Zerion’s API includes a built-in spam detection system that flags low-quality or deceptive assets using the is_trash flag. This enables developers to filter out spam tokens across endpoints like /positions and /transactions.
To determine whether a token is spam, we use a combination of methods:
- Heuristics: We analyze on-chain behaviors such as mass airdrops, impersonation of popular assets (e.g., mimicking name/symbol), and suspicious transfer patterns.
- External Intelligence: We leverage multiple third-party data providers to assess token quality.
- Community Feedback: Users and partners can report false positives or unflagged spam tokens. These are reviewed and reflected in updates to our spam list.
- Internal Rules: We apply proprietary logic in different parts of the system (e.g., transaction labeling, portfolio display) to ensure consistent spam filtering across APIs and frontend views.
If you notice an asset that’s incorrectly flagged or missing a flag, reach out via our support chat or email us at [email protected]. We actively refine the filter based on evolving behavior and ecosystem feedback.
While some platforms rely solely on liquidity thresholds to guide filtering decisions, we believe proactive spam detection offers a better user experience, especially for wallets and explorers focused on clarity, safety, and trust.
