How this service works
Get a Discord, Slack, Telegram or ntfy alert when a wallet approves a token, a Safe changes owners or queues a transaction, or a proxy is upgraded. Base, Ethereum, Arbitrum, Optimism. Free tier, no signup.
Output
Returns a JSON object containing a new or extended lb_-prefixed API key, the plan name ('pro'), the Unix timestamp when the Pro plan expires (pro_until), and a hint for the next step (POST /api/watch with x-api-key header to configure watchers).
Example use cases
Safe multisig owner change alerts
“I manage a Safe multisig on Arbitrum and need to be notified immediately on Slack whenever an owner is added or removed or a transaction gets queued — can you get me a Ledgerbell Pro key to set that up?”
Token approval monitoring for a DeFi wallet
“I want to watch my Ethereum wallet and get a Telegram message any time it approves a token spend — can you purchase a 7-day Ledgerbell Pro key for me so I can start configuring those alerts?”
Proxy contract upgrade surveillance
“We have a proxy contract on Base and need our team notified on Discord the moment it's upgraded — please get a Ledgerbell Pro API key so we can wire up that monitoring.”
Technical details
Endpoint
GEThttps://ledgerbell.quietworklabs.workers.dev/x402/pro-7d?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to provision or renew a Ledgerbell Pro API key to monitor EVM wallets, Safe multisigs, or proxy contracts for onchain events (token approvals, owner changes, queued transactions, upgrades) with push alerts to Discord, Slack, Telegram, or ntfy on Base, Ethereum, Arbitrum, or Optimism. Prefer this over generic blockchain indexers when you specifically need real-time notification delivery to messaging platforms without running your own infrastructure.

- Payment not received or insufficient USDC — key not issued
- Invalid or expired existing key passed as query param — may fail to extend
