Configure Fathom AI meeting assistant API access with API key authentication.

  • Works in 4 steps: Generate API Key → Configure Environment → Test API Connectivity → …
  • Setting up Fathom API integration
  • SKILL.md covers Output, Examples, Overview and Prerequisites, plus 4 more sections
  • Calls curl and jq; reaches api.fathom.ai; needs FATHOM_API_KEY

What it does

Fathom Install Auth is an agent skill from jeremylongshore/tons-of-skills-marketplace. Configure Fathom AI meeting assistant API access with API key authentication. Use when setting up Fathom API integration, generating API keys, or configuring webhook access for meeting data. Trigger with phrases like "install fathom", "setup fathom api", "fathom auth", "fathom api key", "configure fathom".

Its SKILL.md is about 820 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Designed for Claude Code

It sits in Backend & APIs, covering Third-party API integration and Webhooks. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Setting up Fathom API integration
  • Generating API keys
  • Configuring webhook access for meeting data
  • With phrases like install fathom

Example prompts

  • “install fathom”
  • “setup fathom api”
  • “fathom auth”
  • “/fathom-install-auth”

Requirements

  • A credential in FATHOM_API_KEY
  • Compatibility (from SKILL.md): Designed for Claude Code
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Bash(curl:*), Grep

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Generate API Key
  2. Configure Environment
  3. Test API Connectivity
  4. OAuth Setup (For Public Apps)

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Write
    • Edit
    • Bash(curl:*)
    • Grep

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl
    • jq

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • api.fathom.ai

    Also links to:

    • developers.fathom.ai
    • fathom.video
    • help.fathom.video

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • FATHOM_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Designed for Claude Code

    From compatibility in the SKILL.md frontmatter.

Context cost

Fathom Install Auth loads about 818 tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 227 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~82
When it runs · the whole SKILL.md, loaded when a task matches
~818

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:65
    # .env -- NEVER commit
  • NoteMentions a .env fileSKILL.md:70
    .env
  • NoteMentions a .env fileSKILL.md:71
    .env.local

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Fathom Install & Auth

Output

  • A scoped Fathom credential/integration reference for the intended environment, with a verified low-impact connection test.
  • A credential ownership, rotation, and revocation path that protects meeting content and contacts.

Examples

Configure a development credential from the approved secret manager and verify access against a synthetic meeting/test account, recording only environment and result. If a token appears in code, logs, or support material, revoke it immediately and issue a replacement before further diagnosis.

Overview

Set up Fathom AI API access for retrieving meeting transcripts, summaries, and action items. The API at api.fathom.ai/external/v1 uses X-Api-Key header authentication with per-user API keys.

Prerequisites

  • Fathom account (free or Team plan)
  • API access enabled in Settings

Instructions

Step 1: Generate API Key
  1. Log in to https://fathom.video
  2. Navigate to Settings > Integrations > API Access
  3. Click Generate API Key
  4. Copy and store the key securely
bash
export FATHOM_API_KEY="your-api-key-here"

# Verify the key works
curl -s -H "X-Api-Key: ${FATHOM_API_KEY}" \
  https://api.fathom.ai/external/v1/meetings?limit=1 | jq .
Step 2: Configure Environment
bash
# .env -- NEVER commit
FATHOM_API_KEY=your-api-key
FATHOM_BASE_URL=https://api.fathom.ai/external/v1

# .gitignore
.env
.env.local
Step 3: Test API Connectivity
bash
# List recent meetings
curl -s -H "X-Api-Key: ${FATHOM_API_KEY}" \
  "https://api.fathom.ai/external/v1/meetings?limit=5" \
  | jq '.meetings[] | {id: .id, title: .title, date: .created_at}'
Step 4: OAuth Setup (For Public Apps)
bash
# For building integrations others will use, register an OAuth app
# at developers.fathom.ai for marketplace listing eligibility

# OAuth apps cannot use include_transcript or include_summary
# in list requests -- use individual recording endpoints instead
