Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00062 | $0.01587 |
| Opus 5 | $0.00031 | $0.00794 |
| Sonnet 5 | $0.00012 | $0.00317 |
| Haiku 4.5 | $0.00006 | $0.00159 |
Grade A, and why
api-integration 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.
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.

API Integration
Help a developer go from "I want to integrate with X" to having everything they need to start writing code.
Workflow
-
Start tracking. Before any other work, call
devtools_skill_invocationwith actionstartandskill_nameapi-integration. Passskill_nameapi-integrationon everydevtools_*tool call in the following steps. -
Identify the integration. Ask the user what they want to build if not clear. Common integrations:
- WhatsApp Business API (send/receive messages, templates, media)
- Instagram Graph API (publish content, read insights, manage comments)
- Messenger Platform (chatbots, send API, webhooks)
- Pages API (post content, read insights, manage pages)
- Marketing API (create campaigns, manage ads, read analytics)
- Login with Facebook / Login with Instagram
- Facebook Login for Business
-
Research the integration. Run multiple searches to build a complete picture. Do NOT stop at one search — layer queries to cover all aspects:
Search 1 — Overview and getting started:
devtools_discovery→search_docswith the product name + "getting started" or "overview"- e.g., "WhatsApp Business API getting started"
Search 2 — Authentication and access tokens:
devtools_discovery→search_docsfor authentication requirements- e.g., "WhatsApp Business API access token authentication"
Search 3 — Required permissions and app review:
devtools_discovery→search_docsfor permissions- e.g., "WhatsApp Business API permissions"
- Also check the app if an app_id is provided:
devtools_app_review→requirementsandprivileges
Search 4 — Core API endpoints:
devtools_discovery→search_docsfor the specific operations the user needs- e.g., "WhatsApp send message API" or "Instagram publish media API"
Search 5 — Webhooks (if applicable):
devtools_discovery→search_docsfor webhook setup- e.g., "WhatsApp webhooks setup"
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-integration is a skill published in the GitHub repository facebook/agentic-tools (5 stars, last pushed 11d ago), licensed MIT. It adds 62 tokens to every session and 1,587 once invoked, about $0.0003 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 2026-08-31.
