Checking your claim link…
This key is shown only once. It is not stored anywhere we can show it again — copy it now and keep it secret. It is also filled into the usage panel below for this browser tab.
Your model key
A capped key for the model API, so the examples cookbook runs with no other signup. Prefer your own provider? Point it at that with AGENT_NEXT_BASE_URL instead.
Also shown only once. Copy it now and keep it secret.

No model key was left in the beta pool — the sandbox key above works on its own.
Get an API key
Sign in with GitHub for an instant key on the free tier — one account per GitHub user, no card needed. Card verification is not open yet (GET /v1/tiers reports card_verification_enabled), so every self-serve key is on the free tier for now; once it opens, a $0 card check (no charge) moves an account to the larger verified tier. No GitHub account? Join the waitlist with just an email address. Already approved from the waitlist? Open your claim link.

Usage
Paste your API key to see your credit and sandboxes. It stays in this tab (sessionStorage) and is sent only to the API.
Tier: –
Verify a card to move to the verified tier. Stripe checks it with a $0 setup — nothing is charged. A card can upgrade one account.
Sandboxes
| ID | Template | State | Started | Action |

No running or paused sandboxes.
Quickstart
export E2B_DOMAIN="sbx.agent-next.com"
export E2B_API_KEY="<your key>"
python -c "from e2b import Sandbox; print(Sandbox.create().commands.run('uname -a').stdout)"More in the quickstart. GPU sandboxes have the same three entrances — REST, the sbx CLI's gpu verbs, and the MCP tools: GPU guide, "Three ways in".
