How this service works
[BATCH+PROOF] Full stablecoin census, latest day, ranked by market cap; lifecycle flags terminated and depegged. Add ?verifiable=1 and every row carries _hash_core so you can recompute the hash offline without trusting us. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.09 per call.
Output
A JSON array of all tracked stablecoins ranked by market cap as of the latest available day. Each row includes the stablecoin name, market cap, rank, and lifecycle flags for 'terminated' and 'depegged' status. When ?verifiable=1 is passed, each row also includes a _hash_core field — the canonical pre-image string you can hash offline to verify the record_hash without trusting the API. Returns a 422 with no charge if no data is available.
Example use cases
Daily stablecoin health monitoring
“Give me today's full stablecoin census ranked by market cap and flag any that are depegged or terminated — I want to know the current state of the market.”
Offline-verifiable compliance audit
“Fetch the complete stablecoin census with the cryptographic hash included on every row so my compliance team can recompute and verify each record offline without trusting the source.”
Depegged stablecoin risk check
“Which stablecoins in today's census are flagged as depegged or terminated? I need to make sure my portfolio doesn't have exposure to any of them.”
Technical details
Endpoint
GEThttps://api.truthbear.co/stable/censusWhen to prefer
Choose this endpoint when you need a comprehensive, ranked snapshot of the entire stablecoin market for the current day, especially when lifecycle status (terminated, depegged) matters or when cryptographic auditability is required. It is a batch overview endpoint — prefer it over per-coin lookups when you need the full universe. It is descriptive only and should not be used for forecasting or investment advice.
Side effects
- 422 no_charge: no stablecoin data available for the latest day — not billed
- Missing or malformed query parameters may produce unexpected behavior
- Stale data if the latest day's data has not yet been ingested
