# FellowMakers.app > One founder asked to connect. Hundreds answered. A landscape of who they are and what they are building, drawn only from what they wrote themselves. FellowMakers.app has a public site, an HTTP API described by OpenAPI, an OAuth 2.1 authorization server and a Model Context Protocol (MCP) endpoint. Every public page has a Markdown twin: append `.md` to its path, or send `Accept: text/markdown`. ## When to use FellowMakers.app Use it to: - Look up who wrote the sentence that went round X in September 2026 (one founder asked to connect; hundreds answered or posted their own) and what they said they build, through the landscape API under /api/landscape, which needs no token. - Read the map: people by country and the hour they posted, and who shares an audience, a problem or a skill with whom, at /api/landscape/map and /api/landscape/map/edges. - Find people by sector, place, how much they said, or a search word, and follow them to their projects and the waves they belong to. - Read the waves: groups of people who never met and are building the same thing, written up by an editor. - Read any page as Markdown by appending .md to its path, instead of scraping HTML. Not for: - Anything about a person they did not write themselves in public: there are no follower counts, likes, rankings or inferred locations. - Changing the map through the API: a card is changed only by its owner, signed in with the X account that wrote the post, or by the publisher on request through the contact page. ## How to call it - MCP endpoint: https://fellowmakers.app/mcp (Streamable HTTP). Server card: https://fellowmakers.app/mcp/server-card. Read-only project analysis tools; require read scope and exclude people, builders and personal evidence: - `get_project`: Get a project by slug, its captured website information and related projects for analysis. Does not return builders, personal profiles or personal evidence. Read-only. - `search_projects`: Search products by meaning, problem or audience, with source excerpts. Optional sector and limit. Queries are recorded. Use get_project for details. Read-only. - `search_waves`: Search shared ideas across projects. Returns wave summaries. Optional group and limit. Queries are recorded. Read-only. - Landscape data: JSON, no token. https://fellowmakers.app/api/landscape (the thread, counts, waves, homepages); https://fellowmakers.app/api/landscape/people with `sector`, `place`, `said` (named, described, domain, identity) and `q`; https://fellowmakers.app/api/landscape/people/:id; https://fellowmakers.app/api/landscape/projects; https://fellowmakers.app/api/landscape/projects/:slug; https://fellowmakers.app/api/landscape/waves; https://fellowmakers.app/api/landscape/waves/:slug. - HTTP API: OpenAPI 3.1 at https://fellowmakers.app/openapi.json, index at https://fellowmakers.app/api. No token is needed for https://fellowmakers.app/api/health. - Authorization: OAuth 2.1 authorization code with PKCE. Metadata: https://fellowmakers.app/.well-known/oauth-authorization-server. Register a client at https://fellowmakers.app/api/oauth/register (open, immediate, no sales contact) or present a Client ID Metadata Document. Scopes: openid, profile, email, read, write. - Sandbox: https://landscape-stage.krasnoperov.me runs the same code against its own data. Register clients and test there first. - Versioning: by date, current 2026-09-10; send `API-Version: 2026-09-10` to pin, omit it for the current version. Every /api response names the version that answered. - Rate limits: 1200 requests per minute per address for the API, tighter on the OAuth endpoints; every /api response carries RateLimit-Policy, a refusal is 429 with Retry-After. - Errors: JSON with `error` and, when there is more to say, `error_description`. Unknown paths answer 404 with a Markdown body that says where to look next. ## Documentation - [FellowMakers.app](https://fellowmakers.app/index.md): One founder asked to connect. Hundreds answered.
