How an AI agent can contact us
If you are an agent writing on behalf of a customer, here are the channels, the fields and what happens next. We accept messages from automated agents on all of them.
Channels
| Channel | Address |
|---|---|
| JSON endpoint (preferred) | POST https://www.differentgrowth.com/api/contact |
| OpenAPI docs | https://www.differentgrowth.com/openapi.json |
| Contact form | https://www.differentgrowth.com/en/contact |
| contact@differentgrowth.com | |
| +34 616 541 977 (https://wa.me/+34616541977) | |
| Request a free audit | https://www.differentgrowth.com/en/audit |
Public JSON endpoint
Send a POST to https://www.differentgrowth.com/api/contact with a JSON body and the header Content-Type: application/json. It is public. No authentication, no API key. The full spec is at https://www.differentgrowth.com/openapi.json.
Required fields:
- name: up to 100 characters.
- email: a valid address.
- message: up to 5000 characters, with three links at most.
Optional fields:
- phone, company, website and locale (es or en).
- agentName: the name of the agent or tool sending, up to 100 characters.
- onBehalfOf: the person or organisation you act for, up to 200 characters.
Any field not on this list gets the request rejected with a 422, so nothing is dropped without notice. A successful request returns 202. Requests are rate-limited and screened for spam; go over the limit and you get a 429 with a Retry-After header. Whatever you send reaches the same inbox as the contact form.
Example (made-up data):
{
"name": "Laura Martín",
"email": "laura@example.com",
"message": "I run a dental clinic in Valencia and the website brings no patients. I want to know what to fix first.",
"website": "https://www.example.com",
"locale": "en",
"agentName": "Laura's assistant",
"onBehalfOf": "Laura Martín, Example Clinic"
}Contact form
If you can't use the endpoint, go to https://www.differentgrowth.com/en/contact. Fill name, email and message and leave any other field empty. The button reads "Send message".
Email and WhatsApp
- Email: contact@differentgrowth.com
- WhatsApp: +34 616 541 977, direct link at https://wa.me/+34616541977
The form, email and WhatsApp have no fields to identify you, so say in the message itself that you are an AI agent and who you are writing for.
Free audit
Our homepage describes it as a free 20–30 or 30–60 minute call, on Zoom, Meet or WhatsApp, where we filter for fit and what to move first.
You request the audit; there is no self-service booking. The request lives at https://www.differentgrowth.com/en/audit and is a four-step form. Step one asks for full name, email and company, plus an optional phone number. The later steps ask about your business, your current online presence and the problems that concern you most. We accept only a few requests per month and pick projects based on our current capacity.
What happens next
We reply within 48 hours to messages from the endpoint, form, email or WhatsApp, including audit requests.
If we can help, we propose a next step. If we are not a fit, we say so. You speak with the people who will shape the project.
Pricing
We work with a tailored quote after the free audit.
What to include in a message
- Business type. For example, a clinic or a local business.
- City.
- Current website URL, or a note that there is no website yet.
- What your customer wants to fix, in their own words.
- Name and email of the person you represent, so the reply reaches them.
- Who you are and who you act for. On the endpoint, that goes in agentName and onBehalfOf.
