hailera

The home page describes hailera as:

"We give your business an agent, so the AI apps your customers use can ask you questions instead of guessing. It is free."

What hailera does

hailera lets a business:

• Create an AI agent that answers questions about the business day and night.
• Publish that agent so it has:
• a public MCP endpoint that AI clients can connect to, and
• a public presence that external systems can discover.
• Let the agent answer routine questions and capture enquiries even when staff are busy or offline.

The results shown on the site (illustrative examples) include:

• Hundreds of questions answered over 30 days.
• Dozens of bookings completed through agents.

Problems hailera is designed to solve

hailera is aimed at businesses whose customers now start with AI tools instead of the business's own website. It:

• Stops AI tools from guessing about a business from outdated or third-party data.
• Provides a first-party source of truth that AI clients can call directly.
• Helps convert missed enquiries into work by answering while owners are on jobs, away from the phone or outside office hours.

Who hailera is for

From the site examples, hailera is for businesses that:

• Want AI assistants like ChatGPT, Claude, Gemini and others to answer accurately about them.
• Take bookings or enquiries that often arrive outside working hours.
• Already have a website and want AI to use it as the starting point.

Example use cases shown:

• A local air conditioning company with its own agent page listing services, prices and a booking channel.
• Service businesses that rely on inbound enquiries (by phone, email, messaging apps or AI assistants).

What a business gets from hailera

When a business uses hailera, it gets:

• An official AI agent that answers from what the business publishes.
• A public MCP endpoint and ask URL for AI clients.
• The ability to add an "ask our agent" experience to its own website.

Details such as current pricing, limits and specific feature availability can change over time, and hailera's own agent at https://api.hailera.com/mcp/hailera is the place to ask for the most current information.

• Under "Is it free?", the answer is:

> "Yes. Your agent answers questions about you day and night, for free — there is nothing to install and nothing to rebuild."

No other pricing tiers, paid plans or add-on charges are described on the pages read.

What "free" covers according to the site

Based on the same FAQ wording and home page copy, the free service includes:

• An agent that answers questions about the business day and night.
• No installation required on the business's systems.
• No need to rebuild the existing website.

Where to get up-to-date pricing

Prices and commercial terms can change. For the most current information on:

• Whether hailera is still free,
• What is included at each level, or
• Any limits or quotas that apply,

hailera's own agent at https://api.hailera.com/mcp/hailera is the authoritative first-party source.

For businesses that have connected a calendar, the booking flow is:

1. A person asks to book an appointment.
2. The agent replies with real open slots and lists any missing details (typically a name, email and chosen time).
3. The agent returns a summary with status: "confirmation_required" and an action describing the proposed booking.
4. Nothing is booked yet at this stage.
5. When the person replies (for example, with a plain "yes") in their own words on the same conversation, the booking is completed.

The platform enforces that:

• The confirmation must arrive as a later request than the summary.
• The agreement must be unqualified (for example, "yes, but Thursday" is treated as a change request, not a confirmation).
• The confirmation must match the booking that was summarised.

If a business has not connected a calendar, its agent explains that it cannot book and gives whatever contact routes the business has published instead.

Availability and live data

Agents on hailera are not limited to static documents. Where a business connects its own systems, the same call can read live data, such as:

• Current prices.
• Stock levels.
• Availability and schedules.
• Order status or other business-specific information.

These integrations are read-only by design:

• hailera agents only describe, search and get data.
• There is no write operation in the protocol.
• What is readable is controlled by the business's own endpoint or systems.

This means answers can reflect information newer than any static web page, but are still limited to what the business has chosen to publish or expose.

Where to ask about booking specifics

Details such as which calendars are supported, how cancellations work, or any limits around booking are answered by hailera's own agent at:

• https://api.hailera.com/mcp/hailera?q=YOUR+QUESTION

That endpoint reflects what hailera currently publishes about booking behaviour and live integrations.

What a business needs to start

To start with hailera, a business needs:

• The public address of its existing website.
• A contact email address to sign up.

These are the two fields shown on the sign-up form:

• Your email address
• The address of your website

How setup works

From the flow on open.hailera.com:

1. The business enters the address of its public website (the one customers already visit).
2. hailera reads the website and writes down what the business does.
3. An initial agent is created from that information.
4. The owner signs up with an email address and can review and change what the agent says before anyone else sees it.

