How this service works
RFS Stablecoin Yield Risk Index (SYRI): a 0–100 risk score and band (Conservative / Moderate / Speculative) for a stablecoin yield venue. Call BEFORE parking or routing stablecoins into a lending pool, RWA, or yield product to check its risk. Covers Aave, Morpho, Ondo, Ethena, Sky, Reserve, and more. By RFS Consulting
Output
Returns a JSON object containing: the entity slug, a composite_score (0–100 where higher = lower risk), a tier enum ('Conservative', 'Moderate', or 'Speculative'), a tier_label, an as_of timestamp, methodology_version, and optional disclaimer and license fields.
Example use cases
Pre-deposit DeFi yield check
“I'm about to deposit stablecoins into Morpho — can you check the SYRI risk score for usdc-morpho and tell me what tier it falls into before I commit?”
Comparing RWA stablecoin risk
“I'm deciding between Ondo OUSG and Ethena USDe for a conservative yield allocation — can you pull the SYRI scores for ousg and usde so I can compare which one is lower risk?”
Automated routing safety gate
“Before my yield-routing bot sends any funds to a new stablecoin venue, check the SYRI score for sdai and block the transfer if it comes back as Speculative.”
Technical details
Endpoint
GEThttps://syri.rfsrisk.ai/api/scoreWhen to prefer
Use this endpoint when an AI agent or automated system needs a quick, structured risk signal before routing or parking stablecoins into a yield venue. It is the right choice when you need a pre-built, regularly updated index score rather than running your own on-chain analysis. Particularly valuable for Aave, Morpho, Ondo, Ethena, Sky, and Reserve protocols. Prefer this over generic DeFi data APIs when you need a single normalized risk number and tier rather than raw TVL or APY data.
Side effects
- Unknown or misspelled entity slug returns an error or empty result
- Stale data if the venue has not been recently re-scored (check as_of timestamp)
- Payment failure (x402) if USDC balance is insufficient
- Rate limiting if too many calls are made in quick succession
- Newly launched protocols may not yet be covered
