Flagship endpoint
The Divergence Index. Nothing else like it.
/v1/divergence/current returns the real-time gap between what mainstream financial media (Bloomberg, Reuters, FT, WSJ) and crypto-native outlets (CoinDesk, The Block, HackerNews, Bluesky) are saying about the same market. That gap historically precedes price movements.
- → Mainstream vs crypto-native sentiment, measured separately
- → Gap expressed in percentage points — clear, actionable
- → Updated in real-time from 50+ classified sources
- → Historical divergence data for backtesting
- → No competing product offers this signal — full methodology →

FAQ
Common questions.
Is there a free trial?
Yes. Email our contact form mentioning “API trial” and we’ll send you a 7-day trial key with Developer-level access. No credit card required.
How is the Divergence Index calculated?
We classify 50+ sources into two tiers: mainstream financial media (Bloomberg, Reuters, FT, WSJ, AP) and crypto-native media (CoinDesk, The Block, HackerNews, Bluesky). Each article is analyzed by GPT-4 for sentiment and signal strength. The gap between the two groups’ weighted sentiment scores — expressed in percentage points — is the Divergence Index. It updates in real time as new articles are processed.
How do I authenticate API requests?
All requests require a
X-HafidWatch-Key header with your API key. Keys are generated after subscription and sent to your email. Full documentation is available at api.hafidwatch.com/docs.What’s the uptime SLA?
Pro and Enterprise plans include a 99.5% uptime SLA. Developer and Starter plans operate on a best-effort basis — in practice the API runs 24/7 on the same infrastructure as our main publishing pipeline.
Can I use the data commercially?
Yes. All plans include commercial use rights. If you need a white-label arrangement — embedding the data under your own brand — that’s available on the Enterprise plan.
When does the API launch?
Public launch is October 28, 2026. You can request early access now via our contact form — trial keys are available before the official launch date.
