Cloudflare API

Hit the Cloudflare REST API directly when wrangler CLI or MCP servers aren't the right tool. For bulk operations, fleet-wide changes, and features that wrangler doesn't expose.

When to Use This Instead of Wrangler or MCP

| Use case | Wrangler | MCP | This skill | |----------|---------|-----|-----------| | Deploy a Worker | Yes | Yes | No | | Create a D1 database | Yes | Yes | No | | Bulk update 50 DNS records | Slow (one at a time) | Slow (one tool call each) | Yes — batch script | | Custom hostnames for white-label | No | Partial | Yes | | Email routing rules | No | Partial | Yes | | WAF/firewall rules | No | Yes but verbose | Yes — direct API | | Redirect rules in bulk | No | One at a time | Yes — batch script | | Zone settings across 20 zones | No | 20 separate calls | Yes — fleet script | | Cache purge by tag/prefix | No | Yes | Yes (when scripting) | | Worker route management | Limited | Yes | Yes (when bulk) | | Analytics/logs query | No | Partial | Yes — GraphQL | | D1 query/export across databases | One DB at a time | One DB at a time | Yes — cross-DB scripts | | R2 bulk object operations | No | One at a time | Yes — S3 API + batch | | KV bulk read/write/delete | One at a time | One at a time | Yes — bulk endpoints | | Vectorize query/delete | No | Via Worker only | Yes — direct API | | Queue message injection | No | Via Worker only | Yes — direct API | | Audit all resources in account | No | Tedious | Yes — inventory script |

Rule of thumb: Single operations → MCP or wrangler. Bulk/fleet/scripted → API directly.

Auth Setup

API Token (recommended)

Create a scoped token at: Dashboard → My Profile → API Tokens → Create Token

# Store it
export CLOUDFLARE_API_TOKEN="your-token-here"

# Test it
curl -s "https://api.cloudflare.com/client/v4/user/tokens/verify" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" | jq '.success'

Token scopes: Always use minimal permissions. Common presets:

"Edit zone DNS" — for DNS operations
"Edit zone settings" — for zone config changes
"Edit Cloudflare Workers" — for Worker route management
"Read analytics" — for GraphQL analytics

Account and Zone IDs

# List your zones (find zone IDs)
curl -s "https://api.cloudflare.com/client/v4/zones?per_page=50" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" | jq '.result[] | {name, id}'

# Get zone ID by domain name
ZONE_ID=$(curl -s "https://api.cloudflare.com/client/v4/zones?name=example.com" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" | jq -r '.result[0].id')

Store IDs in environment or a config file — don't hardcode them in scripts.

Workflows

Bulk DNS Operations

Add/update many records at once (e.g. migrating a domain, setting up a new client):

# Pattern: read records from a file, create in batch
while IFS=',' read -r type name content proxied; do
  curl -s -X POST "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/dns_records" \
    -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
    -H "Content-Type: application/json" \
    -d "{\"type\":\"$type\",\"name\":\"$name\",\"content\":\"$content\",\"proxied\":$proxied,\"ttl\":1}" \
    | jq '{name: .result.name, id: .result.id, success: .success}'
  sleep 0.25  # Rate limit: 1200 req/5min
done < dns-records.csv

Export all records from a zone (backup or migration):

curl -s "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/dns_records?per_page=100" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  | jq -r '.result[] | [.type, .name, .content, .proxied] | @csv' > dns-export.csv

Find and replace across records (e.g. IP migration):

OLD_IP="203.0.113.1"
NEW_IP="198.51.100.1"

# Find records pointing to old IP
RECORDS=$(curl -s "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/dns_records?content=$OLD_IP" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" | jq -r '.result[].id')

# Update each one
for RECORD_ID in $RECORDS; do
  curl -s -X PATCH "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/dns_records/$RECORD_ID" \
    -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
    -H "Content-Type: application/json" \
    -d "{\"content\":\"$NEW_IP\"}" | jq '.success'
done

Custom Hostnames (White-Label Client Domains)

For SaaS apps where clients use their own domain (e.g. app.clientdomain.com → your Worker):

# Create custom hostname
curl -s -X POST "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/custom_hostnames" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "hostname": "app.clientdomain.com",
    "ssl": {
      "method": "http",
      "type": "dv",
      "settings": {
        "min_tls_version": "1.2"
      }
    }
  }' | jq '{id: .result.id, status: .result.status, ssl_status: .result.ssl.status}'

# List custom hostnames
curl -s "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/custom_hostnames?per_page=50" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  | jq '.result[] | {hostname, status, ssl_status: .ssl.status}'

# Check status (client needs to add CNAME)
curl -s "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/custom_hostnames/$HOSTNAME_ID" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" | jq '.result.status'

Client setup: They add a CNAME: app.clientdomain.com → your-worker.your-domain.com

Email Routing Rules

# Enable email routing on zone
curl -s -X PUT "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/email/routing/enable" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN"

# Create a routing rule (forward info@ to a real address)
curl -s -X POST "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/email/routing/rules" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Forward info@",
    "enabled": true,
    "matchers": [{"type": "literal", "field": "to", "value": "info@example.com"}],
    "actions": [{"type": "forward", "value": ["real-inbox@gmail.com"]}]
  }' | jq '.success'

# Create catch-all rule
curl -s -X POST "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/email/routing/rules" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "Catch-all",
    "enabled": true,
    "matchers": [{"type": "all"}],
    "actions": [{"type": "forward", "value": ["catchall@company.com"]}]
  }' | jq '.success'

# List rules
curl -s "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/email/routing/rules" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" | jq '.result[] | {name, enabled, matchers, actions}'

Cache Purge

# Purge everything (nuclear option)
curl -s -X POST "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/purge_cache" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"purge_everything": true}'

# Purge specific URLs
curl -s -X POST "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/purge_cache" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"files": ["https://example.com/styles.css", "https://example.com/app.js"]}'

# Purge by cache tag (requires Enterprise or cache tag headers)
curl -s -X POST "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/purge_cache" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"tags": ["product-123", "homepage"]}'

# Purge by prefix
curl -s -X POST "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/purge_cache" \
  -H "Authorization: Bearer $CLOUDFLARE_API_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"prefixes": ["https://example.com/images/"]}'

Redirect Rules (Bulk)

# Create a redirect rule
curl -s -X POST "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/rulesets/phases/http_request_dynamic_redirect/entrypoint" \
  -H "Authorization: Be
