Use GitDealFlow A2A with Zapier
Visual automation across 7,000+ apps. Non-engineers who want VC signals piped into their existing stack (Notion, Airtable, Gmail, Slack).
Crunchbase API: $20K/yr. GitDealFlow A2A: free, no signup.
Zapier's Webhooks app POSTs JSON-RPC to our A2A endpoint with no code. Schedule trigger → Webhooks POST → Formatter (parse JSON) → Slack/Notion/Gmail. The path is uglier than n8n but Zapier reaches a much bigger surface of downstream tools, Notion databases, Google Sheets, HubSpot CRM.
Endpoint facts for Zapier users
Whatever wiring you choose, the target is the same single endpoint. These are the fixed facts; nothing on this page changes them:
| Protocol | A2A JSON-RPC 2.0 (protocolVersion 0.3.0) |
| Endpoint URL | https://signals.gitdealflow.com/api/a2a |
| Skills exposed | 5, mirrored 1:1 with the MCP server tools (trending, sector, lookup, summary, methodology) |
| Auth | None; free in perpetuity, read-only |
| Freshness | Recomputed weekly; responses carry the data-as-of date |
| Best Zapier path | Zapier has no native MCP client yet, so the custom-tool path below (a thin JSON-RPC call) is the way in. |
Webhooks by Zapier (POST)
// Zap config:
// 1. Trigger: Schedule by Zapier (every Monday 9am)
// 2. Action: Webhooks by Zapier → Custom Request
// Method: POST
// URL: https://signals.gitdealflow.com/api/a2a
// Data Pass-Through?: No
// Data: (raw JSON)
// {"jsonrpc":"2.0","id":1,"method":"message/send","params":{"message":{"role":"user","parts":[{"kind":"data","data":{"skill":"get_trending_startups"}}]}}}
// Headers: Content-Type | application/json
//
// 3. Action: Formatter → Utilities → Pick from List
// Input: {{step2.result.artifacts.0.parts.0.data.startups}}
//
// 4. Action: Slack → Send Channel Message (or Notion → Create Database Item, etc.)What you can ask
- Monday 9am Slack digest of top 5 trending.
- New row in Airtable 'watchlist' → A2A signal lookup → fill 'last_signal' column.
- Daily Notion page in your investing journal with the breakout of the day.
- Email me when a tracked sector has 5+ breakouts this week.
Gotchas
- Zapier's free plan caps Webhook calls and adds 15-min trigger delay, fine for digest use cases, painful for real-time. Upgrade to Starter ($30/mo) if you need <5min latency.
- Zapier truncates large JSON responses in its UI preview; the full payload is still passed downstream, trust the field paths, not what the visual builder shows.
When to pick which path
Because Zapier currently lacks a native MCP client, your two options are the custom tool below (a thin JSON-RPC wrapper you register once) or switching the session to an MCP-capable host when you need the richer tool surface. For scheduled jobs and pipelines, the raw endpoint is usually the sturdier dependency: no client versioning to track.
4example prompts are listed under "What you can ask" below, and the gotchas section covers the 2 known failure modes Zapier users hit with this endpoint. If a prompt fails, check the gotchas first: most misses are shape mismatches, not endpoint outages.
