Developers · v1 Stable

Institutional financial analytics, by API or AI agent.

Deterministic compute for fixed income, options, and portfolios. Bond pricing, BSM Greeks, Monte Carlo VaR, equity DCF — exposed as a REST API and as an MCP server for Claude, Cursor, and any MCP-compatible client. Free tier: 100 calls/day, no credit card.

── Two Surfaces, One Engine

For developers and AI agents alike.

REST API

Drop into any backend, notebook, or cron job. Bearer-token auth, JSON in/out, X-RateLimit headers, semver-stable v1.

  • ›17 endpoints across compute, rates, FX, equities, filings
  • ›QuantLib-parity numerics (1e-6 on bond pricing, 1e-8 on BSM)
  • ›Free 100/day · Plus 1k/day · Pro 10k/day
View REST reference
MCP Server

One npx command exposes every tool to Claude Desktop, Cursor, Continue, or any MCP-compatible host. No agent framework needed.

  • ›Eight tools today — bond pricing, scenarios, BSM, VaR, DCF
  • ›Same compute as the REST API, no shadow implementations
  • ›Read-only and idempotent — safe for autonomous agents

Working examples. Copy, paste, run.

These curls use the public demo key. They work right now — no signup required. Demo key is rate-limited per IP and restricted to compute and rates endpoints.

Solve YTM from a clean price (or vice versa) and get duration, convexity, DV01, and accrued interest. Day-count aware (30/360, ACT/ACT, ACT/360, ACT/365F).

── Why Strata

Compute that LLMs can't fake.

Fixed-income depth

Polygon, Alpaca, FMP all skim the bond surface. Strata goes deep: YTM/YTC/YTW solvers, callable & putable bonds, day-count-aware accrued, bundled historical scenarios, KRD across the whole curve.

Deterministic — not generated

Every endpoint is real numerical code, not an LLM dressed up as math. Bisection solvers, Cholesky-decomposed VaR, exact day-count fractions. Same answer every time, to the basis point.

Institutional rigor

~256 numerical-parity assertions in CI, anchored against QuantLib closed-form benchmarks. 1e-6 tolerance on bond pricing. 1e-8 on BSM Greeks. We publish the methodology — no black boxes.

── FAQ

Common questions.

The demo key (sk_strata_demo_*) is rate-limited to 50 calls per day per IP and only works against compute and rates endpoints — not equity market data. Use it to test the API end-to-end before signing up for a real key. We rotate it periodically; if you hit a 401 with this key, that's why.
