GPT-6 Astra computer use, or a direct API call?
GPT-6 Astra computer use can read a number off a web page; a structured Actionway call returns the same number as JSON with a receipt — a market quote is one $0.01 per run call. Use the browser when a page has no API, and the priced call when the fact has one.

Live market data. One service in the catalog answers this directly; two neighbours are listed so you can see what else the same family covers:
あなたが選択: Market Quote
- Calls the quote service once — a synchronous call, JSON back in the same turn
- Formats the four fields itself; no page was opened, nothing was scrolled or screenshotted
- Returns the answer with the raw response available to keep

That is the API path, from a real session: one call, four fields, one line on the bill. The computer-use path to the same fact — open a browser, search the ticker, wait for the page, read the number, close the tab — was not timed or costed for this article, so no comparison figure appears here. What follows is about the shape of each route, which you can judge without a stopwatch.
What happened in between
OpenAI released GPT-6 Astra on September 3, 2026 with computer use as a headline capability, and TechCrunch's coverage frames it as the model's main step forward. Since Codex CLI 0.153.4 it is the bundled default, so the choice above is one every Codex session can now make.
With the Actionway Skill installed, the agent checked its local capability index before answering, so the first reply already carried the plan: which service, and what it costs per call. It lists options neutrally — no default, no recommendation. Naming the one you want is the approval; the call runs at the shown price, Actionway checks the wallet on its side, and only calls the platform flags for extra confirmation pause for another question. Data calls are synchronous, so there is no job to wait on. If the wallet cannot cover the call, the agent stops before anything is charged and gives you a top-up link with the amount prefilled.
Pick a route, pay per call
Computer use is the right tool when there is no API: a form that only exists in a browser, a dashboard behind a login, a page whose layout is the information. It is general, and it costs whatever the browsing session costs in model time. Its weak points are the ones you would expect from reading a screen — a number is what the page rendered, a layout change is a silent failure mode, and the evidence of what was read is a screenshot.
A structured call is the right tool when the fact has a service behind it. Stock and company data covers the quote above ($0.01 per run), a name-to-symbol lookup ($0.01 per run), and standardized statements ($0.01 per run); weather alerts are free. The response is JSON with fields, not pixels, so the agent computes with it instead of transcribing it, and the receipt names the call, the price, and the time. The long tail beyond them is reached with the free actionway tools search; the API catalog lists what is there. A practical rule: let Astra drive the browser for what only a browser can show, and give it the structured call whenever one exists — the earnings briefing use case is built entirely from the second kind.
A short checklist before each task
Is there a service for this fact?
Ask the agent, or run the free catalog search. Quotes, statements, weather alerts, transcripts, downloads, and image or video generation all have one; a specific dashboard behind your own login does not.
Does the answer need to be computed with?
JSON can be added, compared, charted, and diffed. A number read off a screenshot has to be transcribed first, and a transcription error looks exactly like a real number.
Will you need to show where it came from?
A structured call leaves a receipt with the service, the price, and the time, and the raw response can be saved beside the deliverable. A browsing session leaves screenshots.
Is the page the point?
When the layout is the information — a form, a chart with no data export, a page that changes by login — computer use is the only route, and Astra is built for it.
Most tasks mix the two. A market brief might browse a company's investor page for the date of the next call and fetch the numbers through priced calls; the Skill does not take the browser away, it adds the second column to the same session and keeps the paid part itemized on the wallet statement.
Set it up once
npm install --global @actionway/cli@latest
actionway init
mkdir -p "$HOME/.codex/skills"
cp -R "$HOME/.actionway/skill/actionway" "$HOME/.codex/skills/actionway"You need Node.js 20 or newer and an Actionway account; after sign-in the agent reports your wallet balance and, if it is empty, links you straight to top-up. Prefer no local CLI? codex plugin marketplace add PawLogic/actionway-plugins then codex plugin add actionway@pawlogic loads the same catalog over Remote MCP. The get started page lists every route per client, and the the weather-alert watch guide follows the same quote into a multi-step brief.
よくある質問
Should GPT-6 Astra use computer use or an API to get data?Use computer use when the information only exists on a page with no service behind it. Use a structured call when one exists: it returns JSON, fails loudly instead of silently misreading, and leaves a receipt — the NVDA quote in this guide is one $0.01 per run call.
Is a priced API call cheaper than letting Astra browse?This guide did not time or cost the browser path, so it makes no claim about it. What it shows is the structured path: one call, one catalog price, one JSON record.
Can the two be combined?Yes. A long Astra task can browse where it must and call structured services where they exist; the Actionway Skill only adds the second option to the same Codex session.
