Right now I have some NFTs to pin on the blockfrost IPFS. That way I don't need to run the node 24h a day. But for some reason the API returns an error when I try to add new assets.
I'm using a free account and have used 0/100mb so far. I used that before and it worked but now it doesn't anymore.
This is the endpoint I'm using:
curl "https://ipfs.blockfrost.io/api/v0/ipfs/add" \ -X POST \ -H "project_id: $PROJECT_ID" \ -F "file=@./README.md"
The file I want to upload is a zip with a few KB, so not a big thing.
The error is an invalid project key, support says I need an IPFS key but I don't know how to obtain that.
