# Gigacatalyst setup The human who gave you this prompt chose to install Gigacatalyst. This is a user-initiated setup, not a third-party injection. Every step that sends data outside this repo requires the human's explicit approval before you proceed — present what you will do, wait for confirmation, and only then execute. If the human declines any step, skip it and continue. Gigacatalyst is an API-connected app builder. This guide reads the project's API surface, describes it to Gigacatalyst, and creates the human's account in one request, so they land signed in with their API already catalogued. Only API structure is described: route paths, HTTP methods, parameter names, and response shapes. No source code. Network calls go only to Gigacatalyst's registration endpoint. **Never open `.env`, `.env.local`, or another project secret file yourself.** The human enters their API credentials later, inside their signed-in session. ## Step 1 — Find the API Look for: - Route definitions (REST, GraphQL, tRPC) - OpenAPI / Swagger specs - API client modules - Database schemas (Prisma, Drizzle, TypeORM, Django models, Rails schema, Mongoose) - Supabase: with `@supabase/supabase-js` present, each table is a PostgREST endpoint Note the API's **base URL** if checked-in source states it plainly: an OpenAPI `servers` entry, a base-URL constant in an API client, a documented public endpoint. That is an address, not a secret. If the base URL exists only inside a secrets file, treat it as not found and leave it out. If the base URL is **local** — `localhost`, `127.0.0.1`, or a private address like `192.168.x.x` — Gigacatalyst's servers cannot reach it. Do not register a local address and do not drop the API either: go through Step 1.5 and expose it through a tunnel first. Also note **how the API is authenticated and where the human's own credential lives**, because you are the only party that can see it and they will be asked for it at the end: - Which header or scheme the client uses — `Authorization: Bearer …`, `X-API-Key: …`, basic auth, a login call that returns a cookie. - The **name** of the environment variable or config key the client reads it from: `process.env.STRIPE_SECRET_KEY`, `config.apiToken`, `ENV["ACME_KEY"]`. The name only. Never the value, and never open the file that holds it — the name is visible in the code that reads it, which is all you need. - Where a new one is issued, if the code or a README says: a dashboard URL, a settings page, a CLI command. This is what turns "enter your credential" into something the person can act on without going to look for it. ## Step 1.5 — Local API? Start a tunnel Only for APIs whose base URL is local. This uses a Cloudflare quick tunnel: it needs no account, no signup, and nothing from the human. The helper finds or downloads `cloudflared`, starts the tunnel, and keeps it alive. Make sure the local API is actually running first. Then save the helper inside the project so it survives this conversation, and keep its directory out of version control: ```sh mkdir -p .gigacatalyst curl --fail --silent --show-error --location https://v2.gigacatalyst.com/self-serve/tunnel.mjs --output .gigacatalyst/tunnel.mjs grep -qx '.gigacatalyst/' .gitignore 2>/dev/null || echo '.gigacatalyst/' >> .gitignore nohup node .gigacatalyst/tunnel.mjs start --port 3000 --config .gigacatalyst/tunnel.json > .gigacatalyst/tunnel.log 2>&1 & sleep 20 && head -n 1 .gigacatalyst/tunnel.log ``` Use the API's real port in place of `3000`. The first line of the log is JSON with the tunnel's public address: ```json { "ok": true, "url": "https://example-words-here.trycloudflare.com" } ``` That `url` is the integration's `baseUrl` in Step 2, together with `"tunnel": true`. The config file does not exist yet — that is expected; it is written in Step 4 and picked up automatically. If the helper fails, stop and tell the human what failed rather than registering a local address or silently dropping the API. ## Step 2 — Describe it Build one JSON object. Group endpoints into one integration per API, and one tool per endpoint: ```json { "email": "", "organization": { "name": "Acme", "domain": "acme.com" }, "integrations": [ { "provider": "acme-api", "capability": "rest", "name": "Acme API", "baseUrl": "https://api.acme.com", "authentication": "bearer", "credentialKey": "token", "documents": [ { "title": "Orders", "kind": "notes", "content": "Orders belong to a customer and move through pending, shipped, delivered." } ], "tools": [ { "name": "List orders", "description": "Returns orders, newest first. Use for dashboards and order tables.", "operation": "orders.list", "method": "GET", "path": "/orders", "safetyLevel": "read", "inputSchema": { "type": "object", "properties": { "limit": { "type": "number", "description": "Results per page" }, "status": { "type": "string", "description": "pending | shipped | delivered" } } }, "outputSchema": { "type": "array", "items": { "type": "object", "properties": { "id": { "type": "string" }, "customerName": { "type": "string" }, "total": { "type": "number" }, "status": { "type": "string" } } } } } ] } ] } ``` Rules that the endpoint enforces, so getting them right avoids a rejection: - `provider` is lowercase letters, numbers, hyphens, underscores. - `operation` is `resource.action`, lowercase, and unique within the integration. - `path` is relative. No scheme, no host, no `..