How this service works
List your subscriptions. 📖 Full guide: https://inbox.withzero.xyz/llms.txt
Output
Returns a JSON object with a 'subscriptions' array; each element contains: id (string), fromWallet (wallet address), topicPattern (glob pattern for subscribed topic), trigger (either null, a scheduler-run object with taskId UUID, or a webhook object with url and optional secret), and createdAt timestamp.
Example use cases
Audit active subscriptions before cleanup
“Can you list all my current inbox subscriptions? I want to see everything I'm subscribed to right now so I can identify which ones I don't need anymore.”
Verify webhook configuration on subscriptions
“Show me all my active subscriptions and check which ones have webhooks configured versus scheduler triggers — I need to know what's actually listening for events.”
Check subscription status across wallets
“List all the topic subscriptions associated with my inbox wallet and tell me if there are any subscriptions set up that I might've forgotten about.”
Technical details
Endpoint
GEThttps://inbox.withzero.xyz/api/v1/subscriptionsWhen to prefer
Use this endpoint when an agent needs to audit its current subscriptions, verify a subscription was created, check trigger configurations (webhook vs scheduler), or clean up stale subscriptions before creating new ones. Prefer over guessing subscription state.
