Conversational AI design + agent platform. Builders shipping voice + chat agents for customer-facing surfaces who want VC signal lookups inside the flow.
Crunchbase API: $20K/yr. GitDealFlow A2A: free, no signup.
Voiceflow's Knowledge Base + API Step lets you wire any HTTP endpoint into a conversation flow. Add GitDealFlow as a Function or API Block so a Voiceflow-powered support agent, sales assistant, or onboarding bot can surface live engineering signals when a user asks about a competitor or trending startup. Best fit for teams already shipping branded conversational AI on web/IVR/Slack who want to enrich their bot's knowledge with live alt-data without retraining.
// Voiceflow Designer → API Block configuration
// Method: POST
// URL: https://signals.gitdealflow.com/api/a2a
// Headers: Content-Type | application/json
// Body (raw JSON):
{
"jsonrpc": "2.0",
"id": 1,
"method": "message/send",
"params": {
"message": {
"role": "user",
"parts": [
{"kind": "data", "data": {"skill": "{skill}", "args": "{args}"}}
]
}
}
}
// Variables:
// {skill} — pulled from intent slot (one of: trending, sector, startup, methodology, receipts)
// {args} — pulled from entity slot (sector slug or startup name)
//
// Capture response into {gitdealflow_response}, then route to:
// - Speak/Send Text Block: "{gitdealflow_response.artifacts[0].parts[0].data.startups[0].name} is up {...}"
// - Carousel Block: visual cards for each startup result// In Voiceflow Project Settings → Functions → New Function
// Function definition (JavaScript):
async function gitdealflow_query(args) {
const body = {
jsonrpc: "2.0", id: 1,
method: "message/send",
params: {
message: {
role: "user",
parts: [{kind: "data", data: {skill: args.skill, args: args.args || {}}}]
}
}
};
const res = await fetch("https://signals.gitdealflow.com/api/a2a", {
method: "POST",
headers: {"Content-Type": "application/json"},
body: JSON.stringify(body)
});
return await res.json();
}
// Then in your flow → Function Block → call gitdealflow_query with input mappingThe interactive playground lets you send live JSON-RPC requests against the A2A endpoint with no install, no auth. Pick a skill, hit send, see the response.
