Before executing a destructive or hard-to-reverse operation on platforms like Gmail, Shopify, Stripe, and 17+ others, an agent can query this service to learn whether the action is reversible, what the recovery window is, and what safer alternatives exist.\n\nThe primary endpoint, POST /v1/check, accepts a platform identifier, resource type, action name, and optional batch scope/count. It returns a reversibility level, risk score, recovery mechanism, recovery window, safer alternatives with recommendations, and batch safety warnings when applicable. A lighter POST /v1/lookup endpoint provides a quick pre-flight check with just the reversibility level, recovery mechanism, and a single safer alternative. Two additional GET endpoints list supported platforms and their tracked actions, both free of charge.\n\nPricing follows the x402 protocol: $0.002 per request (USDC on Base) for the /v1/check and /v1/lookup endpoints, with a free tier of 10 queries per day per IP requiring no signup. The service advertises sub-50ms response times as a pure data lookup. Note that during probing the endpoint returned HTTP 400 rather than the expected 402 payment challenge, so liveness via x402 could not be fully confirmed; however, the landing page, OpenAPI spec, and discovery files are all served correctly.","tags":[],"capabilities":["reversibility-check","risk-scoring","recovery-window-lookup","safer-alternative-suggestion","batch-safety-warning","multi-platform-support","x402-payment","usdc-on-base","sub-50ms-latency","agent-discovery"],"categories":["safety","agent-tooling"],"synonyms":["undo check API","action reversibility","destructive action guard","agent safety check","rollback intelligence","platform action undo","irreversible action detector","AI agent guardrail"],"warnings":["x402 probe returned HTTP 400 on POST, not the expected 402 payment challenge — endpoint liveness via x402 not fully confirmed","No /docs, /api, /pricing, or /README pages exist (all return 404)","Example response is inferred from the OpenAPI schema, not captured from a live call"],"endpointUrl":"https://undo.agentutil.net/v1/check","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","openapi":"https://undo.agentutil.net/openapi.json","version":"2","docs_url":"https://undo.agentutil.net/.well-known/agent-service.json","free_tier":"10 queries/day without payment","description":"Before deleting or modifying data on Gmail, Shopify, Stripe, and 17 other platforms -- check if the action can be undone, get recovery windows, and find safer alternatives"},"payTo":"0x1357bef96ec515d250137d7eb712f0395eb5142d","amount":"2000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300}]},"qualityScore":"0.620","qualityRationale":"Full OpenAPI 3.1 schema with request/response definitions and clear pricing metadata.
