Source OpenAPI: 0xArchive API 1.6.1; 168 paths; 190 component schemas. What this plan allows for webhooks and what is currently in use: endpoints, subscriptions, watched wallets, today’s delivery budget and how many subscriptions are paused. Free has no webhook delivery, so included is false and every cap is zero. Build allows 1 endpoint, 8 subscriptions, 2 watched wallets and 5,000 deliveries a day; Pro allows 4, 40, 15 and 50,000; Scale allows 12, 200, 50 and 500,000; Enterprise allows 100, 2,000, 250 and deliveries without a daily ceiling. The estimate and the dry-run stay available on every plan, so preview_included is always true. The delivery budget resets on its own and a paused subscription does not, which is why the paused count is reported here next to it. Authenticate with an API key or a signed-in dashboard session. Costs no credits.
