E2B runs hosted sandboxes for AI agents and bills each running sandbox per second for its vCPU and memory. CostGraph reads E2B as FOCUS 1.2 records at a grain of one record per running sandbox per day. Spend is estimated from E2B’s published prices and can differ from your invoice. Only sandboxes still running when we read are seen.

​
Choose how the data reaches us

CostGraph pulls it

You supply read-only credentials and we call E2B once a day. Nothing to run.

You push it

You send us FOCUS records over the API. Credentials never leave your infrastructure.

​
Before you begin

  • In the E2B dashboard, open Keys and create a team API key.
  • Copy the team id from Team settings. The key cannot look it up itself.
  • The connect form links to the page where you create this credential.

​
Let CostGraph pull

  1. Open Settings > Integrations and pick E2B.
  2. Name the connection and pick the tenant these charges belong to.
  3. Enter the values you copied. The form lists what E2B needs and marks the optional ones.
  4. Select Connect.
CostGraph verifies the credentials with a short fetch before saving, so a wrong value or a missing permission fails while you are still on the form.
Credentials are encrypted at rest and used only to read billing data. Revoke them in E2B at any time and the connection stops; nothing else is affected.

​
Push it yourself

Send the charges to CostGraph as FOCUS records instead. Push FOCUS data covers the connection id, the focus:write key, and the request shape.

​
Run the exporter

Your E2B credential stays where you put it, and only the finished FOCUS records reach CostGraph. Run the exporter covers the three ways to run it and the variables it reads.

​
What CostGraph does with it

Records land as raw billing rows, are normalised into line items, and roll up into daily cost. From there E2B spend appears in Cost Overview and in anomaly detection alongside every other provider.

Managed sandboxes

The same E2B account can run CostGraph code changes. See Managed sandboxes.
