# CRYPTYX IV Surface

> CRYPTYX IV Surface is a paid API for AI agents from www.cryptyx.ai, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-13).

Returns the implied-volatility surface (expiry × strike grid with IV, delta, and gamma) for a given crypto asset from Deribit options data.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability cryptyx-iv-surface-60ab4892
```

Example prompt: Pull the current Deribit implied-volatility surface for BTC — I need the full expiry-by-strike grid with IV, delta, and gamma so I can read the skew and price a risk reversal.

## When to prefer this

Choose this endpoint when you need a structured, machine-readable implied-volatility surface for a crypto asset — specifically when doing options structuring, vol skew analysis, risk-reversal pricing, or delta/gamma reads across the full expiry × strike grid. Prefer over generic market data endpoints when Deribit options surface data is required.

## Known failure modes

- Missing or invalid asset symbol returns a 400 or validation error
- Asset not supported on Deribit returns an empty surface or 404
- Rate limiting or payment failure (x402) returns a 402 Payment Required
- Deribit data unavailable or stale returns a 503 or partial surface
- Malformed query parameter returns a schema validation error

## How this service works

CRYPTYX | institutional-grade crypto intelligence: 150+ signals, 440+ metrics, 200+ assets. | Latest-day Deribit IV term structure for one asset plus current put/call open-interest ratio. Returns term_structure (per-tenor rows: tenor, atm_iv, rr_25d 25-delta risk reversal, bf_25d 25-delta butterfly, iv_25c, iv_25p), pcr block (pcr, oi_put, oi_call), and asof_day. Coverage limited to Deribit venues (BTC, ETH) — out-of-scope assets return empty arrays. Raw upstream telemetry feeding the OPT factor class; use for skew reads, vol-term structuring, and options positioning context.

## Output

A JSON object containing the asset symbol and an array of surface nodes, each with expiry date, strike price, implied volatility (IV), delta, and gamma — forming a complete options vol surface grid.
