SigmaGrid — Institutional Fair Value for Crypto Perpetual Markets

Public docs live now — Paid API launching Q1 2026

Traditional equity markets close at 4pm. Crypto synthetic equity perps trade 24/7.

Get institutional-grade fair value when Bloomberg terminals go dark.

SigmaGrid is the institutional fundamentals API for 24/7 synthetic-equity perpetuals such as SPY-PERP, QQQ-PERP, TSLA-PERP, and related synthetic-equity markets.

The 24/7 Fair Value Problem​

Crypto synthetic equity perpetuals trade around the clock across Hyperliquid, Avantis, Aevo, Drift, and Vertex. But institutional fundamentals only exist during market hours (9:30am-4pm ET, Mon-Fri).

At 2am on Sunday, what's the fair value of SPY-PERP?

  • Bloomberg Terminal: Offline
  • Institutional desks: Closed
  • Analyst coverage: Dark
  • Your trading bot: Flying blind

Without a fundamental anchor, you're trading against orderbook noise:

  • Overpay during thin liquidity
  • Miss mean-reversion opportunities
  • Get liquidated on event-driven moves
  • Can't distinguish rich vs cheap

Traditional markets have institutional infrastructure. Crypto perps have been guessing. Until now.

The Solution​

SigmaGrid supplies the missing institutional fundamentals layer.
We apply traditional equity derivatives models to crypto perpetual markets, providing the fundamental anchor that's been missing from DeFi.

We don't just show you orderbook prices. We tell you what the price should be.

We deliver them as clean, high-signal JSON API feeds designed from day one for AI agents.

  • Core mandatory fields are delivered in real-time per ticker.
  • Optional macro betas are available as a separate, higher-value layer.
  • Pricing is stablecoin denominated per request via x402 (no keys, no subscriptions).

API endpoints are scheduled to go live in Q1 2026. Until then, these docs define the schema, fields, and integration patterns so you can design agents and systems around SigmaGrid in advance.
