Credits for built-in tools. Know the price before your AI acts.
Obol runs a few tools itself, so your AI can search the web, read a page, or create and read images without you opening another account. Each use costs a fixed number of credits, and 1 credit is $0.01.
Built-in tools are rolling out to Obol Cloud. The prices below are already published.

Who bills itObol-operated compute, metered from running to release. No rate is published yet.
1 credit = $0.01Obol runs open-source software where it can, and pays for a hosted API on its own account only where that costs less. Each built-in tool above names its source and license.
How credits work. Included first, then prepaid, then they stop.
Included credits each month, shared across your organization.
- Free
- 100 credits
- Team
- 2,000 credits
They refill on the first of each month (UTC).
Then your prepaid credit balance.
If you have one, built-in calls draw on it once the month’s included credits are used.
No automatic overage.
When both run out, built-in calls stop. Nothing is billed afterwards.
- Counts toward your plan
- Each built-in call also counts as one tool call in your plan’s monthly allowance.
- Tools that create something
- “Generate an image” waits for your OK in production unless your rules allow it, and counts as a write and a destructive call as well as a tool call.
- Workspaces you already had
- Workspaces that existed before built-in tools start with them off until an admin turns them on.
- Free Self-hosted
- Built-in tools aren’t part of Free Self-hosted, and the self-host bundle doesn’t include the service that runs them. A self-hosted Obol never charges credits: it records any built-in call as
not_chargeable.
Questions about credits, answered plainly.
Each plan’s price and monthly limits are in the pricing section.
Credits are how Obol prices its built-in tools: 1 credit is $0.01. A web search costs 1 credit and an image costs 2 credits, so Free’s 100 included credits cover up to 100 searches or 50 images a month, and Team’s 2,000 cover up to 2,000 searches.
When your included credits and any prepaid balance are used up, built-in calls stop until the included credits refill on the first of the month (UTC). Nothing is billed automatically, and your other actions carry on under your plan. Unused credits don’t roll over, and adding workspaces doesn’t add more: one allowance is shared across your organization.
No. Credits pay Obol, never the apps you connect. Stripe, Gmail, your own OpenAI or Anthropic account and the rest bill you directly, at your rate, and Obol adds no markup to those bills.
Yes. An admin can turn them on or off for each workspace at any time. When they’re on, your AI can still use only the built-in tools your rules allow. A rule that allows every action allows these too, so check your rules before you turn them on.
To the source named beside each tool above: open-source software Obol runs, or a hosted API Obol pays for. A search through SearXNG also reaches the search engines it asks. If that doesn’t suit you, leave built-in tools off, or leave them out of your rules.
