How do I upload a zip with the API?

FILE=storefront.zip
SIZE=$(wc -c < $FILE | tr -d ' ')
UP=$(curl -s $CB/v1/buckets/BUCKET_ID/uploads \
  -H "Authorization: Bearer $CLATTER_API_KEY" -H "X-Clatter-Account: $CLATTER_ACCOUNT_ID" \
  -H "Content-Type: application/json" -d "{\"name\": \"$FILE\", \"size\": $SIZE}" | jq -r .id)

split -b 16777216 -d -a 5 $FILE part-
i=0
for p in part-*; do
  curl -s -X PUT $CB/v1/uploads/$UP/chunks/$i \
    -H "Authorization: Bearer $CLATTER_API_KEY" -H "X-Clatter-Account: $CLATTER_ACCOUNT_ID" \
    -H "Content-Type: application/octet-stream" --data-binary @$p > /dev/null
  i=$((i+1))
done

curl -s -X POST $CB/v1/uploads/$UP/complete \
  -H "Authorization: Bearer $CLATTER_API_KEY" -H "X-Clatter-Account: $CLATTER_ACCOUNT_ID"

$CB is https://api.codebuckets.clatterlabs.xyz. The key needs buckets:write. Python and JavaScript versions are in the Quickstart.
