CheaperGen/skills

Agent Skills and a Claude Code plugin for CheaperGen, one API for official video and image models from the major labs (Seedance, Kling, Veo, Wan, MiniMax, FLUX, GPT Image, Nano Banana and more) at prices below the official list.
The repo has two parts:
The cheapergen skill (skills/cheapergen/SKILL.md) teaches an agent the CheaperGen REST API. It covers choosing a model, reading its input schema, quoting, submitting, polling or webhooks, @Image1-style reference mentions, uploads, pricing and errors. It works in any agent that supports Agent Skills.
The Claude Code plugin cheapergen bundles that skill with the hosted CheaperGen MCP server, https://cheapergen.com/api/mcp. The server's tools are list_models, get_model, quote (it also says whether your balance covers the job), generate, get_generation, upload_file (turns a local photo, video or audio file into an https URL to generate from; free), compare_prices (price against the official price and other API platforms; free), get_account (balance, and the account's API limits) and add_credits (a payment link the user opens when the balance is low). Finished images come back with a small inline preview in the chat. You sign in with your CheaperGen account in the browser, so there's no API key to paste.
The Claude Code plugin cheapergen-dev (cheapergen-dev/) is for developers integrating the API: the cheapergen-api skill (cheapergen-dev/skills/cheapergen-api/SKILL.md: API keys, endpoints, quotes, polling and webhooks, errors) plus the read-only CheaperGen Developer MCP server, https://cheapergen.com/api/mcp/dev. Its tools are list_models, get_model, quote and compare_prices (CheaperGen's live price against the official price and other API platforms, with the date each was checked and its source), with no sign-in; connected with an API key it also has get_account and quotes your own prices. It never generates media, spends credits or creates payments.
## Install
### Claude Code plugin (skill + MCP server)
/plugin marketplace add CheaperGen/skills
/plugin install cheapergen@cheapergen
Then run /mcp, select plugin:cheapergen:cheapergen and choose Authenticate. Sign in at cheapergen.com and approve the connection. From a terminal, the same steps are:
bash
claude plugin marketplace add CheaperGen/skills
claude plugin install cheapergen@cheapergen
### Claude Code plugin for developers (API skill + read-only MCP server)
/plugin marketplace add CheaperGen/skills
/plugin install cheapergen-dev@cheapergen
It works right away, without sign-in: it looks up models, prices, quotes and price comparisons. Your code generates through the REST API with an API key. To also see your own prices and balance in the connection, add it with that key instead:
claude mcp add --transport http cheapergen-dev https://cheapergen.com/api/mcp/dev --header "Authorization: Bearer $CHEAPERGEN_API_KEY"
### Skills CLI (Claude Code, Cursor, Codex, Gemini CLI and others)
bash
npx skills add CheaperGen/skills
Add -g to install for all projects, -a claude-code (or -a cursor, -a codex…) to choose the agent, and --skill cheapergen to skip the prompt. This installs only the skill. To add the MCP server too, see MCP setup.
