# Pricing: Compare Free, Starter, Pro, and Quant Plans
> Compare CS2Cap's 4 API tiers — Free, Starter, Pro, and Quant — by monthly request quota, rate limits, endpoint access, and feature availability.
CS2Cap offers four API tiers to fit every use case, from quick evaluation to production-scale analytics:
* **Free** gives you immediate access to **Live Prices + 30d of OHLCV data** at no cost,
* **Starter** adds **Live Buy Orders, Batch Queries + Higher Limits** for serious hobbyists,
* **Pro** unlocks the **Prices + Bids + Sales + History** endpoints for full visibility across the market,
* **Quant** enables **Advanced Analytics, Arbitrage Scanner + Webhook Support**
Every tier is backed by the same 40-marketplace data network with 5–10 min freshness and all basic utility endpoints documented [here](/api-reference/catalog).

## API key rules

* **Quant supports child keys.** Quant accounts can create up to 25 child keys for sub-leasing. Each child key supports optional per-key quota and rate-limit caps.
## Included on every tier
Every plan — including Free — ships with the full breadth of CS2Cap's data network:
* **40 supported marketplaces**, including BUFF163, Youpin898, C5, CSFloat, GameBoost, Skinport, DMarket, Waxpeer, Bitskins, Haloskins, Market.csgo, Tradeit, and more.
* **Doppler phase differentiation** in prices, buy orders, and recent sales whenever the underlying marketplace exposes phase data.
* **5–10 minute data freshness** across most providers. Prices and bids are cached for fast, consistent responses.
* **Stable, machine-readable error codes** on every error response.
* **Consistent minor-unit pricing** for all monetary values — for example, `2550` represents `$25.50`.
## Billing
Paid tiers are billed monthly through Stripe via card, or NOWPayments via cryptocurrency.
* **Upgrades** take effect immediately and are prorated on the current invoice.
* **Downgrades** take effect at the start of the next billing cycle. Until then, you retain your current tier's access.
* **Payment failures** keep or return your account to the Free tier until the payment processor resolves the retry. No data is lost.
* **Cancellation** can be done at any time through the Stripe customer portal. A cancelled subscription stays active until the end of the current billing cycle, then reverts to Free. Subscriptions paid through cryptocurrencies do not renew automatically and cannot be cancelled before the end of the billing period.
## FAQ
Yes. Upgrades are immediate and prorated against the current billing period. Downgrades take effect at the end of the current billing cycle and can be reversed before then.
Further requests return `429 RATE_LIMIT_MONTHLY_QUOTA_EXCEEDED` until the next billing period begins. Per-minute rate limit violations return `429 RATE_LIMIT_EXCEEDED` with a `Retry-After` header indicating how long to wait.
Yes. Pro and Quant include up to one year of per-item daily OHLCV history through [`GET /prices/candles`](/api-reference/prices#get-/prices/candles-—-price-candles-ohlcv). Granular per-provider history goes back up to 35 days through [`GET /prices/history`](/api-reference/prices#get-/prices/history-—-price-history).
You can browse the provider catalog on every tier, but Free is limited to current prices from [`GET /prices`](/api-reference/prices#get-/prices-—-list-prices). Starter adds current bids and 100-item batch lookups, but not sales, history, analytics, listing URLs, or NDJSON snapshots.
