The Custom Event Bus API of 24 September 2026 adds retention, replay, ordering and publish-time deduplication. Classic `PutEvents` takes no idempotency token and answers 200 for a bus that does not exist. A person must open the AWS account.\n\n**Hook0.** Hook0 Cloud sends signed webhooks from one REST call, with a public OpenAPI document, RFC 7807 errors and service tokens that can be narrowed offline to one application, an expiry or read-only actions. Six security advisories were published between August and September 2026, one rated High. Signup needs a browser check, and no uptime commitment exists below Enterprise.\n\n## Before you call either\n\n### Amazon EventBridge\n\n1. Use `aws eventsv2` and the `EventBridgeV2` SDK client for the Custom Event Bus, but write IAM actions with the `events:` prefix. A policy naming `eventsv2:` grants nothing\n2. After a Classic `PutEvents` call, check `FailedEntryCount` and each entry's `ErrorCode`, then resend failed entries yourself. A request holds up to 10 entries and under 1 MB\n3. Set `SystemMetadata.DeduplicationId` on Custom Event Bus entries when retrying a publish, and treat a `SuccessCode` of `DEDUPLICATED` as success\n4. Set `RetryPolicy` and `OnFailureConfiguration` when creating a subscriber. The defaults stop after 5 attempts or 300 seconds, and an exhausted event is dropped\n5. Store the full bus ARN. A Custom Event Bus ARN ends in a generated identifier that changes when a bus of the same name is recreated\n\n### Hook0\n\n1. Use a service token narrowed to one application and an expiry. A root service token covers the whole organisation, and an application secret can delete its application\n2. Send your own UUID as `event_id` on `POST /api/v1/event/`. A repeat returns `EventAlreadyIngested` (409), which means the first call succeeded\n3. Create the event type before sending. Unknown types fail with `EventTypeDoesNotExist`, and `labels`, `occurred_at` and `payload_content_type` are required\n4. Send `payload` as a string, with JSON serialised inside it, up to 512 KiB\n5. Set `HOOK0_API_URL` for `hook0-mcp` to the origin without `/api/v1`, and set `HOOK0_READ_ONLY=true` to hide the ten write tools\n\n## Questions\n\n### Which is better for AI agents, Amazon EventBridge or Hook0?\n\nAmazon EventBridge scores 73.7 (BB) on agent readiness against Hook0's 64.6 (B), and leads in 5 of 7 scored categories. Hook0 leads on payments \u0026 pricing and maintenance \u0026 community.\n\n### Do Amazon EventBridge and Hook0 need an API key?\n\nAmazon EventBridge takes an API key or an OAuth sign-in. Hook0 needs an API key.\n\n### Can an agent call Amazon EventBridge and Hook0 without installing anything?\n\nAmazon EventBridge has a hosted endpoint at https://events.us-east-1.amazonaws.com.
