No batching or digest step, llms.txt, error code list, SLA or sub-processor list was found, and project tokens carry no scopes.\n\n**OneSignal.** Runs push delivery itself, so there's no separate push provider to wire up. Three incidents on the API and SDK endpoints in September 2026.\n\n## Before you call either\n\n### MagicBell\n\n1. Ask the owner for a Project JWT from the dashboard's Project Auth page. The terms forbid accounts registered by automated methods\n2. Send `Idempotency-Key` with a UUID on `POST /v2/broadcasts`, and reuse it on a retry within 24 hours\n3. Stay under 500 requests a minute per IP. A 429 blocks the address for 60 seconds, so put many recipients in one broadcast\n4. Use a Project JWT for broadcasts, users, integrations and workflows, and a User JWT for one user's inbox, tokens and preferences\n5. Read delivery failures from `GET /v2/events` and the broadcast's `status`, since email, SMS and push go through providers the owner connects\n\n### OneSignal\n\n1. Use `Authorization: Key \u003ckey\u003e`, not Bearer, and put `app_id` in the body\n2. Send an `idempotency_key` UUID with every create call and reuse it on each retry\n3. On 429, wait for `Retry-After`, then back off with jitter, up to 10 attempts\n4. Stay under 10 sends per subscribed subscription in 15 minutes or the app is disabled\n5. Target people with `include_aliases.external_id` and set `target_channel`\n\n## Questions\n\n### Which is better for AI agents, MagicBell or OneSignal?\n\nOneSignal scores 69.3 (B) on agent readiness against MagicBell's 58.8 (C), and leads in 5 of 7 scored categories. MagicBell leads on reliability.\n\n### Do MagicBell and OneSignal need an API key?\n\nMagicBell needs an API key. OneSignal takes an API key or an OAuth sign-in.\n\n### Can an agent call MagicBell and OneSignal without installing anything?\n\nYes. MagicBell has a hosted endpoint at https://api.magicbell.com/v2 and OneSignal at https://api.onesignal.com.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/magicbell-vs-onesignal.json, and with the fewest tokens: https://www.anchorterminal.com/compare/magicbell-vs-onesignal.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"magicbell\", \"b\": \"onesignal\"}`.
