Performance

  • Not measured
    Fast (p50)

    Median latency 177 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 177 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

Capabilities

Tools 25

fub_add_note

Add a note to a contact's timeline. FUB: POST /v1/notes.

Discovered
fub_check_duplicate_person

Check if a contact with this email or phone already exists anywhere in the account (even ones this user cannot see) and who it is assigned to. Use before adding a lead. FUB: GET /v1/people/checkDuplicate.

Discovered
fub_create_deal

Create a deal in a pipeline stage (stage ids from fub_list_pipelines). Include userIds — a deal with no users is invisible to agents. FUB: POST /v1/deals.

Discovered
fub_create_task

Create a task on a contact, assigned to a user (assignedUserId or assignedTo is required). FUB: POST /v1/tasks.

Discovered
fub_get_identity

Who the credential belongs to: the account (id, domain, owner) and the authenticated user. A cheap way to confirm the API key works. FUB: GET /v1/identity.

Discovered
fub_get_person

Fetch one contact by id. Pass fields="allFields" to include custom fields and everything else. FUB: GET /v1/people/{id}.

Discovered
fub_lead_source_report

Count leads from lead sources (e.g. Zillow) per assigned agent, how many reached the closed stage(s) (conversion rate), and leads per lender user (e.g. Zillow Home Loans loan officers). Use it to count instead of paging through fub_search_people. The numbers approximate FUB's in-app Lead Source report, which has no API, not the Zillow Preferred or Zillow Home Loans dashboard metrics (including pre-approvals), which are not exposed by the public API, and cover only the people the API key can see (use an owner, admin or broker key for the whole account). At most 100 FUB requests per call (one per count). FUB: GET /v1/people totals, GET /v1/users.

Discovered
fub_list_action_plans

The account's action plans (drip campaigns): id, name and status. Gives the names for the actionPlanId values of fub_list_person_action_plans. FUB: GET /v1/actionPlans.

Discovered
fub_list_appointments

Calendar appointments with invitees, type and outcome. Filter by person, user, or a start+end window (both required together). FUB: GET /v1/appointments.

Discovered
fub_list_calls

Logged phone calls with outcome, direction and duration. Filter by person or number. FUB: GET /v1/calls.

Discovered
fub_list_custom_fields

The account's contact custom fields: label, API name (customXxx), type and dropdown choices. Use the name as a key in customFields. FUB: GET /v1/customFields.

Discovered
fub_list_deals

Deals (transactions) with stage, price, people, agents and commission. Filter by pipeline, user, person or status. The response metadata includes totalByStageId. FUB: GET /v1/deals.

Discovered
fub_list_events

Lead activity: registrations, inquiries, viewed/saved properties, website visits, etc. Filter by person or type. Some events are only visible in the FUB app. FUB: GET /v1/events.

Discovered
fub_list_person_action_plans

Which people are on which action plan, with the status of each assignment (e.g. "Running", "Paused"). Give personId for one contact's plans, or actionPlanId for everyone on one plan. For many contacts, list each active plan's people (limit 100; page with offset until _metadata.total is covered) instead of one call per contact. Shows classic action plans only; Automations 2.0 are in fub_list_person_automations when that tool is listed. FUB: GET /v1/actionPlansPeople.

Discovered
fub_list_pipelines

Deal pipelines with their stages (the stage ids that fub_create_deal / fub_update_deal take). FUB: GET /v1/pipelines.

Discovered
fub_list_stages

Contact lifecycle stages (Lead, Nurture, Past Client, Trash…) with people counts — the names fub_search_people and fub_update_person take as "stage". FUB: GET /v1/stages.

Discovered
fub_list_tasks

Tasks (follow-ups, calls, showings…). Filter by person, assignee, type, completion, or due window (due="today"|"overdue"|"upcoming"). FUB: GET /v1/tasks.

Discovered
fub_list_text_messages

Text messages for a person or a phone number (message bodies may be hidden by FUB for privacy). FUB: GET /v1/textMessages.

Discovered
fub_list_users

Users in the account (agents, brokers, lenders) — the ids to assign people, tasks and deals to. FUB: GET /v1/users.

Discovered
fub_log_call

Record a phone call made or received outside FUB, with its outcome. Does not place a call. FUB: POST /v1/calls.

Discovered
fub_search_people

Search contacts and leads. Criteria combine with AND. Name filters are partial matches. Newest first by default. People in the Trash stage are excluded unless includeTrash is true. Not every field is returned by default — pass `fields` (e.g. "allFields" or a comma list) for more. FUB: GET /v1/people.

Discovered
fub_send_lead_event

Add a new lead or record activity on an existing one — FUB's documented way to create leads. FUB de-duplicates by email/phone (or use person.id to target a contact), routes the lead per Lead Flow, notifies the agent and runs action plans for Registration / Inquiry types. A 204 means the lead flow for this source is archived and the event was ignored. FUB: POST /v1/events.

Discovered
fub_update_deal

Update a deal — move it to another stage, change price, dates, people or agents. peopleIds/userIds replace the full list. FUB: PUT /v1/deals/{id}.

Discovered
fub_update_person

Update a contact's fields. CAUTION: `tags` REPLACES all tags unless mergeTags is true; `phones` and `emails` REPLACE the full list (send existing ones too). Setting contacted=true pauses action plans. source/sourceUrl cannot be changed after creation. FUB: PUT /v1/people/{id}.

Discovered
fub_update_task

Update a task — mark it complete, rename, retype or reassign it. FUB: PUT /v1/tasks/{id}.
