    Median latency 55 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 55 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 16

fathom_clear_event_currency

Remove the currency set for an event, so it uses the site's default again. The event and its completion data stay. Needs a manage token for the site. DELETE /sites/{site_id}/events?name=.

Discovered
fathom_create_milestone

Add a milestone (a dated annotation shown on the site's reports, e.g. a launch or campaign start). Needs a manage token for the site. POST /sites/{site_id}/milestones.

Discovered
fathom_create_site

Create a new site in the Fathom account (returns its id, used in the tracking code). Needs an Admin token. Sharing private needs share_password; multi_domain true needs multi_domain_option. POST /sites.

Discovered
fathom_delete_milestone

Permanently delete a milestone (only the annotation; traffic data is not touched). Cannot be undone. Needs a manage token for the site. DELETE /sites/{site_id}/milestones/{milestone_id}.

Discovered
fathom_get_account

The Fathom account that owns the API token: id, name and email. Needs an Admin token (the * scope). GET /account.

Discovered
fathom_get_aggregation

Fathom's custom report (the dashboard's numbers): aggregate pageviews or one event over a date range, optionally grouped by date and/or fields and filtered. Pageviews: aggregates visits (unique site visits), uniques (unique page visits), pageviews, avg_duration (seconds), bounce_rate. Events (entity event + event_name): conversions, unique_conversions, value (in cents). Examples: top pages = field_grouping [pathname], sort_by pageviews:desc; traffic sources = [referrer_source] or [referrer_hostname]; AI referrals = [ai_source]; daily trend = date_grouping day. All numbers come back as strings. Dates are in the site's timezone; hour grouping only for ranges up to 7 days. Grouped reports return at most 500 rows unless limit is set (max 1000, no paging), so narrow with filters or dates. Data before March 2021 cannot be grouped/filtered. GET /aggregations.

Discovered
fathom_get_current_visitors

Live visitors on a site right now: the total, and with detailed true the top 150 pages (hostname, pathname, total) and top 150 referrers. GET /current_visitors.

Discovered
fathom_get_milestone

One milestone: id, name, milestone_date, created_at, updated_at. GET /sites/{site_id}/milestones/{milestone_id}.

Discovered
fathom_get_site

One site: id, name, sharing (none/private/public), timezone and created_at. GET /sites/{site_id}.

Discovered
fathom_get_token

The connected API token's name, permissions (abilities: "*" = Admin, "all-sites-readonly", or per-site read:<id> / manage:<id>) and timestamps. The secret value is never returned. Good first call to know which tools will work. GET /token.

Discovered
fathom_list_events

List a site's events (conversions/goals): every event name the site has tracked plus events with a currency set, sorted by name. Identify events by name (use it as event_name in fathom_get_aggregation); the id is only a paging cursor. Paged: pass next.starting_after. GET /sites/{site_id}/events.

Discovered
fathom_list_milestones

List a site's milestones (dated annotations on reports, such as a redesign launch or a campaign start), oldest first. Paged: pass next.starting_after. GET /sites/{site_id}/milestones.

Discovered
fathom_list_sites

List the sites the token can read (id, name, sharing, timezone, created_at), oldest first. The site id is what every report tool takes. Needs an Admin or all-sites read-only token; a token scoped to a single site cannot list sites, so use fathom_get_site with that site id instead. Paged: pass next.starting_after. GET /sites.

Discovered
fathom_set_event_currency

Set the currency of an event's value by event name (works before the event is first tracked). Needs a manage token for the site. POST /sites/{site_id}/events/currency.

Discovered
fathom_update_milestone

Rename or re-date a milestone (both name and milestone_date are required). Needs a manage token for the site. POST /sites/{site_id}/milestones/{milestone_id}.

Discovered
fathom_update_site

Change a site's name, sharing, timezone or multi-domain setting (send only what changes). Changing the timezone changes how reports are bucketed. Needs a manage token for the site. POST /sites/{site_id}.
