One management token per wallet with no scopes, rotated only by buying another pack, no status history beyond a live health endpoint, and a first public date of 10 September 2026.\n\n**Amazon EventBridge.** IAM policies scope a credential to single actions and buses, and an SLA commits 99.99 per cent monthly uptime per Region. 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## Before you call either\n\n### 402cron\n\n1. Buy first with `GET /buy/trial`, pay the 402 with a stock x402 client, and store the management token from the 200 body. It's shown once; losing it costs another purchase with `?rotate=1`.\n2. Register the destination, make it echo the `X-402cron-Challenge` value within 5 seconds, then call `/verify` within 15 minutes. A fixed-response catch URL can't pass.\n3. Branch on the `error` code and the HTTP status, never on `message`. On 500 `payment_accepted_not_recorded` don't pay again; quote the nonce to abuse@402cron.com.\n4. Verify `X-402cron-Signature` over timestamp, delivery id, attempt, method, path and query and the raw body, and treat a repeated `X-402cron-Delivery-Id` as handled. Delivery is at least once.\n5. Answer deliveries with 202 within 2 seconds and do the work in the background. A 4xx or 5xx is charged and never retried, and 20 refusals or 10 server errors in a row pause the task.\n6. Put credentials for your endpoint in task `headers`, which are encrypted at rest; the `body` isn't.\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## Questions\n\n### Which is better for AI agents, 402cron or Amazon EventBridge?\n\nAmazon EventBridge scores 75.1 (BB) on agent readiness against 402cron's 63.5 (B), and leads in 5 of 7 scored categories. 402cron leads on payments \u0026 pricing.\n\n### Do 402cron and Amazon EventBridge need an API key?\n\nBoth take an API key or an OAuth sign-in. An agent can also pay 402cron per call over x402, with no account.\n\n### Can an agent call 402cron and Amazon EventBridge without installing anything?\n\nYes. 402cron has a hosted endpoint at https://402cron.com and Amazon EventBridge at https://events.us-east-1.amazonaws.com.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/402cron-vs-amazon-eventbridge.json, and with the fewest tokens: https://www.anchorterminal.com/compare/402cron-vs-amazon-eventbridge.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"402cron\", \"b\": \"amazon-eventbridge\"}`.
