PUT /v1/sites/{siteId}/cdn/security
Change a site's CDN security and bot settings.
Authentication
Send an API key as a bearer token. The key must carry the hosting.cdn.manage permission; a key without it is refused with 403, not 404.
This endpoint takes no organisation id. Your key already identifies the organisation it belongs to, and the response is scoped to it.
Try it
Replace anything in angle brackets with your own values, and the key placeholder with a key from your dashboard.

-d '{ }'Signed in? The API console in your dashboard fills in your real organisation id and your own key, and runs the request against the live API so you can see the actual response. Open this endpoint in the API console
Details
A **merge**: only the fields present are changed. A full-object write would turn a customer's AI-crawler policy off every time they changed their security level. The body carries settings and nothing else — `additionalProperties: false`, for the reason `PUT /v1/sites/{siteId}/cdn/settings` gives: these are pooled CDN accounts and a Cloudflare zone resolves by name alone, so a body key named `domain` or `zone_id` must be refused rather than discarded. The result is read back from the provider rather than echoed, because the provider silently ignores a bot control a zone's plan does not include — "we asked" and "it changed" are different facts. Requires `hosting.cdn.manage`. **Bot management is a sold entitlement (`protection_tier`).** Turning `bot_fight_mode` on, or setting `ai_bots_protection`/`crawler_protection` to `block` or `managed_challenge`, needs a plan that includes it and otherwise answers a plan refusal naming the tier held and the tier needed. Three things are deliberately NOT gated. Turning any control **off** is free on every plan — a customer whose plan changed must always be able to reach the floor rather than be stranded with a setting they cannot undo. `allow` is an explicit relaxation, not protection, so it is free too. And `security_level: under_attack` is free on every plan, for ever: it is the emergency DDoS response, and refusing it to a customer under active attack because of their plan is not a product decision this platform will make.

Response
| Name | Type | Required | What it is |
|---|---|---|---|
site_id | Uuid | Yes | UUIDv7 identifier — sortable by creation time (docs/02 §8). |
supported | boolean | Yes | Whether the CDN serving this site can express these settings at all. `false` for a provider with no equivalent vocabulary; the other fields then carry defaults and a client shou… |
protection_tier | string | Yes | The protection level this organisation's plan sells (`protection_tier`). Absent from a plan means the floor — every site with a CDN already has the provider's baseline protectio… |
bot_management_included | boolean | Yes | Whether that tier reaches bot management — enabling `bot_fight_mode`, or setting `ai_bots_protection`/`crawler_protection` to `block` or `managed_challenge`. Derived server-side… |
security_level | CdnSecurityLevel | Yes | The provider's own security-level vocabulary, passed through. **Not ordered the way it reads** — `essentially_off` sits between `off` and `low` — so nothing may treat it as a sc… |
bot_fight_mode | boolean | Yes | Challenge traffic the provider classifies as automated. Read from the provider's bot-management resource, not from a zone setting — the zone setting of that name does not exist. |
ai_bots_protection | CdnAiBotMode | Yes | How the edge treats AI crawlers. `disabled` leaves them alone. This is the control on the screen most able to cost a site traffic, in either direction: blocking AI answer engine… |

opportunistic_encryption | boolean | Yes | Advertise HTTP/2 over TLS to clients that arrive over plain HTTP. |
min_tls_version | CdnMinTlsVersion | Yes | The oldest TLS version the edge will negotiate. A string — `1.10` is not a version. |
