Casebook

Job-market questions, answered on the API, with the bill attached.

AI agents answer them on the Metix AI Platform, a data API for professional profiles, job postings, and companies that agents reach through MCP, skills, or REST. Each case publishes the finding, the queries behind it, what it cost, and the prompt that produced it.

The whole walk-through6 API Credits$0.20Fits in the 100 free API Credits

  1. 1Get a key

    Free: 100 API Credits

    New accounts get 100 API Credits once, valid for 30 days. Set the key in the shell you start your agent from, or add the line to ~/.zshrc or ~/.bashrc so every new terminal has it:

    Shell
    export METIX_KEY=metix_xxxxxxxx
    Create a key on the Metix AI Platform →

    No card. The key is shown once: paste it in place of metix_xxxxxxxx.

  2. 2Connect your agent

    One command, once

    Pick the agent you use. Each tab gives the one step that connects it to the Metix AI Platform.

    Claude Code

    Registers the Platform for every project. Start claude in any folder and the ten metix tools are there.

    Shell
    : "${METIX_KEY:?run step 1 first}" &&
claude mcp add --scope user --transport http metix \
  https://mira-api.metix.ai/mcp \
  --header "Authorization: Bearer $METIX_KEY"

    Codex

    Registers the same server. The key stays in your environment instead of the config file.

    Shell
    codex mcp add metix \
  --url https://mira-api.metix.ai/mcp \
  --bearer-token-env-var METIX_KEY

    Skills

    Four skills that teach any agent the Platform's endpoints and query rules, for agents without MCP. The installer starts with none ticked: press space on each, then enter.

    Shell
    npx skills add MetixAI-Official/metix-skills
    Skills install guide →

    Other MCP

    Point the client at this endpoint over streamable HTTP with both headers; without the Accept header the server answers 406. Older clients use /sse on the same host.

  3. 3Check the setup

    Free: no search runs

    Ask this first. It reads your balance and the field list, runs no search, and costs nothing:

    Prompt for your agent
    Use the Metix AI Platform to check my key status and read the contract; both are free. Then tell me my API Credit balance and which datasets I can query. Do not run any search.
