GramClaw API

Drive your Telegram outreach from scripts, AI agents, or the Telegram MCP server: search messages, manage the CRM pipeline, set custom columns, and send messages, broadcasts, and campaigns. Create a key in Settings → API Keys.

Authentication

Every request needs a workspace API key as a Bearer token. Create one in Settings → API Keys — the full key ( gc_live_…) is shown once.

Base URL

https://gramclaw.com

Every request

Authorization: Bearer gc_live_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Quick start

BASE="https://gramclaw.com"
KEY="gc_live_…"
curl -s "$BASE/api/v1/me" -H "Authorization: Bearer $KEY"

Heads up: API calls execute directly — there is no confirmation step (unlike the in-app AI). The key is the authorization; guard it like a password. Rate limit: 120 requests / minute per key, with X-RateLimit-* headers on every response. Errors return { "error": "…" } with a 4xx/5xx status.

Scopes: keys carry read (chats, messages, search, analytics), write (pipeline, columns, webhooks), and/or send (messages, broadcasts, campaigns) — choose them when creating the key. Send-type POSTs accept an Idempotency-Key header so retries never double-send.

Endpoints

Connect from Claude / Cursor (Telegram MCP)

Easiest — remote connector (a URL). In your MCP client, add a custom connector and paste your personal URL. Create a key in Settings → API Keys to get the full URL with your key. See the Telegram MCP overview for the tool list.

Remote MCP URL

https://gramclaw.com/api/mcp?key=gc_live_…

Alternative — local server (Cursor, or Claude Desktop config file):

claude_desktop_config.json

{
  "mcpServers": {
    "gramclaw": {
      "command": "npx",
      "args": ["-y", "gramclaw-mcp"],
      "env": {
        "GRAMCLAW_API_KEY": "gc_live_…",
        "GRAMCLAW_BASE_URL": "https://gramclaw.com"
      }
    }
  }
