How this service works
[SIGNAL+PROOF] Census record for one stablecoin (?symbol=): market cap, price, depeg state, lifecycle and time series, each with record_hash. Descriptive only, never a forecast or advice. No data -> 422 no_charge, not billed. $0.01 per call.
Output
A JSON object containing the stablecoin's market cap, price, depeg state, lifecycle status, and time series data points — each accompanied by a cryptographic record_hash for verification. Returns a 422 no_charge error (not billed) if no data is available for the requested symbol.
Example use cases
Depeg alert monitoring for USDT
“Check the TruthBear census record for Tether (USDT) and tell me whether it's currently in a depeg state and what its latest price is.”
DeFi risk dashboard stablecoin snapshot
“Fetch the full stablecoin census for DAI — I need the market cap, current price, depeg status, and lifecycle state for our DeFi risk dashboard.”
Auditable stablecoin data with proof hash
“Get me the verifiable census record for Frax (frax) from TruthBear, including the record hash, so I can confirm the data integrity in our compliance report.”
Technical details
Endpoint
GEThttps://api.truthbear.co/stable/coinWhen to prefer
Choose this endpoint when you need verifiable, hash-attested stablecoin data — especially price, market cap, depeg status, and lifecycle — for a single stablecoin by symbol. Ideal for compliance, auditing, or agent workflows requiring cryptographic proof of data integrity. Use /stable/preview first to discover available sample_ids. Prefer this over generic crypto price APIs when you need depeg state signals and record hashes rather than raw price feeds alone.
Side effects
- 422 no_charge: no data available for the requested stablecoin symbol — call is not billed
- Invalid or misspelled symbol returns no data
- Symbol not in TruthBear's covered stablecoin universe results in empty response
