A 9-scene animated walkthrough — install, configure PIAPI_API_KEY, CLI tour, model catalog, async submit/poll/result flow, and per-agent skill paths. Built with Remotion; edit and re-render from presentation/remotion-tutorial/.

Install

curl -fsSL https://raw.githubusercontent.com/wesleysimplicio/PiAPI-Skills/master/install.sh | bash

Or clone and run:

git clone https://github.com/wesleysimplicio/PiAPI-Skills.git
cd PiAPI-Skills
./install.sh

Flags:

./install.sh --yes # non-interactive
./install.sh --agents claude,codex,hermes # install only listed agents
./install.sh --uninstall # remove CLI + agent skills

The installer:

1. Provisions a Python 3.10+ virtualenv at ~/.local/share/piapi-skill/venv and installs requests.
2. Drops piapi-cli into ~/.local/bin (add to PATH if missing).
3. Copies the appropriate SKILL.md into each detected agent skill root.

Agent skill paths the installer writes to:

Agent	Path
Claude Code	~/.claude/skills/piapi/SKILL.md
Codex	~/.codex/skills/piapi/SKILL.md
Hermes	~/.hermes/skills/creative/piapi/SKILL.md
OpenClaw	~/.openclaw/skills/piapi/SKILL.md
Cursor	~/.cursor/skills/piapi/SKILL.md
Windsurf	~/.windsurf/skills/piapi/SKILL.md
Generic	~/.config/agents/skills/piapi/SKILL.md

Configure

Set the API key from https://piapi.ai/workspace/key:

export PIAPI_API_KEY="<your key>"# optional, only if you receive webhooks:export PIAPI_WEBHOOK_SECRET="<your shared secret>"

Persist in your shell rc (~/.zshrc, ~/.bashrc).

CLI tour

piapi-cli --help # subcommand list
piapi-cli models # list known model · task_type pairs
piapi-cli imagine "studio portrait, calico cat" --aspect 1:1 # Midjourney imagine
piapi-cli flux "cyberpunk alley at night"# Flux schnell txt2img
piapi-cli kling --image-url https://… --prompt "slow zoom"# Kling image2video
piapi-cli suno --prompt "lofi piano under rain"# Suno music
piapi-cli faceswap --target-image https://… --swap-image … # Faceswap (image)
piapi-cli submit --model <m> --task-type <t> --input '{...}'# generic submit
piapi-cli wait<task_id># poll until terminal
piapi-cli result <task_id># fetch one snapshot
piapi-cli cancel <task_id># cancel pending only
piapi-cli run --model <m> --task-type <t> --input '{...}'# submit + wait + print
piapi-cli llm --model gpt-4o-mini --message 'user:Hi'# sync chat completion
piapi-cli verify-webhook --header-secret X --expected Y # constant-time compare

Add --webhook-url and --webhook-secret to any submit-style command to register a callback.

Status enum drift

Lowercase before comparing. Staged (Midjourney) is not terminal — follow up with upscale / variation. Treat completed | complete | success | succeeded as terminal-success and failed | failure | error | canceled | cancelled | rejected as terminal-failure.

Webhooks

PiAPI does not sign payloads with HMAC. The secret you registered on the task is echoed in the x-webhook-secret request header. Constant-time compare against your stored secret.

Retry policy: every 5s, up to 3 attempts on any non-2xx. After three failures, recover by polling piapi-cli result <task_id>.
