Pricing that feels like a mistake

Yes — 100,000 requests every month, forever, no credit card. And it is the same data quality as every paid plan: full financial statements, complete price history, all 363+ endpoints. We can afford it because data has zero marginal cost. The catch you are looking for does not exist — the free tier is for personal and non-commercial use, and volume is the only limit.

Every paid subscription started now keeps its price forever. When we raise prices later — and we will — founding customers are grandfathered at today's rate for as long as they stay subscribed. Early believers should be rewarded, not repriced.

One HTTP call = one request. Batch endpoints let you query multiple symbols in a single call (counted as 1 request). Failed requests (4xx, 5xx) and cached responses do not count against your included quota.

Paid plans include a monthly request quota. If you exceed it, additional requests are billed automatically at your plan's overage rate per 1,000 requests — $1.50 on Builder, $0.80 on Startup, $0.30 on Scale. Usage is aggregated monthly and overage appears on your next invoice. The free tier has a hard limit instead: you can never be surprise-billed.

Yes. Upgrade or downgrade instantly, cancel in one click — no sales call, no retention flow. When upgrading mid-cycle, you pay the prorated difference. When downgrading, the remaining balance is credited to your account.

Yes. Annual billing saves you 2 months compared to monthly — available on Builder, Startup, and Scale plans.

Limits are monthly request quotas, not per-second throttles. Free tier has standard burst limits, Builder and Startup progressively higher ones, Scale has no rate limits at all.

The free tier includes end-of-day data and delayed quotes. All paid plans get real-time market data. Fundamentals, estimates, and filings update as they are published — identical on every tier.

Free tier requires attribution ("Data by Eulerpool") in any public-facing product. Paid plans (Builder, Startup, Scale) include full commercial usage rights with no attribution required.

Yes — completely. Students, PhD candidates, and academic researchers get the Startup tier (10M requests/month) free. Email michael@eulerpool.com from your university address with one line about your research and we'll switch your account on, usually the same day.

Startup plans include a 99.9% uptime SLA. Scale plans include a 99.99% SLA with dedicated support. Custom SLAs with credits are available for Enterprise agreements.

Credit card (Visa, Mastercard, Amex) for self-serve plans. Scale and Enterprise plans support wire transfer, ACH, and purchase orders.

Enterprise covers custom request volume beyond 50M/month, real-time feeds, dedicated delivery (API, SFTP, S3, Snowflake), point-in-time data for backtesting, AI/LLM licensing for training and retrieval, custom SLAs with credits, and a named account manager. Pricing is quoted per agreement, billed annually via wire transfer, ACH, or purchase order. Contact sales for a proposal within 48 hours.
