How this service works
Is this stablecoin's $1 peg a hard anchor or a soft peg: does its price historically return to $1 (a redemption/arbitrage anchor) or sit below it (the market pricing risk), and is it dislocated right now. Flags SOFT_PEG, BROKEN_HISTORY, DISLOCATION
Output
Returns a JSON object with an `ok` boolean, a `verdict` string classifying the peg as hard anchor or soft peg, an array of `flags` (each with a code like SOFT_PEG, BROKEN_HISTORY, or DISLOCATION and an explanatory message), and a `disclaimer`. Empty flags array means no issues detected.
Example use cases
Pre-investment stablecoin peg check
“I'm about to deposit into a DAI-USDC pool — can you verify that DAI has a real hard peg to $1 based on its historical price behavior, and let me know if it's currently off-peg?”
Algorithmic stablecoin risk assessment
“Is FRAX a hard-anchored stablecoin or does its price just sit near $1 without a true redemption mechanism? Check the last 90 days of price history and flag any dislocation.”
Collateral safety review for DeFi lending
“Before I use this stablecoin as collateral in a lending protocol, tell me whether its dollar peg has ever broken in recent history and if there are any SOFT_PEG or BROKEN_HISTORY flags I should worry about.”
Technical details
Endpoint
POSThttps://poolproof.ru/v1/stableWhen to prefer
Choose this endpoint when you need a structured, flag-based verdict on stablecoin peg quality backed by 90 days of historical price data — especially before depositing into yield pools, using a stablecoin as collateral, or assessing whether an algorithmic stablecoin is truly redeemable at $1. It is purpose-built for DeFi risk workflows and surfaces SOFT_PEG, BROKEN_HISTORY, and DISLOCATION signals that generic price feeds do not provide.
Side effects
- Unknown or unsupported stablecoin address returns error or empty result
- Insufficient price history (less than 90 days) triggers BROKEN_HISTORY flag
- Token address not recognized as a stablecoin returns invalid input error
- API payment failure due to missing or invalid x402 payment header
- Network or data provider outage may cause temporary unavailability
