Quick pre-flight lookup: can this platform action be undone? Returns reversibility level, recovery window, and safer alternatives.
What it does
AgentUtil Undo `/v1/lookup` is a lightweight reversibility-intelligence endpoint designed for autonomous AI agents. Before an agent commits a potentially destructive action on platforms like Gmail, Shopify, Stripe, and others, it can POST the platform name, resource type, and intended action to this endpoint. The response includes the reversibility level, recovery mechanism, and a safer alternative if one exists. It serves as a fast pre-flight check (advertised <50ms) so agents can make informed decisions before modifying or deleting data.
The `/v1/lookup` endpoint is a simplified version of the companion `/v1/check` endpoint — it omits batch-warning logic and returns a single safer alternative rather than a list. Both endpoints accept the same core parameters (platform, resource, action). The service covers 17+ platforms and is a pure data lookup with no side effects.
Pricing: There is a free tier of 10 queries per day per IP with no signup required. Beyond that, paid access uses the x402 protocol, settling in USDC on Base at $0.002 per request. The `/v1/platforms` and `/v1/platforms/:id` endpoints are free and can be used to discover supported platforms and their tracked actions.
Capabilities
Use cases
- —An AI agent checks whether deleting a Gmail email is reversible before executing the action
- —An autonomous workflow verifies that canceling a Stripe subscription can be undone and learns the recovery window
- —A batch-processing agent looks up safer alternatives before bulk-archiving Shopify products
- —An agent orchestration layer gates destructive operations behind a reversibility pre-flight check
- —A developer integrates the lookup into an agent framework to prevent irreversible mistakes
Fit
Best for
- —AI agents that perform destructive or modifying actions on third-party platforms
- —Agent orchestration frameworks that need safety guardrails
- —Developers building autonomous workflows across Gmail, Shopify, Stripe, and similar services
Not for
- —Actually undoing or rolling back actions — this is a lookup service only
- —Real-time monitoring or audit logging of actions already taken
- —Platforms not in the supported list (check /v1/platforms for coverage)

Quality
Full OpenAPI schema with request/response definitions is available, and the landing page documents pricing and endpoints clearly. However, the probe did not capture a 402 challenge (returned 400 on POST, 404 on GET), so liveness via x402 cannot be confirmed. No dedicated docs page exists, and the example response is inferred from the schema rather than captured live.
Warnings
- —Probe did not receive a 402 x402 challenge — endpoint returned 400 on POST, suggesting it may require a valid JSON body to trigger the payment challenge or may behave differently than standard x402 flow.
- —No dedicated documentation page exists (/docs, /api, /pricing all return 404).
- —Example response is inferred from the OpenAPI schema, not captured from a live call.
