This file holds every use case of this repo. Each one starts with a "## " heading and ends with its URL. - Find the cheapest listed API for a model: https://dedupedai.com/use-cases/hanzohanzhe-grandet/find-cheapest-model-api/ - Find free credit for a model without a card: https://dedupedai.com/use-cases/hanzohanzhe-grandet/find-free-model-credit/ - Connect the cheapest API to your coding agent: https://dedupedai.com/use-cases/hanzohanzhe-grandet/connect-cheapest-api-to-agent/ - Pull the live price board into your own analysis: https://dedupedai.com/use-cases/hanzohanzhe-grandet/pull-price-board-into-analysis/ ## How to find the cheapest listed API for a model with Grandet Repo: [hanzohanzhe/Grandet](https://github.com/hanzohanzhe/Grandet) | Difficulty: Beginner | Time: 15 minutes | Basis: From the README Ask your agent for the lowest listed price for a model, with the site, group, unit and observation date. **Who it is for:** A developer paying for model API calls who needs the cheapest listed option for one model before committing budget. **The problem:** Model API prices differ across official APIs, inference providers and relay sites, and comparing them by hand takes time. **The outcome:** A short list of the cheapest few listed options for your model, each with its source and observation date, ranked by listed price only. ### Steps 1. Paste `Install Grandet Skill for me: https://grandet.ai/download.md` into your agent and let it finish the install. 2. Open a new conversation and ask for the cheapest API for your model, for example: Find me the cheapest Claude Sonnet 4.6 API. 3. Give your monthly token volume and input/output split if you want a monthly cost estimate. 4. Check the listed site, group, price, unit and observation date before you act on any result. ### Prompt to paste into your agent ```text Using the Grandet Skill or the MCP server at https://grandet.ai/mcp, find the cheapest listed API for . Return the top three options with site, group, price, unit and observation date, and confirm that prices are shown in one currency unit only. ``` ### Caveat Grandet ranks by listed price only and says nothing about quality, speed or downgraded models, so check that the option fits your needs.

Ask your agent: Is there a free API for ? I don't have a credit card. 2. Or query the HTTP free-credit lookup directly: `https://grandet.ai/api/v1/free-credits?q=gemini`, replacing gemini with your model or provider. 3. Read the card, ID check and application notes for each offer before signing up. 4. Open the source link for any offer you plan to use and confirm the terms on that site. ### Prompt to paste into your agent ```text Use the Grandet free-credit lookup at https://grandet.ai/api/v1/free-credits?q= to list free credit offers for . Return each offer with whether a card, ID check or application is needed, and flag any offer that needs a card. ``` ### Caveat Free offers and promotions change over time, so confirm current terms on the source site before you rely on one.

Sign up and top up on the site yourself, then create the token in the group Grandet names. 2. Run one command in your own terminal to store the key; typing is hidden and the key never enters the chat. 3. Ask your agent to connect the API to your app, and review the exact configuration change it shows you. 4. Confirm the change so the file is backed up and written, then let the check run. 5. Say undo if you want the previous setup restored. ### Prompt to paste into your agent ```text Using the Grandet Skill connect program for , connect the chosen API for . Show the configuration change before writing, confirm the backup was made, and report the result of the key, group and model name check. ``` ### Caveat Connecting covers only the apps Grandet names, such as Codex, Claude Code, OpenCode and Gemini CLI; other apps get only a field card and documentation link. Risk, credentials: You store a provider API key on your machine, so keep it out of chats, screenshots and issue reports. Risk, remote script: The Skill is installed from a URL, so review what the agent installs before you approve it. Disclaimer: Third-party repos we don't own or vouch for.

Fetch the price board: `https://grandet.ai/api/v1/board`. 2. Read the API description at https://grandet.ai/public-data/price-finder.json to learn the fields. 3. Keep the observation date and unit with each price so you never compare USD credit, CNY credit and cash prices directly. 4. Filter the rows to your models and build your cost comparison from them. ### Prompt to paste into your agent ```text Fetch https://grandet.ai/api/v1/board and read the field description at https://grandet.ai/public-data/price-finder.json. Produce a table of listed prices for with source, unit and observation date, and do not compare USD, CNY or cash prices with each other. ``` ### Caveat The board reflects listed prices only, so cross-check any figure against its source before using it in a budget.
