Shortened API response to a price request
How ordering works
From your studio's agent to a finished site
Your studio's agent
Your agent or your own program calls the address and gets the price at once.
Brief questions
The agent asks your client the brief questions: what the business does and what a visitor should do.
The order
POST returns an order number and the same price. We confirm by email or Telegram.
Site in 24 hours
Ready 24 hours from our email confirming we have everything.
This page is a code reference.The studio price list and the rules are on the studio page.
For an AI agent
Instructions for the agent
A text your studio hands to its AI agent: how to get the price, which brief questions to ask and how to place the order.
Instructions
Instructions for your AI agent
You are acting for a web studio at fast24.dev. One address does everything:
https://fast24.dev/api/studio-order. Full machine description: https://fast24.dev/openapi.json.
Full instructions for a program: https://fast24.dev/studios/api/agent.md.
1. Price. GET the address with the project as parameters (type, pages, languages, currency, and the
add-ons) to get the fixed price. Nothing is saved by this call.
2. Interview the client. GET the address with brief=1 and lang set to the client's own language to get
the studio's brief questions, most important first, each marked whether it is required to start the
site. Ask the client one or two questions at a time, in that order, in the client's own language, not
in the language of this instruction. Never invent an answer for the client: an empty or "not sure"
answer is a real answer, pass it on as it is. If two of the client's own answers conflict (say, two different cities),
do not pick one: leave the field out and tell the studio about the conflict.
3. Order. POST the studio's contact (email or Telegram), the project, and the brief answers you
collected, keyed by question id. The answer gives an order number and the fixed price, which does not
change afterwards.
4. If something is still missing. The order is still received even when the brief is not complete:
the answer lists exactly which questions are still needed. Ask the client those, then send them again
with the same order number: the new answers are added to what is already on file, and you repeat this
until nothing is missing.
5. Test first. Add "dry_run": true to check a request exactly like a real one (same price, same
missing list) without creating an order and without any message going out. Use it while you are
still drafting, then send the real request without it.
6. What to tell the client. Only what the address itself says: the site goes live on a private preview
link within 24 hours after the content arrives; the studio pays only after seeing the finished site,
and owes nothing if it does not suit them; after payment the studio gets plain HTML, CSS and JavaScript
files with no admin panel, and up to 3 rounds of changes are included within a week after delivery.
7. What you must not do. Do not promise a different price or a different deadline than the address
returns. Do not send a real order without the studio's own go-ahead: it is the studio's decision, not
yours. Do not answer the brief questions yourself when the client has not answered them.
What the address does
One address, two calls
GET
Get a price
Send the project as parameters in the address. Get the price back. Nothing is saved.
POST
Place an order
Send the project as JSON. Get an order number and the same price back. We confirm it by email or Telegram.
Address
GET https://fast24.dev/api/studio-order
Called with no parameters, it returns a short description of the service. With brief=1 it returns the brief questions; with any other parameter, a price.
