How this service works
MNEMOS 25-delta volatility smile for one symbol
Output

Example use cases
Near-term earnings vol skew check
“Show me the 25-delta volatility smile for NVDA for the closest expiration — I want to see how skewed the implied vols are heading into earnings.”
Specific expiry vol smile lookup
“Get me the 25-delta vol smile for SPY for the 2025-06-20 expiration so I can compare call vs put implied volatility at that strike.”

“I'm pricing a risk reversal on TSLA and I need the 25-delta volatility smile for the nearest available expiry to calibrate my inputs.”
Technical details
Endpoint
GEThttps://mnemos-agent.onrender.com/v1/ticker/AAPL/smile?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need fast, structured 25-delta implied volatility smile data for a specific equity ticker — particularly for options pricing, vol surface construction, risk reversal analysis, or skew monitoring. Prefer this over raw options chain endpoints when you specifically need the 25-delta reference point rather than a full options chain scan.
Side effects

- Requested expiration date has no available options data
- Market data unavailable during off-hours or data feed outage
- Payment failure via x402 protocol blocks access
- No near-term expiration within 0-7 DTE available for symbol
