How do I authenticate with the Otis API?

Pass your API key via the X-API-Key header with every request. Generate your key instantly from the dashboard at app.otisfinance.com — no credit card required for the free tier (5 req/min).

How fresh is the Otis market data?

Price data is updated daily after market close (typically by 8 PM ET). Financial statements are updated as new filings are published. SEC filings (10-K, 10-Q, 8-K, Form 4) are indexed within hours of publication.

Which stock tickers does Otis support?

Otis currently covers US equities listed on NYSE and NASDAQ. Coverage is actively expanding — check the documentation for the latest supported ticker list. All 34 endpoints work consistently across supported tickers.

What are the Otis API rate limits?

Rate limits scale by plan: Free allows 5 requests per minute with a 100 requests/day cap, Starter ($99/mo) allows 1,000 requests per minute with no daily cap, and Pro ($999/mo) has unlimited rate limits. Rate limit headers (X-RateLimit-Limit, X-RateLimit-Remaining, X-RateLimit-Reset) are included in every response.

Can I use Otis for commercial projects?

Commercial use requires a Pro plan ($999/mo) or above. The Pro tier includes a commercial license to build and ship trading bots, financial dashboards, SaaS products, AI agents, or quantitative models. Free and Starter tiers are for personal use only.

How far back does historical stock data go?

Historical depth depends on your plan: Free tier includes 1 year of daily OHLCV data, Starter includes 5 years, and Pro provides the full 20+ years of history.

What response formats does Otis support?

All endpoints return structured JSON by default with a consistent envelope (ticker, data, meta). You can also request CSV with ?format=csv and select specific fields with ?fields=time,close,volume to reduce payload size.

How does pagination work in the Otis API?

All list endpoints support cursor-based pagination. Responses include a nextCursor value in the meta object — pass it as ?cursor= on the next request. This is more reliable than offset pagination for time-series data.

Are SDKs available for the Otis API?

Official SDKs for Python, TypeScript, Go, Ruby, and Java are currently under development. In the meantime, you can call the REST API directly with cURL or any HTTP client — every endpoint is fully documented with request and response examples.

Is there an uptime SLA for the Otis API?

Otis targets 99.9% uptime. The API runs on Cloudflare Workers, deployed globally at the edge with sub-100ms P99 response times. Real-time service status is available at status.otisfinance.com.
