Summarize

Get a concise, AI-generated summary of a page's main content, formatted as Markdown. Useful for previews, digests, newsletters and triaging long articles.

This is an AI operation: it sends the page to a language model, so it costs 17 credits per call. See Credits.

Summarize a page

Body parameters

Name
url
Type
string
Required
Required
Description
The absolute URL of the page to process. Rendered with headless Chrome, so JavaScript runs and redirects are followed. It must not include a username or password (https://user:pass@example.com).
Name
page_options
Type
object
Description
Wait for the page, and remove ads, cookie banners or your own elements from it before it is read — gone from this result, not merely hidden. See Page options.
Name
residential
Type
boolean
Description
Fetch the page from a residential exit — an address on a home broadband line rather than one in a datacentre. Reach for it when a site serves you less than it serves a browser, or nothing at all. Defaults to false. Adds 25 credits per page fetch on top of what the operation costs, and its results are kept separate from the ordinary ones.
Name
report_to
Type
string
Description
Webhook URL — an http or https address URLpipe POSTs the result to when it's ready. Optional: without it we deliver to your project's default endpoint if it has one, and otherwise send no webhook at all — the result still waits for you at GET /result/:token. A value we cannot deliver to returns 422. Ignored on a sync=true request. Deliveries can be signed so your endpoint can verify they came from us.
Name
sync
Type
boolean
Description
Process the request synchronously, returning the result inline in the response. Defaults to false (async: return a token now, and either receive the result at a webhook or fetch it with GET /result/:token). See Async & sync modes for the full contract.
Name
max_age
Type
string | integer
Description
How fresh a cached result must be to be accepted. Either an integer number of seconds (3600) or a duration string of the form "<number> <unit>" — units s/min/h/d/w (e.g. "2 hours", "3 days", "30m"). Defaults to 7 days, clamped to a max of 30 days; 0 always bypasses the cache. See Caching for all accepted units.
Name
labels
Type
object
Description
Your own keys to find and account for this request by — a client, a project, a campaign: {"client": "acme"}. Returned with the result, in the webhook and in the X-Labels header, and your dashboard filters history and totals credits by them. Up to 16 keys; string values. See Labels.

Response

Content type text/plain — a Markdown summary, typically three to five short paragraphs.

POST/summarize

curl -X POST https://urlpipe.dev/summarize \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"url": "https://example.com"}'

const res = await fetch("https://urlpipe.dev/summarize", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_API_KEY",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({ url: "https://example.com" }),
})

$ch = curl_init("https://urlpipe.dev/summarize");
curl_setopt_array($ch, [
    CURLOPT_POST => true,
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_HTTPHEADER => [
        "Authorization: Bearer YOUR_API_KEY",
        "Content-Type: application/json",
    ],
    CURLOPT_POSTFIELDS => json_encode(["url" => "https://example.com"]),
]);

$response = curl_exec($ch);

Response

The page introduces the Example Domain, a reserved domain name set
aside for use in documentation and illustrative examples.

It explains that the domain can be referenced in articles and other
literature without needing prior permission or coordination, and links
to further information maintained by IANA.

AI endpoints accept up to 10 MB of HTML. For the full content rather than a summary, use /markdown.

Responses

Whatever the status, the response carries metadata headers: the result token, whether it was served from cache and how old that result is, how long we took, what it cost in credits, and the allowance you have left.

Status

When

Body

200 OK

The request succeeded.

Sync: the result, in this endpoint's format (see Response above). Async: a job token and the request's labels — { "token": "…", "status": "accepted", "labels": {} }.

422 Unprocessable Entity

The analysis failed, or a parameter was invalid (a bad max_age, a screenshot_options value out of range, labels that break the rules, or a report_to we will not deliver to).

{ "error": "<message>" }

429 Too Many Requests

Three causes, told apart by the error field: concurrency_limit (too many of your requests already running), rate_limited (sending too fast), or quota_exceeded (Free plan only — out of credits with no card on file to bill the extra to, and checked only on a cache miss; a paid plan keeps serving at the overage rate and is never refused for credits).

All three carry "error" and "message". Extra fields: concurrency_limit → "limit", "running" · rate_limited → "retry_after" · quota_exceeded → "limit", "used", "needed", "resets_at".

504 Gateway Timeout

Sync only: the analysis didn't finish within 60s. It keeps running — fetch it via GET /result/:token.

{ "error": "processing_timeout", "token": "…" }

401 Unauthorized

Missing or invalid API key.

{ "error": "invalid_api_key", "message": "…" }
