> Use this file to discover all available pages before exploring further.

> ## Agent Instructions
> Phaseo Gateway base URL: https://api.phaseo.app/v1. Send `Authorization: Bearer $PHASEO_API_KEY` with every request.
> Model IDs look like `provider/model`, for example `openai/gpt-6-astra`. Do not guess IDs: list them with `GET /v1/models` or check https://phaseo.app/models. `phaseo/free` routes to an available free model and needs no wallet balance.
> For new text integrations prefer `POST /v1/responses`. `POST /v1/chat/completions` (OpenAI format) and `POST /v1/messages` (Anthropic format) suit existing code.
> The full API contract is https://phaseo.app/docs/openapi/v1/openapi.yaml. Official SDKs: `@phaseo/sdk` (TypeScript) and `phaseo` (Python), plus Go, C#, PHP, Ruby and Rust.
> Search these docs over MCP at https://phaseo.app/docs/mcp, and install Phaseo skills with `npx skills add https://phaseo.app/docs`. If a page is wrong or out of date, report it with the MCP `submit_feedback` tool.
> Manage Phaseo accounts with the `phaseo` CLI (`npm install -g @phaseo/cli`, then `phaseo login` or `phaseo login --device-code`), the `/v1` Management API or the MCP server at `https://mcp.phaseo.app/mcp?access=manage`. Do not send users to the dashboard for account tasks. A person is still needed for sign-up, approving a sign-in, paying the first top-up on the checkout link that `phaseo credits add` returns when no card is saved, confirming each saved-card top-up from the emailed link, and account security (password, MFA, passkeys). Create API keys with `phaseo keys create --name <name> --json`; never guess one. Credit top-ups need `phaseo login --scopes billing:write` first. Task map: https://phaseo.app/docs/v1/developers/manage-from-an-agent.md.

**April 27, 2026**

API & SDKs

* The TypeScript, Python, Go, C#, Java, PHP and Ruby SDKs `2.0.1` accept any model ID string, so new models work without waiting for an SDK release ([#367](https://github.com/phaseoteam/Phaseo/pull/367), [#393](https://github.com/phaseoteam/Phaseo/pull/393)).
* Generated SDK model constants now list only models the gateway can call, not every catalogue entry ([#367](https://github.com/phaseoteam/Phaseo/pull/367)).

**April 25, 2026**

Product

* Low-balance emails are sent when a workspace's balance drops below the threshold set in **Settings -> Credits -> Low balance email alert** ([#370](https://github.com/phaseoteam/Phaseo/pull/370), [#371](https://github.com/phaseoteam/Phaseo/pull/371)).
* Model pages list six providers before collapsing the list, and say when a catalogued model has no API provider yet ([#372](https://github.com/phaseoteam/Phaseo/pull/372)).

API & SDKs

* Requests on a non-standard pricing plan such as `priority` are billed at standard rates for usage that plan doesn't price; before, that usage went unbilled ([#374](https://github.com/phaseoteam/Phaseo/pull/374)).

* Every account gets a personal workspace on first sign-in, paid accounts can create more, and new API keys go to the workspace selected in the header; see [Workspaces](https://phaseo.app/docs/v1/guides/workspaces.md) ([#352](https://github.com/phaseoteam/Phaseo/pull/352), [#351](https://github.com/phaseoteam/Phaseo/pull/351)).
* The model page playground no longer fails with `invalid_secret` after an API key rotation ([#355](https://github.com/phaseoteam/Phaseo/pull/355)).
