Reaching it + +| | | +|---|---| +| Base URL | `http://phase.invalid` (plain `http`; the proxy answers before any upstream) | +| Transport | Any HTTP client whose proxy settings point at the Phase proxy. In transparent mode and under `phase ai run/exec`, `HTTP_PROXY`/`HTTPS_PROXY` already carry the credentials, so `curl http://phase.invalid/v1/status` just works. | +| Authentication | `Proxy-Authorization: Basic base64("phase:")`. The capability is the per-process proxy password that only the runtime hands out; it is never a Phase token. | +| Connection selection | Username `phase.` instead of `phase` scopes the request to one Connection (used for `/v1/connections/{id}/environment` and for proxied traffic when two Connections share a host). | +| Content type | JSON in, JSON out. `Cache-Control: no-store` on every control response. | +| Query strings | Rejected (400 `invalid_control_query`) except `?wait=` on request creation/polling and `?serviceType=` on context. | +| Browser safety | A `POST` carrying `Origin`, `Referer` or a `Sec-Fetch-Site` other than `none` is refused with 403 `browser_control_mutation_rejected`. | +| Remote (relay) mode | Same routes over the relay's TLS proxy (`phase relay start`), except `GET /v1/discover`, `POST /v1/revoke` and `POST /v1/rotate`, which are local-only. `GET /v1/bootstrap` exists only on a relay. | +| Limits | Request bodies ≤ 64 KiB.

Who calls what, and when + +| Caller | Routes | When | +|---|---|---| +| The Agent, following the `phase-cli` skill | `GET /v1/capabilities`, `GET /v1/status` | When the human asks for Phase, or to find out whether Phase can manage a service. In transparent mode the per-prompt status line already names the ready Connections, so this is mostly for service discovery. | +| The Agent | `GET /v1/context?serviceType=…` | Before using a service through Phase: provider-specific instructions and limitations, rendered by Console. | +| The Agent | `POST /v1/requests`, `GET /v1/requests/{id}?wait=300`, `GET /v1/requests`, `POST /v1/requests/{id}/cancel` | No suitable Connection exists (`setup`), or the provider rejected the credential (`credential_update`). The Agent prints `approvalUrl` for the human, then long-polls. | +| `phase ai exec --connection ` (the CLI, not the Agent) | `GET /v1/connections/{id}/environment` | Builds the per-Connection process environment (decoys + scoped proxy URL) for one command. Sensitive: contains the proxy password. | +| Hook wrapper `phase ai __harness-exec` and `phase ai exec` attach | `GET /.well-known/agents` (manifest) | Right before running a wrapped command, to fetch the exact process environment of the live runtime. Sensitive; the skill forbids the Agent from fetching it. | +| Claude Code hooks in transparent mode | nothing | SessionStart and heartbeat read local files only; the shell sources `~/.phase/ai/env.sh`. | +| `phase ai disable`, daemon replacement | `POST /v1/revoke` | Authenticated local shutdown: Console revokes the session, the proxy stops. | +| Nothing today | `POST /v1/rotate`, `POST /v1/refresh`, `GET /v1/discover` | Lifecycle/diagnostic routes kept for tooling and tests. The skill tells the Agent never to call refresh. | + +## 3. Error envelope + +Every control error (and every non-AWS proxied failure) uses the same body and +also sets `X-Phase-Error-Code`.
