Was er kann

Tool-Namen und -Beschreibungen genau so, wie der Server sie am 7. Nov. 2026 gemeldet hat. Geschrieben hat sie der Entwickler, nicht wir; wir zeigen sie als reinen Text.

• place_call

  Originate an outbound phone call. Provide ``system_prompt`` (mode A — Hail's bundled fallback LLM uses this prompt) or ``llm`` (mode B — bring your own OpenAI-compatible endpoint as ``{"base_url": ..., "api_key": ..., "model": ...}``), or both, or ``agent_id`` (a saved agent from

• send_email

  Send an outbound email through your configured SES sender. ``to`` is a non-empty list of RFC-style email addresses. At least one of ``body_text`` / ``body_html`` is required (both is fine — multipart-alternative). Prefer including ``body_html``: open and click tracking only works

• upload_email_attachment

  Upload a file to attach to a future outbound email. ``content_base64`` is the file's raw bytes, base64-encoded. Returns ``{"id": ..., "filename": ..., "content_type": ..., "size_bytes": ...}`` — pass ``id`` in ``send_email``'s ``attachment_ids`` list. The id is reusable across ma

• get_call

  Fetch the current state of one call by id. Use this after ``place_call`` (or to check on any prior call) to read the call's latest ``status`` and timing fields. Returns the API's ``CallResponse`` as a dict, or ``{"error": "call not found"}`` for an unknown id.

• list_calls

  List recent calls in your organization, newest first. Cursor-paginated: pass the previous response's ``next_cursor`` to fetch the next page. ``status`` (one of queued, dialing, ringing, in_progress, completed, failed, busy, no_answer, canceled) and ``to`` (E.164) are optional ser

• send_sms

  Send an outbound SMS. ``to`` must be E.164 (e.g. ``+14155551234``). ``body`` is the message text. With no ``from_``: destinations where the sender-ID carrier delivers a dynamic alphanumeric sender ID unchanged (about 110 countries, see core/hailhq/core/sender_id_corridors.py) use

• get_sms

  Fetch the current state of one SMS by id. Use this after ``send_sms`` to check delivery status. Example: get_sms(sms_id="...")

• list_sms

  Page through recent SMS messages for your organization. ``status`` filters to one of: queued, sent, delivered, failed, undelivered, received. ``to`` filters to messages sent to a specific E.164 number. Paginate with the returned ``next_cursor``.

• get_email

  Fetch the full record of one email by id. Returns the complete row — including ``body_text`` / ``body_html`` and (for inbound mail) the ``in_reply_to`` / ``message_id`` headers and ``spam``/``virus``/``spf``/``dkim``/``dmarc`` verdicts. Use this after ``list_emails`` to read a re

• list_emails

  List emails in your organization, newest first. Cursor-paginated: pass the previous response's ``next_cursor`` to fetch the next page. Two optional server-side filters: * ``direction`` — ``outbound`` or ``inbound``. Pass ``direction="inbound"`` to read replies and other received

• get_email_raw

  Get a fetchable URL for an email's original MIME source. Returns ``{"url": " "}`` — a short-lived (~5 minute) link to the full raw RFC822 message. Fetch the URL directly to read the complete original; it needs no auth header. Raw source exists for **inbound** mail only — outbound

• get_email_attachment

  Get a fetchable URL for one inbound email attachment. ``attachment_id`` comes from an item in ``get_email``'s ``attachments`` list. Returns ``{"url": " "}`` — a short-lived (~5 minute) link to the attachment bytes, fetchable directly with no auth header. Unknown ids return ``{"er

• get_email_events

  Delivery/engagement timeline (sent→delivered→opened…) for one email. Chronological lifecycle events for a single email — use this to see exactly what happened to one message (bounced? opened? clicked?) rather than the account-wide aggregates ``get_email_stats`` returns. Returns `

• get_email_stats

  Account-level email deliverability stats (counts, rates, time series). Aggregates across your whole organization's outbound mail over a window — use this for "how's deliverability doing" rather than one message's history (``get_email_events`` covers that). ``from_`` / ``to`` are

• get_events

  Page through events from across the org or one resource. Pass ``id=" : "`` to narrow to a single resource — supported types are ``call``, ``email``, and ``sms`` (e.g. ``id="sms: "`` after ``send_sms``). When narrowed to a call, the response includes a ``call_status`` field reflec

• list_agents

  List the workspace's saved agents: the brains that answer calls and texts on its numbers, and that ``place_call`` can use via ``agent_id``. Returns ``{"items": [{"id", "name", "system_prompt", "first_message", "ai_disclosure", "ai_disclosure_line", "voice_config", "tools", "max_d

• create_agent

  Save an agent. Then call ``route_number`` so a number answers with it, or pass its id as ``agent_id`` to ``place_call``. ``system_prompt`` is what the agent follows. ``first_message`` is spoken after the AI line; omit it to let the caller speak first. ``ai_disclosure_line`` repla

• route_number

  Choose which agent answers a number's calls and texts. ``voice_agent_id`` makes the number answer calls with that agent (Hail registers it for inbound at the carrier and LiveKit); ``clear_voice=True`` stops answering calls. ``sms_agent_id`` makes the agent reply to texts; ``clear

• quote_numbers

  Compare live phone-number offers from the carriers. Read-only: it buys nothing and charges nothing. ``country_code`` is an ISO alpha-2 code such as ``"US"``. ``capabilities`` is ``["voice"]``, ``["sms"]`` or both (default). ``number_type`` is ``local``, ``mobile``, ``national`` o

