For developers

No signup required to start. Verify a real receipt, point an agent at the governed MCP surface, and see cryptographic proof come back in the response — in about five minutes.

Zero to verified

The receipt verifier and a read-only, rate-limited MCP demo key are public — so you can evaluate everything below without an account or a credit card. The examples use only public endpoints; nothing here touches production systems.

Step 1

Every autonomous action returns a receipt ID. Verify one against the public ledger — no auth.

# Verify any ProofLink receipt against the public ledger
curl -s https://verify.itechsmart.dev/api/receipt/<RECEIPT_ID>

# Response includes the sealed action, hash chain status,
# and OpenTimestamps/Bitcoin anchor — verifiable independently.
Step 2

Point any MCP client (Claude, ChatGPT, LangGraph, CrewAI) at the governed surface with the public read-only key.

{
  "mcpServers": {
    "itechsmart": {
      "url": "https://mcp.itechsmart.dev/sse",
      "headers": {
        "Authorization": "Bearer MCP-SECRETEYE-123456"
      }
    }
  }
}
Step 3

List the governed tools and fetch the A2A agent card — every side-effecting call returns a receipt.

# List available MCP tools
curl -s https://mcp.itechsmart.dev/mcp/tools

# Fetch the A2A agent card
curl -s https://mcp.itechsmart.dev/.well-known/agent.json

# Public platform health (no auth)
curl -s https://mcp.itechsmart.dev/health
What to build next

01

Receipt every action

Have your agents seal a ProofLink receipt for each meaningful action, then surface the verify URL to your users.

02

Govern side-effecting calls

Route high-impact tool calls through the policy-gated surface so they're approved, blocked, or queued — and receipted.

03

Automate verification

Add a CI or runtime check that verifies receipts against the public ledger as part of your audit trail.

04

Import the Postman collection

Grab the collection linked above for ready-to-run requests against the public endpoints.

Straight answers

No. The receipt verifier is public, and the MCP surface has a read-only, rate-limited demo key (MCP-SECRETEYE-123456) so you can evaluate everything before signing up.

Verify a receipt, connect an agent, and ship AI actions you can prove. Dive into the MCP docs next.
