No need for EXPORT, we use these variables inside the script

CANARY_HASH="abcd1234"
CANARY_TOKEN="11a2222bb3333c444d555e6f777ggg88"
CANARY_IP_LIST="canary-ips-$(date +%Y-%m-%d).txt"

Date changes every midnight - putting it into a variable


# Query Canary API for all events, extract IPs, remove double quotes, and write to a text file for GreyNoise
curl https://$CANARY_HASH.canary.tools/api/v1/incidents/outside_bird/search -d auth_token=$CANARY_TOKEN -d node_ids="INSERT_NODE_IDS" -G | jq '.src_ips[] | .ip_address' | sed 's/\"//g' | cat > canary-ips-$(date +%Y-%m-%d).txt

--raw-output avoids double quotes - remove useless cat


# Read through each line of the text file, send each IP to the GreyNoise Community API for context, and write the results to a JSON file
file="canary-ips-$(date +%Y-%m-%d).txt"
lines=$(cat $file)

for line in $lines
while read -r ip_address
do
curl "https://api.greynoise.io/v3/community/$line" | jq '.' | cat >> GreyNoise-Canary-Threat-Intel-Report-$(date +%Y-%m-%d).json
done

curl "https://api.greynoise.io/v3/community/${ip_address}" | jq '.'
done < "${CANARY_IP_LIST}" > "GreyNoise-Canary-Threat-Intel-Report-$(date +%Y-%m-%d).json"
