The daemon already progresses exits automatically in the background—use this endpoint when you want immediate progress rather than waiting for the next automatic cycle. On each call, the endpoint checks whether previously broadcast transactions have confirmed and, if so, creates and broadcasts the next transaction in the sequence. The on-chain wallet must have sufficient bitcoin to cover transaction fees. ## OpenAPI ````yaml https://gitlab.com/ark-bitcoin/bark/-/raw/master/bark-rest/openapi.json post /api/v1/exits/progress openapi: 3.1.0 info: title: barkd REST API description: >- A simple REST API for barkd, a wallet daemon for integrating bitcoin payments into your app over HTTP. Supports self-custodial Lightning, Ark, and on-chain out of the box. barkd is a long-running daemon best suited for always-on or high-connectivity environments like nodes, servers, desktops, and point-of-sale terminals. All endpoints return JSON. Amounts are denominated in satoshis. contact: name: Second Team email: hello@second.tech license: name: MIT identifier: MIT version: 0.1.4 servers: [] security: - bearer: [] tags: - name: boards description: Move on-chain bitcoin onto the Ark protocol. - name: exits description: Move bitcoin back on-chain without server cooperation. - name: fees description: Estimate fees for wallet operations before executing them. - name: lightning description: Create Lightning invoices and track receives. - name: onchain description: Manage barkd's on-chain bitcoin wallet. - name: wallet description: Manage Ark balances and VTXOs, send payments via Ark, LN, and on-chain. - name: bitcoin description: Query bitcoin network data. - name: notifications description: Receive real-time notifications from barkd. paths: /api/v1/exits/progress: post: tags: - exits summary: Progress exits description: >- Triggers all in-progress exits to advance by one step.
