First Paid Invocation

The shortest proof that Synapse is routing, charging, and producing receipts.

Minimal path

  1. Get a wallet challenge from GET /api/v1/auth/challenge.
  2. Verify the signature with POST /api/v1/auth/verify.
  3. Confirm a positive balance with GET /api/v1/balance.
  4. Issue a credential with POST /api/v1/credentials/agent/issue.
  5. Discover a service with GET /api/v1/services/discover.
  6. Invoke with POST /api/v1/agent/invoke using the live price observed during discovery.

Success = charged balance + provider receivable + invocation receipt with a stable invocation ID.

For API Providers

Publish APIs as paid agent-callable services and earn USDC per invocation.

MCP / Agent Tooling

Use Synapse from Claude Desktop, Cursor, Devin, and MCP-compatible agent runtimes.
