To upload a local file to the MetaID chain, specify the local file path and optional network parameters to forward the request to the upload script. The process returns a pinId and a fixed preview URL formatted as https://file.metaid.io/metafile-indexer/api/v1/files/content/<pinId>.

The maximum file size limit for on-chain uploads to MetaID is a hard limit of 20 MiB. Files larger than 2 MiB are automatically processed via chunked uploads, while files 2 MiB or smaller are uploaded directly.

Yes, the MetaID upload process supports specifying optional content-type parameters to control upload behavior. This ensures compatibility across different file types when uploading local files to the chain and retrieving the pinId.

You need to use chunked uploads for on-chain file storage when your local file exceeds 2 MiB in size. The upload mechanism automatically handles this chunked process for larger files up to the 20 MiB hard limit.

A local file upload to MetaID may fail before reaching the 20 MiB limit if the local file path is invalid. The upload mechanism validates the local file path before forwarding the request to the upload script.