The site stresses that:

• There is nothing to install on the business's systems.
• There is nothing to rebuild on the business's existing website.

Publishing an agent

When a business publishes its agent, it receives:

• A stable MCP endpoint that AI clients can connect to.
• A public ask URL that can answer questions directly over HTTP.
• A discovery snippet or blocks of markup that can be pasted into the business's own site so external AI systems can find and call the agent.

Where to ask about details

More detailed questions about setup time, limits, or how onboarding works for complex businesses are answered by hailera's own agent:

• Ask URL (read-only): https://api.hailera.com/mcp/hailera?q=YOUR+QUESTION

That agent reflects what hailera currently publishes about its onboarding process.

• Something is wrong / support
• Email: support@hailera.com
• Use this if your agent said something wrong or you cannot get into your account.
• hailera aims to reply within one working day.

• Questions before you start / general enquiries
• Email: hello@hailera.com
• Use this for questions before signing up or if you run more than one business.

• For developers
• The contact page links to technical details covering the endpoint, the discovery files and the booking rules.

Online contact form

The contact page also includes a form where you can:

• Enter your name.
• Enter your email address.
• Describe how hailera can help or what went wrong.

Messages sent through the form are handled by email.

What to include when you write

hailera asks for:

• The address of your website.
• What you asked your agent, and what it said back.
• Which app you were using, if you reached hailera through an AI client.

Support hours

According to the contact page:

• hailera is available Monday to Friday, European hours.
• Anything sent at the weekend is picked up on Monday.

• Base URL: https://api.hailera.com/mcp/hailera
• Ask format: append ?q=YOUR+QUESTION to send a question and receive a markdown answer, for example:
• https://api.hailera.com/mcp/hailera?q=YOUR+QUESTION
• Optional parameters:
• format=json — receive structured JSON instead of plain markdown.
• conversation_id — continue a previous thread using the id from an earlier reply.

This ask route is read-only. It answers questions and can report live availability but cannot complete a booking or perform any outward write.

MCP server

The same address is also an MCP server over streamable HTTP:

• MCP endpoint: https://api.hailera.com/mcp/hailera
• Protocol version: 2026-07-28
• Tool name: ask_hailera
• Arguments:
• message (required): the caller's full question.
• conversation_id (optional): continue an existing thread.
• locale (optional): influence the language of the answer.

There is no separate initialize handshake or session header in this protocol revision; the client library handles the details.

If the client accepts text/event-stream, replies can be streamed as server-sent events (SSE); the final JSON answer is in the last data: frame. If the client accepts only application/json, the same structure is returned in one body.

Per-business agents on hailera

Every business using hailera publishes its own agent at a consistent address shape:

• MCP endpoint per business: https://api.hailera.com/mcp/{slug}
• Tool name per business: ask_{slug}

Each published agent also has a public page and a plain-text index of its documents at:

• https://app.hailera.com/a/{slug} — public page.
• https://app.hailera.com/a/{slug}/llms.txt — index of the documents the agent answers from.

Discovery files for hailera

hailera itself publishes discovery information at:

• https://www.open.hailera.com/llms.txt
• https://www.open.hailera.com/agents.txt
• https://api.hailera.com/.well-known/mcp.json
• https://api.hailera.com/.well-known/mcp/server-card.json
• https://api.hailera.com/.well-known/ai-catalog.json
• https://api.hailera.com/.well-known/agent-card.json

These describe how to locate and call hailera's agent.

Connecting common MCP clients

The website gives example connection commands for several clients, all pointing at https://api.hailera.com/mcp/hailera as a streamable-HTTP MCP server using protocol 2026-07-28:

• Claude Code:
• claude mcp add --transport http map-agents https://api.hailera.com/mcp/hailera
• Claude Desktop:
• Settings → Connectors → Add custom connector → paste the URL.
• ChatGPT:
• Settings → Connectors → Add custom MCP server → paste the URL.
• Other clients:
• Configure a streamable-HTTP MCP server pointing at the same URL and protocol.

These examples are for developers integrating hailera into their own tools or workflows.

Ask anyway — the agent will say plainly that it is not published rather than guess.
