Agent Enhancer Utilities

Guard x402 retries against changed terms

Compare supplied requirements, match facilitator capability documents, and bind a quote fingerprint without signing, settling, or transferring funds.

Outcome

Agents can stop a retry when commercial or resource terms drift and distinguish document compatibility from live facilitator behavior.

Use only the needed primitive

x402-requirement-drift-diff

Report exactly which normalized requirement fields changed.

Agent workflow

  1. Remove private keys, signatures, credentials, and customer data.
  2. Normalize and compare the first and current requirements.
  3. Stop for explicit review if amount, receiver, network, asset, or resource changes.
  4. Use a short-lived fingerprint guard only for the same retry workflow.

Connect an agent

Connect the agent to the public Streamable HTTP MCP endpoint, search with the concrete job, and describe only the selected tool before invoking it.
