ChatGPT

POST /api/v1/search/ai/chatgpt puts one prompt to chatgpt.com  the way a guest in a browser would and returns the reply: its text, the same text as Markdown and as the page’s HTML, the pages it cites, and the stream the page received while the reply was arriving. You send no code and no account: the task is dat.ai’s own script, run as a Browsing API task with the same key, the same billing and the same task_id in GET /api/v1/browsing/status.

An address the engine will not serve (“Unable to load site”), a challenge page, a page with no composer, a reply that never came: none of these is an answer. Such an attempt counts as a failure and the server tries again from elsewhere: first within fanout (the first reply wins), then with the next round of attempts from browsers and IP addresses not yet tried. You pay only for the task that returned the reply.

The engine decides for itself whether to search the web for a prompt; a prompt that asks for sources gets them. The request and the reply are the ones every engine shares, see AI Search; what is ChatGPT’s own is below.

What is ChatGPT’s own

FieldOn this engine
final_urlThe guest conversation, https://chatgpt.com/uc/<id>
sourcesOne per address, in order of first mention; attribution is the name the engine shows for the page, which is not always its domain
citationsThe citation pills in the text; supporting marks the pages the engine lists as additional to a pill (“+1”)
raw_streamNot a Server-Sent Events body: the page fetches the reply as streamed HTML patches (text/vnd.openai.web-mobile-partial+html), handed back as they came
status: partialThe reply had not finished streaming in timeout_sec; what was on the page is returned

Refused on the node, so that the request moves on to another browser: an address the engine will not serve (“Unable to load site”, roughly one node in four or five), a challenge page, a page with no composer, a reply that had not begun after 30 seconds.

Example

curl -sS -X POST "https://llm.dat.ai/api/v1/search/ai/chatgpt" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{

    "locale": "en-GB",
    "raw_stream": false
  }'

Response (200), as the engine answered it (the sources and citations cut to two of four; raw_stream is absent because the request turned it off):

Errors. The body is always { "error": "..." }; these are the answers as the server gives them:

// 400 — no prompt, a value out of range, a field the endpoint does not know
{ "error": "prompt is required" }
{ "error": "attempts must be between 1 and 5" }

{ "error": "Insufficient balance: the browser_seconds quota is used up and there is no USD balance to cover overage; top up in the dashboard (https://dash.dat.ai) or check GET /api/v1/account/balance", "code": "insufficient_balance", "exhausted": "browser_seconds" }
 
// 404 — an engine that does not exist
{ "error": "unknown answer engine" }
