# Credits

> API credit costs per endpoint, pricing plans (Free, Pro, Scale), and usage monitoring. Most endpoints cost 1 credit; live detection costs 5.

Every API call uses credits from your plan balance. Different endpoints cost different amounts depending on the compute involved.

## How much does each endpoint cost?

<Info>
  Most endpoints cost 1 credit. Live detection (5 credits) costs more due to real-time browser rendering.

## How to monitor usage

Use the account endpoints to track your credit consumption:

* **`GET /v1/credits`** — Current credit balance across all API keys
* **`GET /v1/usage`** — Detailed usage statistics with date range filtering

Both endpoints are free and don't consume credits.

## Frequently asked questions

<AccordionGroup>
  <Accordion title="Do unused credits roll over to the next month?">
    No. Credits reset monthly on your billing cycle date. Unused credits don't carry over. Monitor your balance with the free `GET /v1/credits` endpoint to avoid waste.
  </Accordion>

  <Accordion title="What happens when I run out of credits?">
    API calls that require credits will return an error when your balance reaches zero. Free endpoints like `/v1/usage` and `/v1/credits` continue to work. Upgrade your plan or wait for the monthly reset.
  </Accordion>

  <Accordion title="Why does live detection cost more than a database lookup?">
    Live detection (`POST /v1/technology-lookup-live`) costs 5 credits because it spins up a real-time browser session to render the page, execute JavaScript, and analyze the results. Database lookups use pre-crawled data and return instantly for 1 credit. Use the [domain lookup](/docs/api-reference/introduction#domain-technologies) first and fall back to live detection only when needed.
  </Accordion>

  <Accordion title="How are credits counted for batch requests?">
    Batch endpoints charge 1 credit per item in the request. For example, `POST /v1/companies/batch` with 50 domains costs 50 credits. `POST /v1/technologies/lookup` costs 1 credit total regardless of how many technology names you include. Check the [endpoint table](/docs/api-reference/introduction#available-apis) for per-endpoint costs.
  </Accordion>

  <Accordion title="How do I check my remaining credits programmatically?">
    Call `GET /v1/credits` to get your current balance, credit limit, and next reset date. This endpoint is free and doesn't consume credits. You can poll it from your application to build dashboards or trigger alerts before you run out. See the [account API](/docs/api-reference/endpoints/account) for details.
  </Accordion>

  <Accordion title="Is there an enterprise plan with custom credit limits?">
    Yes. If the Scale plan's 50,000 monthly credits aren't enough, contact the TechnologyChecker team for custom enterprise pricing. Enterprise plans include higher credit allocations, increased rate limits, and dedicated support. Visit [technologychecker.io](https://technologychecker.io) to get in touch.
