# Ausca Remote Browser Session Lease

> Ausca Remote Browser Session Lease is a paid API for AI agents from ausca.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-13).

## 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 ausca-remote-browser-session-lease-d2149419 -d '<json body>'
```

Example prompt: Spin up a remote browser session for 10 minutes so I can automate a checkout flow — I need a verifiable receipt when it's done.

## When to prefer this

Choose this endpoint when an AI agent needs on-demand, accountless, pay-per-use remote browser access with cryptographically verifiable receipts and explicit per-call pricing. Prefer over self-hosted browser infrastructure when you want zero setup, metered cost (only pay for sessions you open), and built-in x402 payment flow. Best for agents that need short bursts of web automation (10–60 min) without managing browser pools or provider credentials.

## Known failure modes

- Invalid duration_seconds value (must be 600, 1800, or 3600) — schema validation error
- Payment not received or insufficient USDC — 402 Payment Required
- Duplicate idempotency_key with mismatched parameters — conflict error
- Session provisioning backend unavailable — 503 or timeout
- Mismatched input_schema_digest or output_schema_digest — canonicalization mismatch error
- Expired or invalid offer_revision — offer not recognized

## How this service works

Lease one ordinary remote browser with standard CDP access for 10, 30, or 60 minutes. No automation, proxy, stealth, or target-success promise.

## Output

Returns a JSON object with status 'accepted', an invocation record containing the output resource_lease (schema ausca.browser_session.lease.v1) with a session_id (e.g. brs_...), created_at and expires_at timestamps, a verifiable receipt_ref URI, an invocation_id, and output and offer_revision digests for cryptographic verification.
