Set include.html to true and the task returns a link to the screen the engine showed for the answer, saved as a self-contained HTML page you can put in a report.

Request

Supported engines

The other engines reject the flag with 422 EVIDENCE_UNSUPPORTED. GET /v1/capabilities marks the supported engines with evidence: true. CHATGPT rejects it with the same error when the task has a location, asks for CN or HK, or continues a conversation with continueFrom: ChatGPT draws its page only for a new conversation answered without a device location.

Response

The task’s response gains an html object. For example:

Access and retention

  • The URL needs no API key, so it works in a link or a report. Anyone with the URL can open it until expiresAt.
  • After expiresAt the URL answers 404 and the page is deleted. Download what you need to keep.
  • One IP address can download up to 600 pages a minute; above that it gets 429.

Credits

On CHATGPT, PERPLEXITY and META_AI the page costs 0.25 credits on top of the engine’s price. They are held at submit and charged only when html.status is ok. On GEMINI, GOOGLE and AIMODE the page costs nothing extra.

When the page fails

The task still completes with its answer, and html comes back as { "status": "failed", "error": "EVIDENCE_FAILED" }, when:
  • the engine’s screen could not be collected, or did not match the answer;
  • the page could not be stored;
  • on GEMINI, the task has a location or asks for CN, DE, GB or IR. These always fail.
Resubmit the task to try again.
