01 / Outcome

What this service does

One paid create returns a fixed ten-minute lease. Connect with ordinary CDP, then close it or let it expire.

Best for

Agents that need a clean remote Chromium session without a browser platform account or proprietary automation API.

Returns

A session identity, hard expiry, and private bearer capability for status, CDP connection, and close.

02 / Price

One clear Ausca price.

The catalog defines the range. Live preparation or the payment challenge returns binding terms.

Ausca price

Start from the exact versioned instructions for this service. The skill describes the capability, inputs, payment boundary, retry identity, and evidence without requiring an agent to scrape this page.

Expected first response: 402 with matching x402 v2 PAYMENT-REQUIRED header and body. A valid paid retry returns the admitted or replayed invocation.

MCP Discovery and control

MCP projects the same Ausca contract. Paid invocation is disabled by default and must be enabled deliberately by a compatible host. MCP does not carry x402 HTTP headers.

Expected response: the generated invocation result shape. Use ausca_get_invocation for authoritative state and the receipt reference.

05 / Lifecycle

One purchase identity to terminal state.

The purchase creates one replay-safe lease. Lifecycle calls inside the lease do not charge again.

01 payment terms
02 lease ready
03 CDP connected
04 closed or expired

Mint a single-use connection URL when the lease is ready. It expires after 60 seconds and admits one live CDP client.

Close is idempotent. Hard expiry ends access immediately while provider cleanup continues safely if it needs a retry.

06 / Contract examples

A complete request, from authority.

The offer has no caller-selected input. Keep the same idempotency key when retrying an uncertain purchase.
