How this service works
Pay-per-call (x402) market-data + research API for autonomous agents. Paid endpoints return HTTP 402 with an x402 v2 payment challenge; pay in USDC on Base with any x402-aware client.
Output
Returns a JSON envelope containing the implied volatility surface, likely including vol values across strikes (delta or moneyness) and expiry dates, representing the market's current pricing of future realized volatility in options markets.
Example use cases
Options pricing for DeFi agent
“Fetch the latest implied volatility surface in JSON so I can plug it into my options pricing model and get fair values for at-the-money and out-of-the-money contracts.”
Real-time vol skew monitoring
“Grab the current vol surface data and tell me if the skew looks unusually steep compared to a flat term structure — I want to know if the market is pricing in tail risk.”
Automated derivatives research report
“Pull the latest volatility surface and summarize the shape of the term structure and skew so I can include it in my weekly crypto derivatives research brief.”
Technical details
Endpoint
GEThttps://api.sundayfactoryx.com/v1/market/vol/surface?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need programmatic, pay-per-call access to implied volatility surface data for autonomous agents, especially when operating in an x402 micropayment environment on Base. Ideal for derivatives pricing engines, risk models, or research pipelines that require fresh vol surface snapshots without a subscription commitment.
Side effects
- HTTP 402 returned when no x402 payment is attached — client must complete USDC payment challenge on Base before retrying
- Invalid format parameter may result in malformed or unexpected response structure
- Network or upstream data feed outage may return 5xx errors
- Stale or unavailable market data may result in empty or incomplete vol surface payload
