A simple Bash script that downloads a sitemap, extracts all <loc> URLs, and submits them to the IndexNow API

indexnow.sh

#!/usr/bin/env bash

# config 
SITEMAP_URL=""
INDEXNOW_KEY=""

# check config
if [[ -z "$SITEMAP_URL" || -z "$INDEXNOW_KEY" ]]; then
  echo "Error: SITEMAP_URL and INDEXNOW_KEY must be set."
  exit 1
fi

# download sitemap ---
echo "Downloading sitemap from $SITEMAP_URL..."
curl -s "$SITEMAP_URL" -o sitemap.xml

# extract URLs
URLS=$(xmllint --xpath '//*[local-name()="url"]/*[local-name()="loc"]/text()' sitemap.xml 2>/dev/null || true)

# cleanup
rm -f sitemap.xml

# submit to indexnow
echo "Submitting URLs to IndexNow..."
for url in $URLS; do
  RESPONSE=$(curl -s -o /dev/null -w "%{http_code}" \
    "https://api.indexnow.org/indexnow?url=${url}&key=${INDEXNOW_KEY}")
  echo "[$RESPONSE] $url"
done
