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.
Output
Returns a JSON object with coin_id, name, current observation data (state, peg deviation, death type, lifespan days depending on source), lifecycle info (peg/state/first_seen/last_seen/end_at), companion signal path for depeg/redemption pressure, source tier, capture date, data age in hours, and a record hash for integrity verification.
Example use cases
Stablecoin depeg early warning
“Check if TerraUSD (UST) is showing any depeg pressure or redemption stress — I need the current peg deviation and lifecycle state.”
Stablecoin due diligence for DeFi protocol
“I'm evaluating FRAX as collateral for a lending protocol — can you get me its current market cap, peg status, and how long it's been operating?”
Dead stablecoin post-mortem research
“I'm researching failed stablecoins — pull the lifecycle data for IRON stablecoin, including when it first launched, when it depegged, and its lifespan in days.”
Technical details
Endpoint
GEThttps://aeml-x402.zeabur.app/stable/coinWhen to prefer
Use this endpoint when you need a focused, single-coin deep-dive on a stablecoin's health, peg stability, lifecycle stage, and market metrics — especially when monitoring for depeg events or researching coin history. Prefer this over the full stablecoin triangle endpoint when you only need the census snapshot rather than the full depeg-pressure and redemption-flight triangle.
Side effects
- Unknown or unsupported symbol returns empty or error response
- Stale data if data_age_hours is high for illiquid or delisted coins
- Missing lifecycle fields for very new stablecoins with insufficient history
- Payment required (402) if USDC payment not provided
- Some fields may be null for coins with limited source coverage
