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 If a page is wrong or out of date, report it with the MCP `submit_feedback` tool.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

# Examples

> Choose a runnable Phaseo starter project for a browser app, backend, or CLI.

Choose a sample project to run locally and adapt. For a single API call, use the [Quickstart](https://phaseo.app/docs/v1/quickstart.md); for a specific feature, browse the [Cookbook](https://phaseo.app/docs/v1/cookbook.md).

## Runnable projects

| Build | Walkthrough | Source |
| - | - | - |
| Browser chat with a server-side API key | [Next.js chat](https://phaseo.app/docs/v1/cookbook/build-a-nextjs-web-chat-app.md) | [web-chat-nextjs](https://github.com/phaseoteam/Phaseo/tree/main/examples/web-chat-nextjs) |
| OAuth authorisation and a backend proxy | [OAuth workbench](https://phaseo.app/docs/v1/cookbook/build-an-oauth-nextjs-workbench.md) | [oauth-client-nextjs](https://github.com/phaseoteam/Phaseo/tree/main/examples/oauth-client-nextjs) |
| A minimal REST integration | [Node smoke app](https://phaseo.app/docs/v1/cookbook/build-a-node-rest-smoke-app.md) | [gateway-node-quickstart](https://github.com/phaseoteam/Phaseo/tree/main/examples/gateway-node-quickstart) |
| A Python command-line application | [Python CLI](https://phaseo.app/docs/v1/cookbook/build-a-python-gateway-cli.md) | [gateway-python-quickstart](https://github.com/phaseoteam/Phaseo/tree/main/examples/gateway-python-quickstart) |
| An application using Vercel AI SDK | [AI SDK integration](https://phaseo.app/docs/v1/guides/integrations/ai-sdk.md) | [ai-sdk-v7-quickstart](https://github.com/phaseoteam/Phaseo/tree/main/examples/ai-sdk-v7-quickstart) |

Keep credentials on the server, review the sample's environment variables, and check the selected model's pricing before running it. Examples using `:free` models do not require deposited credits.

## Language-specific requests

The [Client SDK reference](https://phaseo.app/docs/v1/sdk-reference/typescript/overview.md) contains installation and request examples by language. Use the [image generation reference](https://phaseo.app/docs/v1/api-reference/endpoint/images-generations.md) for image parameters and [Chat Completions](https://phaseo.app/docs/v1/api-reference/endpoint/chat-completions.md) for chat requests.

For a coding agent to scaffold a project, use [mini-app starter prompts](https://phaseo.app/docs/v1/cookbook/mini-app-starter-prompts.md) and review the generated code before using it with live credentials.