• acquire_number

  Buys a real phone number. It charges the setup fee and the first month now and renews monthly. Call quote_numbers first. Pass the offer's quote_id, country_code, number_type, and confirm_total_cents = monthly_cents + setup_cents from that offer. If the quote expired or the price

• list_numbers

  List the workspace's dedicated phone numbers, newest first. ``limit`` is 1..200 (default 50). Pass the returned ``next_cursor`` as ``cursor`` for the next page. Returns ``{"items": [{"id", "e164", "country_code", "number_type", "capabilities", "provisioning_state", "voice_agent_i

• list_number_regions

  List the US state and Canadian province codes that quote_numbers accepts as ``region`` (optional, with ``city``). Returns ``{"regions": [{"country_code", "code", "name"}]}``, such as ``{"country_code": "US", "code": "AZ", "name": "Arizona"}``, or ``{"error": " "}``.

• get_number

  Fetch one dedicated number by id: its state, capabilities and which agents answer its calls and texts. ``number_id`` comes from ``list_numbers``. Returns the ``PhoneNumberResponse`` as a dict, or ``{"error": " "}``.

• release_number

  Release a phone number. DESTRUCTIVE and permanent. Calls and texts to the number stop. This month's fee and any earlier months are still billed. There is no refund. The number may not be recoverable. Ask the user before calling this. ``confirm_e164`` must equal the number's ``e16

• get_verification_requirements

  Read what the carrier needs to verify the organization before it can buy a number. Call this when quote_numbers shows an offer with ``readiness == "verification_required"``. Read-only. ``country_code`` is ISO alpha-2 (for example ``"GB"``). ``number_type`` is ``local``, ``mobile`

• submit_verification

  Send the user's personal or company details and identity documents to the carrier for verification. IRREVERSIBLE: once submitted it cannot be cancelled, and the carrier keeps the documents. ``attest_authorized``: pass true only if the person or company named in these details and

• list_verifications

  List the organization's carrier verifications, newest first. ``purpose`` is ``number`` or ``sms``; only that kind is listed. Omit to see every registration. ``purpose='sms'`` lists the registrations to text US numbers from a US number. Returns ``{"items": [{"id", "country_code",

• get_verification

  Fetch one verification and its state. Use it to poll. There is no notification, and review takes business days. Poll every few minutes to hours, not every few seconds; the state refreshes from the carrier at most once a minute. On ``approved``: call quote_numbers again. The offer

• cancel_verification

  Cancel a verification that has not been sent for review, or dismiss a rejected one (needed before submitting a new one for the same country and number type). The draft is discarded. Works in state ``awaiting_review`` or ``rejected``, and for an ``approved`` US SMS registration (`

• confirm_verification

  When a registration shows confirmation 'code', ask the person for the code the carrier texted and submit it here. ``verification_id`` comes from submit_verification or list_verifications. ``code`` is 4 to 10 characters. A wrong or expired code is an error naming ``code``; the car

• get_agent

  Fetch one saved agent by id. ``agent_id`` comes from ``list_agents`` or ``create_agent``. Returns the ``AgentResponse`` as a dict (``name``, ``system_prompt``, ``first_message``, ``ai_disclosure``, ``voice_config``, ``tools``, ``voice_enabled``, ``sms_enabled``, ``status``, ...),

• update_agent

  Change a saved agent. Safe to repeat: the same call gives the same result. Only the fields you pass change; a field left out keeps its value. ``status`` is ``"live"`` or ``"paused"``; a paused agent does not answer. ``language`` is a lowercase ISO 639-1 code. Pass ``language`` or

• delete_agent

  Delete a saved agent. DESTRUCTIVE. Ask the user before calling this. Numbers that used the agent stop answering with it: calls ring out and texts reach webhooks only. Reroute them first with ``route_number`` if that matters. ``confirm_name`` must equal the agent's ``name``. The t

• list_contacts

  List the workspace's contacts: org members (with their phone/email) plus manually saved contacts. Use ``lookup_contact`` for name searches. ``q`` optionally filters server-side (matches name/email/phone). ``limit`` caps the page (server default 100, max 500). Returns ``{"items":

• lookup_contact

  Find a contact by name, email, or phone fragment. Resolve a person to their ``phone_e164``/``email`` BEFORE calling ``place_call``, ``send_sms``, or ``send_email`` — do not guess a contact's number. Returns up to 10 matches, same item shape as ``list_contacts``. Example: lookup_c

• list_email_domains

  List the addresses this workspace can send email from. Call this BEFORE ``send_email`` when you do not already know the ``from_`` address — do not guess a domain. Returns ``{"items": [...], "next_cursor": ..., "default_from": ...}``. Each item carries ``domain``, ``kind`` (``"cus

• whoami

  Identify the human whose credentials this session runs under. Use it to sign or route mail as that person: pass their address as ``send_email(reply_to=...)`` so replies reach them rather than the sending domain, which is often an unattended ``noreply@``. Returns ``{"auth_kind", "

• create_contact

  Save a new contact for the workspace. Provide at least one of ``phone_e164`` (E.164, e.g. ``+14155551234``) or ``email`` — the API rejects (422) a contact with neither. A duplicate phone or email on an existing contact returns 409. Example: create_contact(name="Maya Chen", phone_
