How this service works
Pay-per-call Web3 agent services: wallet, token and agent security audits; token prices, depeg checks and portfolio valuation; cited fact-checking and source research.
Output
Returns an array of per-token checks each containing: whether the token is depegged (boolean), its current USD price, and deviation percentage from peg. Also includes an overall risk score (0-1), a confidence score, cited evidence claims with source URLs and content hashes for auditability, and the total cost of the call.
Example use cases
Pre-DeFi deposit stablecoin safety check
“Before I deposit into this yield farm, can you check if USDC (0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48) and USDT (0xdac17f958d2ee523a2206206994597c13d831ec7) are both holding their pegs within 1%?”
Portfolio depeg alert for stablecoin basket
“I'm holding USDC, DAI, and FRAX — their contract addresses are 0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48, 0x6b175474e89094c44da98b954eedeac495271d0f, and 0x853d955acef822db058eb8505911ed77f175b99e. Check all three for depeg using a 0.5% threshold and tell me if any are at risk.”
Emergency depeg detection during market stress
“Markets are crashing right now — can you immediately check if USDT at 0xdac17f958d2ee523a2206206994597c13d831ec7 has lost its dollar peg, and by how much? Use a 2% threshold.”
Technical details
Endpoint
POSThttps://crucible.unitynodes.com/finance/depegWhen to prefer
Use this endpoint when you specifically need to verify whether stablecoins are maintaining their USD peg, especially before DeFi operations, portfolio risk checks, or automated depeg alerts. It is distinct from general token price lookups because it provides deviation-from-peg logic, a boolean depegged flag, a risk score, and cited evidence — not just a raw price. Prefer this over raw oracle calls when you need auditable, sourced depeg determinations with confidence scoring.
Side effects
- Invalid or non-stablecoin contract address returns null price and deviation
- Network or oracle outage may return low confidence score
- Unsupported chain contract addresses may yield no pricing data
- Threshold value out of expected range (e.g. negative) may cause validation error
- Rate limiting or payment failure returns 402 Payment Required
