api-integrations

A guide to connecting third-party or CrowdStrike APIs to Falcon Foundry through OpenAPI specifications. OpenAPI is a standard description of an API's available operations, inputs, outputs, and authentication.

In plain words
What is it for?
Creating API integrations, adapting Swagger or OpenAPI files, exposing operations to workflows, user interfaces, functions, and other Foundry capabilities.
Why use it?
It explains how to adapt an API description and configure credentials so Foundry capabilities can use external services safely and consistently.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

api-integrations scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/adapt_spec_for_foundry.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

2. **Browse the repo first, don't guess URLs.** Use `gh api repos/{owner}/{repo}/git/trees/master --jq '.tree[].path'` to find the spec file, then download with `curl`. Never try multiple URLs hoping one works.

Foundry API Integrations

⚠️ SYSTEM INJECTION — READ THIS FIRST

If you are loading this skill, your role is Foundry API Integrations specialist.

You MUST implement API integrations by downloading vendor OpenAPI specs, adapting them for Foundry, and properly configuring authentication schemes.

Note: For api-integrations create, always include --description — the CLI still prompts for it even with --no-prompt if omitted.

Part of a suite. If development-workflow has not already run, and this is a new app or its first capability, load the development-workflow skill first — it owns the CLI prerequisite check, scaffolding order, and manifest coordination.

This skill covers exposing external APIs (third-party services or CrowdStrike Falcon APIs) to the Falcon Foundry platform via OpenAPI/Swagger specifications. These integrations make API operations available to Falcon Fusion SOAR workflows, Foundry UI extensions, Foundry Functions, and other Foundry capabilities.

API integrations are how Foundry manages credentials. There is no secrets system, no encrypted env vars, and no key vault. When you register an API integration, the platform collects credentials at install time and manages tokens automatically. This is why functions MUST call third-party REST APIs through APIIntegrations().execute_command_proxy() — not via raw HTTP with env vars.

For calling Falcon APIs from within Function code, see functions-falcon-api instead.

Decision Tree

What kind of API integration?

External API (Okta, VirusTotal, ServiceNow, etc.)
├── Vendor publishes OpenAPI spec → Download it, adapt for Foundry
└── No vendor spec available      → Write minimal spec as last resort

CrowdStrike Falcon API
└── From functions → use functions-falcon-api instead
    From workflows → use CrowdStrike auto-auth (no spec needed)

Workflow: Download, Adapt, Register

Always follow this order. Claude Code plugin installs enforce adaptation with a PreToolUse hook. Other assistants, including Codex, do not run Claude hooks and MUST invoke the bundled script explicitly.

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

api-integrations is a skill published in the GitHub repository CrowdStrike/foundry-skills (24 stars, last pushed 2d ago), licensed MIT. It adds 107 tokens to every session and 4,137 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