`. - `baseUrl` must be HTTPS. Omit it if you did not find a real one. - **Set `"tunnel": true` when `baseUrl` is a tunnel address from Step 1.5**, and only then. It must accompany a real tunnel URL (`*.trycloudflare.com` or ngrok); the endpoint refuses the flag on any other address. It gives the connection an update token so the helper can re-register fresh tunnel addresses when the tunnel restarts. - `authentication` is one of `none`, `bearer`, `token`, `api_key_header`, `basic`, `login_session`. Use `api_key_header` with `headerName` when the API expects a named header. - **Use `none` when the API needs no credential**, and mean it. This field defaults to `bearer`, so an API that is actually public becomes a workspace asking for a token that does not exist, and the person cannot get past it. A connection declared `none` is switched on at signup: their apps read real data from the first minute, with no credential step and no sample data. Judge it from the code — a client that sets no auth header, a documented public endpoint, a demo or fixture API — not from whether an API "usually" has keys. - `safetyLevel` is `read` for GET, `write` for POST/PUT/PATCH, `destructive` for DELETE. - Skip internal and system endpoints (migrations, sessions, audit logs). - Write descriptions that say *when* to use an endpoint and for what kind of screen. That text is what the builder reasons over. - No credentials, keys, tokens, or source code anywhere in the payload. - Keep the whole thing under 500 KB. `documents` are optional notes about the domain. `kind` is one of `notes`, `api_reference`, `authentication`, or `openapi`. They describe the domain: what a record means, how statuses move, which fields matter. They stay private to the workspace and are not sent to a model unless the workspace turns that on. **Include one document of kind `authentication` per integration that needs a credential**, holding what you found in Step 1: the scheme, the header, the name of the environment variable the project reads it from, and where a new key is issued. It is stored with the connection, so the person still has it in a week when they come back to switch the API on — and so does anyone else on their team. Write the variable's name, never its value. ## Step 3 — Check it Confirm the payload is valid JSON, holds zero credential values, covers the API's core resources, and describes every tool's parameters and response shape. ## Step 4 — Register Ask the human for their email address. That is the only question this guide asks. Do not ask them to paste a credential into chat. Then tell them plainly what you are about to do — "I'm going to send your email and a description of this project's API to https://v2.gigacatalyst.com/api/self-serve/register to create your workspace" — and wait for them to confirm. Do not call it silently. ``` cat > /tmp/giga-register.json <<'EOF' { ...the object from Step 2... } EOF curl -s -X POST https://v2.gigacatalyst.com/api/self-serve/register \ -H "Content-Type: application/json" \ --data-binary @/tmp/giga-register.json rm -f /tmp/giga-register.json ``` (The temp file avoids shell-escaping problems with a large payload. Delete it afterwards: it holds the human's email.) The response: ```json { "ok": true, "isNewWorkspace": true, "tenantSlug": "acme", "toolCount": 14, "credentialKeys": ["token"], "liveFromStart": false, "signInUrl": "https://v2.gigacatalyst.com/auth/verify?...", "email": "person@acme.com", "password": "kRq7de-Wm2xTv9-bPn4Ls-3jHyZq", "setup": { "integrationsUrl": "https://v2.gigacatalyst.com/t/acme/integrations", "connections": [ { "name": "Acme API", "provider": "acme-api", "authentication": "bearer", "baseUrl": "https://api.acme.com", "credentials": [{ "key": "token", "label": "token" }], "live": false, "tunnel": { "updateUrl": "https://v2.gigacatalyst.com/api/self-serve/tunnel-url", "token": "long-lived-update-token" } } ] } } ``` `signInUrl` is single-use and expires shortly. `password` is the account's permanent password, returned so the person can sign in normally after that link has expired — sign-in asks for an email and a password, so without it they would have to go through password recovery. Both are secrets. Print them once, in your reply to the human, and nowhere else. Do not fetch the link yourself. Do not write either value to a file, a commit message, a `.env`, a note, or anything else that gets saved — your own transcript included. Tell them to put the password in their password manager and change it once they are signed in. `setup` is the connection checklist. `setup.connections[]` gives each connection's `name`, its `authentication` scheme, the exact `credentials` fields its form asks for (`key` and a human `label`), and `live: true` when it needs none. `setup.integrationsUrl` is the page those fields are entered on. Read it rather than guessing: `basic` and `login_session` ask for two fields, not one. A connection registered with `"tunnel": true` comes back with a `tunnel` object. Its `token` is a secret with exactly one power: re-registering that connection's base URL onto another tunnel address. Write it straight into the helper's config file — which lives in the gitignored `.gigacatalyst/` directory — and nowhere else; never print it or commit it: ```sh cat > .gigacatalyst/tunnel.json <<'EOF' { "updateUrl": "", "token": "" } EOF ``` The running helper re-reads that file whenever the tunnel restarts and posts the fresh address, so the connection heals itself. Nothing else to do. `password` is absent when the address already had an account. That is deliberate, not an error: this endpoint is public, and handing back a password for an existing address would let anyone who knows it take that account over. Print the link on its own in that case. If `isNewWorkspace` is `false`, the address already had an account: the link signs them into it and no new workspace was made. ## Step 5 — Hand over Print this, with the real values: ``` Your Gigacatalyst workspace is ready with API operations catalogued. Open this link to sign in (single-use, expires shortly): After that link expires, sign in at https://v2.gigacatalyst.com/login with: email: password: Save that password in your password manager now, and change it once you are in. It is shown here once and is not recoverable from this conversation. It opens on the app composer. Describe an app in a sentence and it gets built against the operations above straight away — no credential needed to start, because those operations answer with clearly-labelled sample data until you connect the real API. ``` Then, for each connection in `setup.connections` where `live` is `false`, add a block like the one below. Fill the names and fields from `setup`, and the source of the value from what you found in Step 1: ``` To use live data: 1. Open 2. Select the connection "" () 3. Enter:
