An API key is required to connect to the Pinata API. The key serves as a unique identifier for authentication and authorization. You can generate an API key following the steps outlined in this guide.

This error usually occurs when something unexpected is included with the API request. To resolve this issue:

Verify that you are following the correct API schema as described in the Pinata API docs. Watch for spelling errors, unknown characters, or invalid capitalization, e.g., “Files” instead of “files”

Examine your files. If you are including more than one file with the request, special handling is required, especially for folder uploads.

The Pinata API has a rate limit of 180 requests per minute, which aligns with web3 industry standards. Although we do not increase this limit, you can implement a bottlenecking mechanism in your code to manage the traffic.

For details on how to upload a directory or folder via the API, please refer to the relevant section in our documentation.

Currently, we do not offer a feature for exporting all the IPFS CIDs out of a folder directly. However, you can use third-party IPFS tools like the IPFS Desktop app or IPFS CLI. If you need a complete list of your CIDs, our API provides this information. For more details, visit this link.

We do not offer domain-based restrictions on our API as it is not designed for front-end usage; doing so would expose your API keys. We recommend utilizing the API in a backend environment for security reasons.
