Bird introduces self-serve signup for AI agents

Bird launches a headless signup path for agents that don't already have a Bird account. Three commands take an agent from nothing to a stored, working credential: bird auth signup creates the account and emails a six-digit code, bird auth verify-email confirms it and returns a one-time onboarding ticket, and bird auth create-org consumes that ticket to create the first organization and workspace. No browser and no dashboard involved at any step. The same flow is exposed as the signup, verify_email, and create_org tools on the MCP server. See Self-serve signup.

Also in this release:

• The dashboard's navigation is redesigned around a left sidebar: channels are grouped under Products (Voice, Push, Lookup, and Realtime now sit in a coming-soon row), shared records live under Resources (Contacts, Numbers, Verification), and API Keys, Webhooks, and Logs are pinned at the bottom and stay visible no matter which channel you're in. See the dashboard tour.
• WhatsApp message endpoints (get, list, list message events, send) now return last_error.meta_error_code, the raw error code from the WhatsApp Cloud API, for lower-level debugging of failed sends.
• Corrected docs: enabling email receiving on a domain is dashboard-only, through the Receiving toggle on the domain's detail page. The previously documented PATCH /v1/email/domains/{domain_id} call for this doesn't do that. Separately, the 422 error returned for preview email fields (references, attachment path, contact_id, topic_id) used ahead of general availability is UnsupportedEmailFeature, not unsupported_feature as previously documented.
