<p>Actually, you can't get bids information from blockchain itself.
Since those information are on marketplace smart contract (Jpg.store).</p>
<p>But you can get these information using some provided API.</p>
<p>For example, you can use api which is provided by CNFT.TOOLS.</p>
<p><a href="https://cnft.tools/" rel="nofollow noreferrer">https://cnft.tools/</a></p>
<p>Here is example of api.</p>
<p><a href="https://api.cnft.tools/api/external/$%7BpolicyId%7D/" rel="nofollow noreferrer">https://api.cnft.tools/api/external/${policyId}/</a></p>
<p>This api will give you the current price, and whether nfts are on sale or not, and their metadata, etc...</p>
<p>Hope this will help you.</p>

<p>We're building a marketplace for cardano and we're aware that the owned tokens/nfts can be fetched via the getBalance() function. How do we get the bids or lists (for sale) for a particular owner address? Is this stored and decoded somewhere in the blockchain much like the owned nfts? THanks</p>

Actually, you can't get bids information from blockchain itself.
Since those information are on marketplace smart contract (Jpg.store).

But you can get these information using some provided API.

For example, you can use api which is provided by CNFT.TOOLS.

<https://cnft.tools/>

Here is example of api.

[https://api.cnft.tools/api/external/${policyId}/](https://api.cnft.tools/api/external/$%7BpolicyId%7D/)

This api will give you the current price, and whether nfts are on sale or not, and their metadata, etc...

Hope this will help you.
