Welcome to ZaFeed ("we", "us"). By creating an account, purchasing a market or calling the API, you agree to these Terms, as well as our Privacy Policy and Data Usage Agreement.
1. Services
- We provide market data APIs for exchanges worldwide: real-time quotes, historical K-lines (candlesticks), exchange snapshots (REST) and real-time streaming (WebSocket). See the developer docs for details.
- Services are subscribed by "market" (a country or region; forex and precious metals are each a separate market). Each market you subscribe to gets its own market Key, which can only access that market's data.
- Available markets and prices are listed on the Markets & Pricing page.
2. Account
- You need a valid email address to sign up, or you can sign in with a Google or GitHub account. Please use a real, working email address: it receives verification codes, payment and expiry reminders, ticket replies and other notices.
- You are responsible for keeping your password and market Keys safe. Actions and API calls made through your account or Keys are treated as your own. If you discover a leak, change your password or rotate the Key in the Member Center immediately.
- You can delete your account at any time under Settings in the Member Center. Deletion signs you out immediately and disables all market Keys; unexpired subscriptions are not refunded. How account data is handled is described in the Privacy Policy.
3. Pricing and payment
- Subscriptions run for 1, 3, 6 or 12 months, with 10% off quarterly, 15% off semi-annual and 20% off annual plans. There is no free trial and no account balance.
- We accept USDT on the TRC20 network only. Placing an order creates a payment request whose amount carries a unique decimal tail, used to identify your payment automatically. A payment request is valid for 30 minutes.
- Please send the exact amount shown on the payment request to the address shown on it. Transfers of a different amount are not activated automatically; open a ticket with the transaction hash and our support team will check it manually.
- We cannot recover funds sent on the wrong network (not TRC20), in the wrong currency or to the wrong address.
- Once your payment arrives, the subscription is activated or extended automatically. Renewals extend from the current expiry date and the Key stays the same.
4. Refunds
- Activated subscriptions are generally not refundable.
- In the following cases, please open a ticket and we will handle it after verification: duplicate payments or overpayments, or extended service unavailability caused by us. Refunds are calculated in proportion to the remaining time and returned in USDT to the original paying address, and the corresponding subscription time is deducted.
5. Acceptable use
- A market Key may only be used by you or your team. It may not be published, sold or lent to others.
- Each market Key has a WebSocket connection limit (1 by default; you can request a higher limit) and a request rate limit. Requests beyond these limits are rejected.
- You may not send requests intended to disrupt the service, or try to bypass authentication or rate limits, or access data that does not belong to you.
- How market data may be used is described in the Data Usage Agreement.
- If you violate these Terms, we may disable the relevant market Keys or account. In serious cases, no refund will be given.
6. Service availability
- We do our best to keep the service stable. Planned maintenance is announced in advance in News and shown as a notice at the top of the site.
- Market data comes from exchanges and other data sources and may be delayed, interrupted or incorrect. We fix issues as quickly as we can, but we do not guarantee that data is fully accurate, complete or uninterrupted.
7. Disclaimer
- Market data is for reference only and does not constitute investment advice. You are solely responsible for any trading or investment decisions made based on the data and their outcomes.
- To the extent permitted by law, we are not liable for indirect losses caused by data delays, errors or interruptions. Our liability is limited to the amount you actually paid for the relevant market in the 12 months before the issue occurred.
8. Changes to these Terms
When these Terms change, we update the date on this page, and important changes are announced in News or by email. Continuing to use the service after the changes take effect means you accept the updated Terms.
9. Contact us
If you have any questions about these Terms, please open a ticket in the Member Center, or contact support using the panel on the right side of the page.
