# Get Supply Caps

> Read collateral caps and current usage

Returns the market's global and per-borrower collateral caps alongside the collateral currently locked. Use this before quoting a borrower a size, since a loan that would push total collateral past `maxTotalCollateral` reverts at the contract.

All three values are formatted in the collateral token's own decimals.

## Path Parameters

<ParamField path="marketId" type="string" required>Market ID.</ParamField>

## Response Fields

<ResponseField name="data" type="object">
  <Expandable>
    <ResponseField name="maxTotalCollateral" type="string">Global cap across all borrowers. `0.0` means uncapped.</ResponseField>
    <ResponseField name="maxUserCollateral" type="string">Cap per borrower address. `0.0` means uncapped.</ResponseField>
    <ResponseField name="currentTotalCollateral" type="string">Collateral currently locked in the market.</ResponseField>
  </Expandable>
</ResponseField>

<Note>
  Returns `data: null` if the contract read fails. Both caps are set through [Update Market Config](/endpoints/external-securities-lending/update-config).
