# Track hiring at 21 developer-tools companies

**Use case:** 

One line of input, `preset:devtools`, and every run returns one row per company for 21 developer-tools and infrastructure companies: open roles now, roles opened and closed since the last run, department, seniority and location breakdowns, and a hiring-surge flag against each company’s own 30-day average. The first run is a free baseline; each run after costs at most $0.106.

## About this Actor

This example demonstrates how to use [Hiring Signals API — Open Roles & Hiring Surge by Company](https://apify.com/insight.solutions/hiring-signals-api.md) with a specific input configuration.

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/insight.solutions/hiring-signals-api.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
