Why QuantOracle?
**Every financial agent needs math. QuantOracle is that math.**
- **63 pure calculators** across options, derivatives, risk, portfolio, statistics, crypto/DeFi, FX/macro, and TVM
- **10 composite workflows** that bundle 5-15 calculator calls (backtest strategies, rebalance planning, options strategy selection, hedging recommendations, full risk analysis, pairs signals, and more)
- **Zero dependencies** for the 73 calculators + composites -- no market data, accounts, or third-party APIs; send numbers in, get numbers out
- **QuantOracle Live (new)** -- a separate paid tier that *brings* the data: fresh crypto volatility (/v1/live/volatility) and perp funding rates (/v1/live/funding-rates). We fetch the live market data and run the math, so your agent doesn't have to. 20 free calls/IP/day to evaluate, then pay-per-call via x402.
- **QuantOracle Watch (new)** -- 24/7 position monitoring: register a crypto perp position once and get HMAC-signed webhooks on funding-adjusted liquidation distance, funding flips, and vol-regime changes — re-checked every 60 seconds. Free 48h trial; $5 per position per 30 days via x402.
- **Deterministic** -- the calculators always produce the same outputs for the same inputs, so agents can cache, verify, and chain calls
- **Citation-verified** -- every formula tested against published textbook values (Hull, Wilmott, Bailey & Lopez de Prado)
- **120 accuracy benchmarks** passing with analytical solutions
- **Fast** -- sub-millisecond to 70ms compute time per call
- **Free tier** -- 1,000 calls/IP/day, no API key, no signup, zero friction
QuantOracle is designed to be called repeatedly. An agent running a backtest might call 10+ endpoints per iteration. That's the model -- be the calculator agents reach for every time they need quant math.
Why not just let the LLM do the math?
| | QuantOracle | LLM in-context math |
|---|---|---|
| **Accuracy** | Exact (analytical formulas) | 70-85% on complex math |
| **Determinism** | Same input = same output, always | Different every run |
| **Speed** |
