How this service works
One id in, its official lifecycle state out - no need to know which line tracks it first. Covers 19 lifecycle lines (stablecoins, AI tools and datasets, neoclouds, DePIN, RWA, carbon projects, ESG funds, tariff measures and more): status band, birth/end dates, death type, lifespan, official source_ref. If two lines track the same id you get BOTH - nothing is picked for you. Unknown id -> 422 no_charge, not billed. Every record carries an offline-recomputable record_hash. $0.0050 per call.
Output
A JSON object containing one or more lifecycle records for the queried entity. Each record includes: status band (e.g. active, dead, deprecated), birth date, end date, death type, lifespan duration, official source reference (source_ref), and an offline-recomputable record_hash for integrity verification. If multiple industry lines track the same entity, all matching records are returned. Unknown entity IDs return a 422 no_charge error without billing.
Example use cases
Stablecoin collapse status check
“Can you look up the lifecycle record for terrausd-ust and tell me its current status, when it launched, when it ended, and how it died according to official sources?”
Neocloud operational status verification
“I need to know if CoreWeave is currently active or has it been wound down — pull its lifecycle state, lifespan, and any official source reference from the gauge lifecycle data.”
AI tool shutdown investigation
“Has Jasper AI been discontinued or is it still live? Get me the lifecycle status band, birth date, and death type if applicable — I want the official record, not just rumors.”
Technical details
Endpoint
GEThttps://api.truthbear.co/gauge/lifecycleWhen to prefer
Use this endpoint when you need the official, sourced lifecycle state of a specific named entity (stablecoin, AI tool, neocloud, DePIN project, carbon project, ESG fund, RWA, or tariff measure) and want a single authoritative lookup rather than time-series history or calibrated normalized signals. Prefer this over sibling endpoints like gauge/history-series (which gives full time-series exports) or gauge/calibrated (which adds normalized indices) when you simply need the current status band, dates, and death classification in one cheap call. The no_charge 422 for unknown IDs makes exploratory lookups safe and cost-free.
Side effects
- Unknown entity id returns HTTP 422 with a no_charge signal — the call is not billed
- Ambiguous entity tracked by multiple lines returns all matches unless narrowed with the optional industry parameter
- Stale or incomplete upstream source data may result in missing birth/end dates for some records
- If the entity id casing or slug does not match the catalog exactly, a 422 is returned
