− - [MCP server](https://mcp.angle.app.infxl.com/mcp): Streamable HTTP, POST only. Send the API key as `Authorization: Bearer infxl_live_...` or `X-API-Key`. Tools: check_company, request_brief, get_brief, list_briefs, get_account.− ## OAuth− - The MCP server takes an API key in a request header. Connectors that only support OAuth sign-in, such as ChatGPT's, cannot use it yet; OAuth is planned.− - Until then, tell the user they can subscribe on the website, https://angle.app.infxl.com, to receive briefs on a schedule, instead of requesting one brief at a time through the MCP server. Or connect from a client that can send a header.− - Early access: API keys and credits are issued by email from support.angle@infxl.com.− - One credit per brief, spent only when the brief is ready with at least one item. A credit costs $6.+ - [MCP server](https://mcp.angle.app.infxl.com/mcp): Streamable HTTP, POST only. Connect by OAuth sign-in, or send an API key as `Authorization: Bearer infxl_live_...` or `X-API-Key`. Tools: check_company, request_brief, get_brief, list_briefs, get_account, get_sample_brief (free, no sign-in or key needed).+ - [Sample brief](https://angle.app.infxl.com/skills/infxl-angle/sample-brief.md): what get_brief returns for a ready brief, in Markdown. A real brief from an earlier date, not current news.+ ## OAuth sign-in+ - The MCP server supports OAuth sign-in (MCP authorization, protected resource metadata at https://mcp.angle.app.infxl.com/.well-known/oauth-protected-resource/mcp). OAuth connectors such as ChatGPT's, claude.ai's and Claude Code's open the sign-in page the first time a tool needs an account.+ - The user signs in with an Infxl Angle account and approves; a new account gets 1 free brief credit. An API key can be pasted on that page instead.+ - For briefs on a schedule rather than one at a time, the user can also subscribe on the website, https://angle.app.infxl.com.+ - One credit per brief, spent only when the brief is ready with at least one item. A credit costs $6; a pack of 6 credits costs $30.+ - Buying credits: the server gives the link. `INSUFFICIENT_CREDITS` and `get_account` carry `top_up_url`; a keyless 401 carries `buy_url`, which creates an account and returns its API key once. POST it with an MPP wallet (for example the Link agent wallet), or open it in a browser to pay by card. Ask the user before spending. If no link is given, credits are bought by email at support.angle@infxl.com.+ - [Server card](https://mcp.angle.app.infxl.com/mcp/server-card): the MCP server's identity and connection details (SEP-2127), before connecting.+ - Credits expire 12 months after credits were last added to the account; adding credits extends every remaining credit.
