How this service works
[3-LEG] AI dependency chain, one dependency (?entity=openai-text-davinci-003): leading deprecation notices INCLUDING the sunset date the publisher itself scheduled -> current current availability -> realized lifecycle to deprecation, days alive (confirmation gate). A chain, not one reading: confidence = how many legs are lit, in order. Sources: vendor notices, source URL per record. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.25 per call.
Output
A 3-leg sequential chain response containing: (1) leading deprecation notices with the vendor-scheduled sunset date and source URL, (2) current availability status of the model, (3) realized lifecycle in days alive as a confirmation gate. Confidence score reflects how many of the three legs returned data. Returns 422 with no_charge if no data is available for the requested entity.
Example use cases
Check GPT-3.5 turbo deprecation timeline
“Look up the deprecation chain for openai-gpt-3.5-turbo-0301 — has OpenAI issued a sunset date yet, and is the model still available right now?”
Audit legacy Davinci model lifecycle
“Get me the full 3-leg lifecycle chain for openai-text-davinci-003 — I need the official deprecation notice, the sunset date, and how many days it was alive before going end-of-life.”
Monitor GPT-4 Vision preview status
“Check the AI dependency chain for openai-gpt-4-vision-preview — I want to know if there's a scheduled sunset date from OpenAI and what its current availability looks like.”

Endpoint
GEThttps://api.truthbear.co/gauge/dependency-regionWhen to prefer
Use this endpoint when you need authoritative, vendor-sourced deprecation lifecycle data for a specific AI model, including the exact sunset date the publisher scheduled. Prefer this over general web searches when you need structured, source-cited deprecation chain data with a confidence indicator, especially for dependency auditing or automated model-selection workflows. Best suited for individual model lookups; not a forecast or advisory service.
Side effects
- 422 no_charge: no data available for the specified entity ID — request is not billed
- Invalid or unrecognized entity ID not in the catalog — use GET /gauge/catalog?signal_id=<signal_id> to enumerate valid entities
- Partial confidence: only 1 or 2 legs return data, confidence score reflects the number of lit legs
- Network or upstream vendor notice source unavailable — partial chain returned
