Every Blujay phone number is on one of three plans, and a workspace can hold numbers on different plans. A new workspace starts with a Free Plan number. The plan decides who the number can message and which features it can use. The API is the same on every plan; the difference is which requests succeed. The sending rules apply on every plan.

Free Plan

A new workspace starts on the Free Plan with a phone number that other Free Plan workspaces share.
  • A person must text your Free Plan number first, and you verify them in Blujay under Contacts. Then you can message them through the API. Sending to anyone else returns 403 CONTACT_NOT_VERIFIED.
  • You can have up to 10 verified contacts.
  • Group chats and group operations return 400 FEATURE_NOT_ENABLED.
  • GET /v1/phone-numbers shows the number with access_type: "shared" and leaves out limits, queue and health_status. Use send_status to see whether it can send.
  • Typing indicators, read receipts and the sending rules work the same as on other plans.
The Free Plan is for trying the API with your own phone. See the Quickstart.

Dedicated

A Dedicated number is yours alone, with full functionality: start conversations with anyone who hasn’t opted out, group chats, and every iMessage feature the API offers.
  • GET /v1/phone-numbers reports its live limits, queue and health_status.
  • It can message up to 50 new contacts a day once established. A new or recently reassigned number may start lower and reaches the full limit over about its first month. See Phone numbers and limits.
  • When a contact texts exactly STOP, Blujay opts them out automatically. See Opt-outs.

AI Agent

An AI Agent number is your own number set up to reply, not to reach out. It is built for assistants that answer people who text in.
  • A person must text the number first. A send to anyone else, and any group chat request, returns 403 CONTACT_MUST_TEXT_FIRST.
  • Once someone has texted the number, you can message them like any other contact, with media, replies, effects, edit and unsend.
  • If a contact adds the number to a group chat, messages from that group still arrive, but the number can’t send into it: group sends return the same 403.
  • GET /v1/phone-numbers reports limits, queue and health_status as for a Dedicated number.

Tell plans apart in the API

  • access_type is shared on the Free Plan and dedicated on Dedicated and AI Agent numbers.
  • outbound_policy.inbound_first is true on Free Plan and AI Agent numbers, the ones that can only message people who texted first. Skip them when you start conversations. It’s false on Dedicated numbers.
