Reading a single page and extracting what is on it

Sometimes the task is one page whose address you know, read once: no sign-in, nothing changed. It is the lightest thing the browser core does.

The structure

/opt/dinoer/venv/bin/python3 /opt/dinoer/shot.py \
  --url https://example.com --a11y --guide-version 1.6

{"succes": true, "http_status": 200,
 "a11y_tree": "- heading \"Example Domain\" [level=1]\n- paragraph: This domain is for use in documentation examples…",
 "boussole": {"titre_page": "Example Domain", "dernier_code_http": 200}}

--a11y returns the accessibility tree as text: roles, links, headings.

The cleaned text

{"type": "extraire_texte"}

{"extraction_texte": {"titre": "Example Domain",
 "texte": "Example Domain\nExample Domain\nThis domain is for use in documentation examples without needing permission. Avoid use in operations.\nLearn more",
 "url": "https://example.com/", "date_capture": "2026-08-14T13:23:35+00:00"}}

Same session as the output above. The tree gives the structure; extraire_texte gives the text of the page without markup or noise tags, when what you need is what the page says.

Precise values with evaluer

{"type": "evaluer",
 "script": "document.querySelector('.price')?.textContent.trim()"}

evaluer returns a value your code can compare: a price across several sources, an entry in a list, a field of a page built in JavaScript. On such a page, wait for the network to calm down (attendre_reseau_calme) before reading; a script that runs before the page’s own scripts reads nothing.

When this is not the right task

A single page whose address you know is this case. A subject you have not narrowed down, across sources you do not know yet, is a campaign: the research campaign →.

And some commercial platforms refuse an agent whatever you ask of it. What the web refuses →

In short

• No image in any mode: --a11y and extraire_texte are all that reading a page returns.
• evaluer for precise values your code can compare.
• Wait for the page to settle before reading anything built by JavaScript.
• One known page: read it directly. An open question over unknown sources: a campaign.
