Practical patterns for common agent scenarios

Spending Cap on a Shopping Agent

Issue a passport with a $100/day spend limit. The enforcement layer blocks any purchase that would exceed the cap and produces a signed attestation for every decision.

Gate-Protected API

Put a gate in front of your API. Credentialed agents get full access, anonymous agents get read-only with rate limits, and invalid passports are denied outright.

Human-in-the-Loop Approvals

Configure an approval threshold so any action over $200 pauses the agent and sends you a text. Reply YES or NO from your phone.

Domain-Restricted Agent

Lock an agent to only call specific domains — your internal tools and nothing else. Every blocked request is logged with a signed attestation.

Agent-to-Agent Commerce

Agents discover services, compare signed pricing catalogs, and transact with locked terms. Every call produces a metered receipt for settlement.

Multi-Level Security Profiles

Configure gates with L1 (basic), L2 (trusted issuers), or L3 (strict + proof-of-possession) security. Higher tiers require stronger agent credentials.
