## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ghostkey-delegation-session-creator-0b516624 -d '<json body>'
```

Example prompt: Create a GhostKey delegation session scoped to my origin so I can run unmetered browser actions without paying per step.

## When to prefer this

Choose this endpoint when you need to perform many browser actions against a single origin and want to avoid per-action metering costs. It is ideal for agentic browser automation workflows where a single session can amortize the fixed $0.1 USDC minting cost across many unmetered steps. Prefer this over per-call browser APIs when the number of actions per session exceeds one.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment not accepted, resulting in 402 error
- Invalid origin: origin parameter missing or malformed, session cannot be scoped
- Session creation conflict: duplicate or overlapping session for same origin
- Server unavailable: render.com cold-start latency or downtime causing timeout
- Expired credentials: upstream auth token used to create session has already lapsed

## How this service works

GhostKey delegation session (ghostkey_session_create): mint a short-lived, origin-scoped browser delegation session. Actions inside a minted session are unmetered.

## Output

Returns a minted delegation session object including a session token or ID, origin scope binding, and expiry metadata. Actions performed within the session are unmetered, meaning no additional per-call charges apply until the session expires.
