# blend_check_rates — View Current Blend Pool APY Rates

> Returns the current supply APY for every configured Blend pool. Read-only — no funds move. Useful for yield monitoring and pre-payment liquidity checks.

`blend_check_rates` gives your agent a read-only view of the current supply APY for each Blend pool that Nebula is configured to use. No funds are moved — it is a pure data query. Use it to understand what yield rate your idle treasury funds are earning, or to evaluate whether conditions are favorable before a large deposit.

## Parameters

This tool takes no parameters.

## Response

An array of pool rate objects, one per configured Blend pool.

<ResponseField name="pool_id" type="string">
  The unique on-chain identifier of the Blend pool.
</ResponseField>

<ResponseField name="asset" type="string">
  The asset being supplied to the pool (e.g. `USDC`).
</ResponseField>

<ResponseField name="supply_apy" type="number">
  Current annualised supply yield for this pool, expressed as a percentage (e.g. `4.72` means 4.72% APY).
</ResponseField>

## When to use

* **Before a large payment** — confirm that funds currently in Blend are earning yield and note how long it may take for an auto-rebalance to make them liquid.
* **Yield monitoring** — poll periodically to track how APY changes across pools.
* **Choosing a pool** — if your dashboard is configured for multiple pool targets, compare rates here before triggering a rebalance from the Nebula dashboard.

<Note>
  `blend_check_rates` is read-only. To actually deposit or withdraw from Blend, use `blend_deposit` or `blend_withdraw` from the Nebula dashboard — those tools are not available to agent tokens.
</Note>
