Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill failed 1 of 6 checks. A failure is not proof of bad intent; it means something in the code needs a human to look at it before you run it.

  • No undeclared network calls: failed

    Contacts 4 hosts that are neither well-known infrastructure nor declared in the skill's frontmatter: api.bfl.ai, api.eu.bfl.ai, api.us.bfl.ai, dashboard.bfl.ai.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

About this skill

What it does

This skill provides guidance and assistance for integrating Black Forest Labs (BFL) FLUX APIs into applications that generate, edit, or process images. It offers information on API endpoints, pricing models, and best practices for building production-ready integrations with BFL's image generation services. The skill helps users set up their API client, handle rate limits, and configure webhooks.

When to use it

  • Setting up a BFL API client within an application.
  • Implementing asynchronous polling patterns when interacting with the APIs.
  • Managing rate limits and handling potential errors during API calls.
  • Configuring webhooks for production environments.
  • Choosing appropriate regional endpoints (Global, EU, US) based on requirements like GDPR compliance or data residency.

Key capabilities

  • Provides information on BFL API base endpoints for different regions (Global, EU, US).
  • Details pricing models and costs associated with various FLUX.2 and FLUX.1 models.
  • Outlines model paths for image generation and editing tasks.
  • Offers guidance on handling temporary image URLs that expire after 10 minutes.
  • Explains how to use the input_image parameter for image editing within FLUX.2 models.

Example prompts

  • "What are the available regional endpoints for the BFL API?"
  • "How much will it cost to generate an image using the FLUX.2 [pro] model at a resolution of 1000x1000 pixels?"
  • “Show me an example curl command for editing an image with the FLUX.2 pro model.”

Tips & gotchas

  • API Key: Ensure your BFL_API_KEY environment variable is set before using the API, as authentication errors will occur otherwise.
  • Image URL Expiration: Downloaded images from the BFL API are only available for a short time (10 minutes). Download them immediately after generation and avoid caching the URLs themselves.
  • Pricing: Use the bfl.ai/pricing calculator to accurately determine costs based on image resolution.
