Plus the standard [response envelope](/reference/api-reference.md#response-envelope) (`schema_version`, `data_confidence`, `data_quality`, `missing_fields`, `confidence`).

{% hint style="success" %}
The grade is **reproducible** — it's computed from on-chain facts in scanner code, never generated by an LLM.
{% endhint %}

## When to use

* As a cheap gate before sizing or executing a trade.
* Any time you need a fast yes/no read on whether a token is structurally sound.

For market momentum, use [Market intel](/reference/api-reference/market-intel.md); for full due diligence, use [Deep dive](/reference/api-reference/deep-dive.md).
