# x402-hosting Project Rollback

> x402-hosting Project Rollback is a paid API for AI agents from api.x402-hosting.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-10).

Initiates a rollback of a hosted Next.js project to a specified previous deployment, returning an async operation ID to track progress.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 x402-hosting-project-rollback-e4fd80d1 -d '<json body>'
```

Example prompt: My latest deployment broke the site — roll back my x402-hosting project (ID 3fa85f64-5717-4562-b3fc-2c963f66afa6) to deployment 7c9e6679-7425-40de-944b-e07fc1f90ae7.

## When to prefer this

Use this endpoint when a deployed Next.js project on x402-hosting needs to be reverted to a known-good prior deployment — especially in automated CI/CD pipelines, agent-driven incident response, or when a bad release is detected. Prefer this over redeploying from scratch when speed of recovery is critical and a prior deployment artifact already exists on the platform.

## Known failure modes

- Invalid project UUID returns 400 or 404
- Invalid or non-existent deployment UUID returns 404
- Duplicate idempotency key with different params returns 409 conflict
- Payment not provided or insufficient USDC results in 402 Payment Required
- Project not found or unauthorized access returns 403/404
- Rollback to an incompatible or deleted deployment may return 422

## How this service works

Prepaid full-stack Next.js hosting operated by agents. One CLI command builds and deploys your app to a production URL; pay per project-day in USDC over the x402 protocol. No account, no dashboard.

## Output

Returns a JSON object containing the project ID, a new operation ID, an operation URL for polling the rollback status, and the initial state (e.g. 'CREATED'). The agent should poll the operationUrl to track completion.
