How this service works
Interpreted wallet data for more than 40 chains and Solana: portfolios, DeFi positions, PnL, transactions and NFTs. REST for apps, x402 pay-per-call for agents.
Output
Returns a JSON object with a `data` field containing the subscription resource, including its `id`, `type`, and `attributes` representing the wallet count. Also includes a `links` object with a self-referencing URL for the resource.
Example use cases
Monitor subscription wallet membership
“Can you check how many wallets are enrolled in my Zerion tx subscription with ID 'sub_xyz789'? I want to make sure all expected addresses are still being tracked.”
Verify subscription scale before billing
“Before I renew my subscription plan, can you tell me the current wallet count for Zerion subscription 'sub_prod_001' so I know how many wallets I'm paying to monitor?”
Audit multi-wallet DeFi tracking setup
“I set up a transaction subscription to track several wallets across chains — can you pull the wallet count for Zerion subscription 'sub_defi_42' so I can confirm all of them got added correctly?”
Technical details
Endpoint
GEThttps://api.zerion.io/v1/tx-subscriptions/%7Bsubscription_id%7D/wallets/count?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify or audit the number of wallet addresses enrolled under a specific Zerion transaction subscription. Prefer this over manually iterating wallet lists when you only need the count metric, or when automating subscription health checks and billing audits.
