    export FATCAT_API_HOST=https://api.fatcat.wiki
    export FATCAT_AUTH_WORKER_CLEANUP=[...]
    export FATCAT_API_AUTH_TOKEN=$FATCAT_AUTH_WORKER_CLEANUP

    fatcat-cli search file domain:isiarticles.com --entity-json -n0 \
        | rg -v '"content_scope"' \
        | rg 'isiarticles.com/' \

    fatcat-cli search file domain:isiarticles.com '!content_scope:*' --entity-json -n0 \
        | rg -v '"content_scope"' \
        | rg 'isiarticles.com:80/' \
