Response headers

HTTP headers returned by AgentXP on markdown responses.
When AgentXP detects an AI agent and serves a markdown response, it sets a standard set of HTTP headers. These headers communicate content type, permissions, token count, and SDK metadata to the requesting agent.

​
Headers

​
Content-Type

Type: string Always set to text/markdown; charset=utf-8 on markdown responses. Signals to the agent that the body is markdown, not HTML.

​
Content-Signal

Type: string Communicates your content permissions to agents as a comma-separated list of key=value directives. See Content-Signal values below for the full list. Default value: ai-train=no, ai-input=yes, search=yes

​
X-Markdown-Tokens

Type: number Estimated token count of the markdown response body, calculated as Math.ceil(body.length / 4). Agents can use this to budget context window usage before reading the full response.

​
X-AgentXP-Version

Type: string The version of the AgentXP SDK that served this response. Current version: 0.1.0.

​
X-AgentXP-Agent

Type: string The name of the detected agent (e.g., "ClaudeBot", "GPTBot"). Set to "unknown" when the agent was detected via the Accept: text/markdown header but no matching User-Agent pattern was found.

​
/llms.txt only

​
Cache-Control

Type: string Set on /llms.txt responses only: public, max-age=3600, s-maxage=86400. Allows CDNs to cache the manifest for up to 24 hours.

​
Example response

HTTP/2 200
content-type: text/markdown; charset=utf-8
content-signal: ai-train=no, ai-input=yes, search=yes
x-markdown-tokens: 847
x-agentxp-version: 0.1.0
x-agentxp-agent: ClaudeBot

​
Content-Signal values

The Content-Signal header communicates your content permissions using three directives. Configure these values via the permissions key in your AgentXP config.

​
ai-train

Type: yes | no Whether you permit AI providers to use this content for model training. Defaults to no.

​
ai-input

Type: yes | no Whether you permit AI agents to use this content as inference input (e.g., for RAG, summarization, or question answering). Defaults to yes. Type: yes | no Whether you permit search indexing of this content. Defaults to yes. To change the defaults, set the permissions option in withAgentXP: 
withAgentXP({
  permissions: {
    aiTrain: false,
    aiInput: true,
    search: true,
  }
})
