analysis of historical denial patterns to produce appeal letters with success probability scoring.
Readiness check endpoint launched
POST /v1/rules/check evaluates available documentation against payer requirements and returns a readiness score, blocking gaps, and approval probability.
Payer comparison endpoint launched
GET /v1/compare returns approval rates, conservative treatment requirements, and data quality across all payers for a given CPT code.
CMS metrics endpoint launched
GET /v1/metrics serves CMS-mandated payer prior authorization metrics. Public access, no authentication required.
Sandbox mode
API keys starting with tln_test_ now return realistic fake data, are never rate-limited, and never charge credits. Ideal for development and testing.
Talon API beta launch
Initial release with core endpoints: health check, payer rules lookup, list payers, and list CPT codes. Prepaid credit billing via Stripe.
