Data API Terms of Service

Last updated: April 4, 2026

1. Definitions

"Data API" refers to the DepthSignals structured data endpoints at depthsignals.com/v1/data/*, including REST and WebSocket interfaces.

"Data" refers to all information delivered through the Data API, including but not limited to: structural levels, liquidity events, zone events, regime shifts, confluence-scored signals, and pattern performance statistics.

"Subscriber" refers to any individual or entity that holds an active API key.

2. License Grant

DepthSignals grants Subscriber a non-exclusive, non-transferable, revocable license to access and use the Data for the Subscriber's own internal purposes, subject to these terms and the Subscriber's active tier.

3. Prohibited Uses

Subscriber shall NOT:

1. Reverse engineer scoring algorithms, confluence formulas, quality gates, or any proprietary methodology from API output.
2. Redistribute, resell, or sublicense the Data to any third party, whether in raw or processed form.
3. Create derivative works that reproduce, replicate, or approximate DepthSignals' scoring methodology.
4. Systematically probe API endpoints to infer internal thresholds, weights, or detection parameters (e.g., correlating inputs/outputs to reverse scoring functions).
5. Use the Data to build a competing signal service, data product, or trading system that replicates DepthSignals' methodology.
6. Embed API keys in client-side code (browser JavaScript, mobile apps) where they can be extracted by third parties.
7. Share API keys with unauthorized users or use a single key across multiple organizations.
8. Exceed rate limits or circumvent access controls through distributed requests, key rotation, or other means.

4. Intellectual Property

All Data, scoring methodologies, detection algorithms, pattern libraries, and the underlying proprietary architecture remain the exclusive intellectual property of DepthSignals. No ownership or IP rights are transferred through API access.

The Data is provided as processed output. The proprietary methods used to generate this output — including confluence scoring formulas, zone qualification gates, event detection thresholds, and pattern conditions — are trade secrets protected under applicable law.

5. Data Accuracy & Disclaimer

The Data is provided "as is" without warranty of any kind. DepthSignals does not guarantee the accuracy, completeness, or timeliness of any data delivered through the API.

The Data does not constitute financial advice. Trading involves substantial risk. Subscriber is solely responsible for any trading decisions made using the Data.

Past performance of signals, patterns, or strategies does not guarantee future results.

6. Rate Limits & Fair Use

API access is subject to per-minute and per-day rate limits as specified in the API documentation. Sustained abuse may result in temporary or permanent key revocation without refund.

7. Monitoring & Audit

DepthSignals reserves the right to monitor API usage patterns to detect potential reverse engineering, redistribution, or terms violations. Usage data (request counts, endpoints accessed, timing patterns) is logged for this purpose.

API responses may contain per-client watermarks for data provenance tracking. Attempts to remove or circumvent watermarking constitute a terms violation.

8. Termination

DepthSignals may revoke API access immediately upon discovery of terms violations, without prior notice or refund. Subscriber may terminate access at any time by revoking their API keys.

Upon termination, Subscriber must delete all cached or stored Data obtained through the API within 30 days.

9. Limitation of Liability

In no event shall DepthSignals be liable for any indirect, incidental, special, or consequential damages arising from the use or inability to use the Data API, including but not limited to trading losses, lost profits, or data loss.

DepthSignals' total liability shall not exceed the fees paid by Subscriber in the 3 months preceding the claim.

10. Governing Law

These terms shall be governed by and construed in accordance with applicable law. Disputes shall be resolved through binding arbitration.

11. Modifications

DepthSignals reserves the right to modify these terms at any time. Continued use of the API after modification constitutes acceptance of the updated terms. Material changes will be communicated via email to active Subscribers.
