bullpen_aboutWhat Bullpen does, what it costs, and how to get a workspace: free with $10 of credits (no card) when your person signs in, or by paying over MPP. Call this first if you have no key. (No API key needed.)
bullpen_signupStart creating a Bullpen workspace for your principal by paying with the Machine Payments Protocol (MPP, Stripe). Returns the 402 payment challenge and the exact URL to retry with your MPP client (e.g. `npx @stripe/link-cli mpp pay <url>`). The paid retry returns an api_key; pas…
whoamiThe workspace, member and role this API key acts as.
credits_statusPrepaid credit balance and recent usage. Spending tools return a 402 error at zero.
top_up_creditsStart an MPP credit top-up ($5–$500). Returns the 402 challenge and the URL to pay and retry with your MPP client, sending your key as X-Bullpen-Key.
ask_hermanTalk to Herman, the manager agent who runs the whole bullpen in plain language: status, finding companies, running campaigns, sending the crew to call. Anything that reaches the outside world comes back as a pending action with an id — nothing goes out until confirm_herman_actio…
confirm_herman_actionRun or drop a pending action Herman proposed (a call, text or Salesforce update). Only confirm what your principal actually wants.
ask_brainAnswer a question from the workspace's own knowledge (calls, notes, docs), with sources, limited by the key's role.
find_companiesSearch for companies to sell to (e.g. 'HVAC companies in Salt Lake City'). Returns names, main phone lines and websites.
research_companyWho to ask for at a company returned by find_companies.
get_a_humanA crew member dials the number, works the phone menu, hold and AI receptionist until a real person answers, then connects the key's owner into the live call. Spends credits ($0.30 per crew minute; no extra charge when a person is reached). Company lines only unless the callee ga…
knockReach a human at a company's main line and leave a short hello pointing to your principal. Business hours, once a week per company. Spends credits.
send_textText from the workspace's line. Opt-outs are honored. Spends credits.
send_emailEmail from the workspace's agent inbox.
list_callsRecent calls, newest first: id, call SID, when, number, crew member, whether it was handed to your person, outcome, summary, and whether a transcript and recording exist. Reps see their own calls; managers and admins see all.
get_call_transcriptOne call in full: the transcript as text and as timed lines with speakers (crew, the person reached, and your person after a handoff), the summary, outcome, and a signed recording link (MP3, valid one hour). Pass an id or call SID from list_calls.
delete_callDelete the transcript, summary and recording of one call, for good (a deletion request from the person called, or your team's retention policy). The call row, its outcome and its cost remain. Reps can delete their own calls; managers and admins any.
floor_stateLive and recent crew calls.
create_campaignStart a calling campaign. Add contacts with import_campaign_contacts, then work_campaign.
import_campaign_contactsAdd contacts to a campaign from CSV text (header row: company, phone, name, title, email).
work_campaignSend the crew to work a campaign's contacts now. Spends credits.
onboarding_statusChecklist of what this workspace still needs before every feature works (Herman, compliance agreement, phone number, crew, your mobile, credits, Salesforce, Google, texting, team), in the order to do them, with the tool or link for each. Start here after signing up.
open_pageA link your person can open: floor (the live floor: who's on a call right now, and recent calls); human_line (Human line: your mobile and live bridge calls); herman (the app home, with Herman in the corner); campaigns (campaigns); companies (companies found and researched); inte…
turn_on_hermanSwitch Herman on for this member so ask_herman works.
get_outbound_agreementThe full Outbound Compliance Agreement and its version. Show it to your person before accept_outbound_agreement; calls and texts stay locked until it's accepted.
accept_outbound_agreementAccept the agreement on your person's behalf ONLY after they have read it and told you they agree. Requires their full name as they typed it; recorded with this connection. Admin or manager only.
get_team_profileThe team profile the crew works from: company name as spoken, what the team sells, trademarks and how to say them, tone, how calls open and close, words to use and never use, house rules, the knock line, caller-ID name, and per-campaign overrides. Read it first; if is_set is fal…
draft_team_profileDraft a team profile from the company's website and any notes from your person. Returns a draft and its sources; nothing is saved. Walk your person through it — name as spoken, product names, tone, words to use and avoid, house rules, the knock line — and save what they approve…
set_team_profileSave the team profile (admin only). Pass only fields your person approved: spoken_name, pronunciation, about, website, trademarks [{name, say_as}], tone, opening, closing, say [], never_say [], customs (house rules, prose), knock_line ({name} = crew member's first name, {team} =…
set_campaign_customsOverride customs for one campaign (admin only): tone, opening, closing, say, never_say, customs, knock_line. For a campaign that should sound different from the team default — another market, region or offer. Null returns a key to the team default.
rename_crew_memberRename a crew member for the team's culture or region, optionally with a new voice, persona or greeting. Admin only; paid workspaces (402 otherwise — buy_credits first). Keys from list_team's crew or onboarding_status.
search_numbersAvailable US numbers by area code, for the crew's lines.
buy_numberBuy a number: $3/month from prepaid credits (first month charged now). Default is a crew line, and a crew member is put on it right away; for:"me" makes it your person's own caller ID instead. Admin or manager only. Confirm with your person before buying.
hire_crewPut an AI crew member (name, voice, role) on every free phone line so the crew can dial. Run after a number is bought.
set_mobileSet the mobile that rings when the crew reaches a person (get_a_human). Yours by default; managers can set a teammate's with user_id (from list_team).
buy_creditsA Stripe Checkout link your person opens to add credits by card ($20–$10,000). Agents with a wallet can use top_up_credits instead.
connect_salesforceA link your person opens to approve Bullpen in Salesforce, so every call writes there. Admin or manager only.
connect_googleA link your person opens to approve Google Calendar and Gmail, for booking meetings and sending mail.
invite_teammateInvite someone to the workspace by email; they get a sign-in link that lands on the join page. Roles: rep, manager, admin (only admins invite admins).
list_teamMembers (role, whether their mobile is set, Herman on) and pending invites with their links.
watch_companiesAdd companies to Social Intel, which scans them for buying and risk signals.
