Get a key

Enter your email, click the verification link we send, and your key is minted. No credit card.

No card. A key is required for 9 listed tools; actual use still depends on provider and compliance availability. The free tier includes up to 100 write operations a day.

Prefer the terminal? The same request, by hand:

POST /keys/requestlive
curl -X POST https://hatchloop.dev/keys/request \
  -H "Content-Type: application/json" \
  -d '{"email": "you@example.com"}'

# Response
{
  "status": "verification_sent",
  "detail": "Check your inbox for a verification link.
             It expires in 1 hour."
}

Click the link in the email and your key appears on the confirmation page (and lands in your inbox). Free keys allow 100 gated operations per day. Trouble? Email hello@hatchloop.dev.

Auth headers

Pass your key as the X-Agent-Identity header. All operations that have a cost require a valid key.

# Direct HTTP
POST https://hatchloop.dev/mcp/agent-broker
Content-Type: application/json
X-Agent-Identity: YOUR_KEY_HERE

# In MCP config
{
  "mcpServers": {
    "agentbroker": {
      "url": "https://hatchloop.dev/mcp/agent-broker",
      "headers": {
        "X-Agent-Identity": "YOUR_KEY_HERE"
      }
    }
  }
}

FAQ

Is the free key really free forever?
Yes. An email-verified free key costs nothing. Credit purchases are not enabled; there is currently no paid upgrade to extend the free allowance. See /pricing/ for availability.
What is the rate limit on the free tier?
A free key allows 100 gated (write) operations per day, plus 500 premium data calls/day. Read tools like find_business and verify_business are free without any key. General service limits apply. Credit purchases are not enabled; use check_quota for your remaining allowance.
Which MCP clients does AgentBroker work with?
Any MCP-compatible client: Claude Desktop, Cursor, Claude Code, or any custom agent that speaks the MCP JSON-RPC spec. Add the endpoint URL and key header to your config.
Can agents pay in crypto?
Not yet. Crypto pay-per-call (x402, USDC on Base) is not enabled, so there is no payment address and nothing to attach to a call. Credit purchases are not enabled either. The free tier needs no payment.
