◈ DEFI-VISION · Open Data
Every event we capture. Free. CC0.
Defi-Vision runs depeg + MEV detection pipelines on Solana 24/7. The raw events are published weekly here under CC0 1.0 Universal — no auth, no API key, no rate limit beyond a 24-hour edge cache. Use them in research, dashboards, bots, academic papers. Attribution is appreciated but not required.

Limits and caveats
- Each weekly dump caps at 50,000 events. Real-world weeks have been well under this.
- The current week is a moving target — events captured after the edge cache populates take up to 24h to appear.
- Completed weeks are immutable — once an ISO week ends, the dump for that week never changes.
- Event schemas may evolve. Old dumps stay readable; new fields appear additively.
- For real-time access (sub-minute), use the authenticated v1 API or webhooks at /developers.
