How do I let my iMessage agent actually book, order and message for my users?

By , Founder of AgentWeb · As of Oct 20, 2026

Short answer. Connect your agent to AgentWeb. People text an iMessage agent tasks, not questions: "book us a table for Friday", "order my usual", "message Sam on LinkedIn". AgentWeb is the execution layer that turns those texts into finished tasks: typed web actions on 1,462 real sites (as of Oct 20, 2026), run on each user's own accounts through a hosted login, at $0.05 per completed action with failed actions refunded.

Why iMessage agents need an execution layer

A chat agent is only as useful as what it can finish. Answering "which sushi place is open?" is easy. Placing the order is the hard part, because it happens on Uber Eats, in the user's account, with their address and saved card. AgentWeb gives your agent named actions for exactly that step, like add_item_to_cart, view_checkout and place_order on Uber Eats, or book_reservation on SevenRooms.

Set it up

  1. Create an AgentWeb account and get an aw_ API key. Your agent can do this itself with agentweb_start_claim_link_signup.
  2. From your agent's backend, call AgentWeb over MCP (https://mcp.agentweb.us/mcp) or REST (POST https://mcp.agentweb.us/api/execute).
  3. When a task needs a user's account, start a hosted login with agentweb_start_connection and text the user the link. Confirm it with agentweb_poll_connection.
  4. Before anything paid or public, text the user a summary (the total, the time, the exact message) and wait for a yes.
  5. Call the action and reply with the result.

If you build on Photon's Spectrum SDK, see the Photon + AgentWeb starter.

What your agent can do from a text

  • "Book a table for 4 on Friday": SevenRooms book_reservation or DesignMyNight book_table.
  • "Order dinner": Uber Eats, from cart to place_order.
  • "Message Sam on LinkedIn": send_message, start_conversation or send_inmail.
  • "Post this on X": create_post or reply_post.

Frequently asked questions

Does the user have to give my agent their passwords?

No. Each user signs in once through AgentWeb's hosted login. Your agent never sees the password.

How does my agent know a site is supported?

Call list_actions for the domain before promising anything. The full list is at /sites/all.

What does it cost?

$0.05 per completed action, from prepaid blocks of $25, $50 or $100 that never expire. Failed actions are refunded.
