> 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 If a page is wrong or out of date, report it with the MCP `submit_feedback` tool.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.

# February

> Phaseo product updates, SDK changes, and model releases from February 2026.

**February 27, 2026**

Product

* Email sign-in shows why an attempt failed, such as a wrong password or an unverified email, on the sign-in page instead of a generic error page ([#116](https://github.com/phaseoteam/Phaseo/pull/116)).
* Email sign-up lists the password rules (lowercase, uppercase, number and symbol) and checks them before the form is sent ([#113](https://github.com/phaseoteam/Phaseo/pull/113)).
* The models table shows prices per million units correctly and uses the full page width; before, some rows showed extremely high prices ([#113](https://github.com/phaseoteam/Phaseo/pull/113), [#116](https://github.com/phaseoteam/Phaseo/pull/116)).

API & SDKs

* Gemini 3 requests map `reasoning.effort` to the thinking levels each model supports, from `minimal` to `high` ([#113](https://github.com/phaseoteam/Phaseo/pull/113)).

**February 26, 2026**

API & SDKs

* **Breaking:** `/v1/responses/ws` is now marked experimental and rejects plain model slugs; send `openai/<model>` IDs, and use `POST /v1/responses` for production ([#112](https://github.com/phaseoteam/Phaseo/pull/112)).
