There is a non-zero probability that IDs may change in the future, and this should not result in any breaking changes. ## OpenAPI ````yaml /openapi-v1.yaml get /v1/tx-subscriptions/{subscription_id}/wallets/count openapi: 3.0.3 info: version: 1.0.0 title: REST API description: REST-like API provides access to rich Zerion ecosystem. contact: name: Zerion API url: https://developers.zerion.io/ email: api@zerion.io servers: - description: Production API url: https://api.zerion.io security: - APIKeyBasicAuth: [] tags: - name: wallets description: >- Operations related to wallets, such as portfolio charts, positions, and transactions. - name: wallet sets description: >- Operations on a wallet set — aggregated portfolio data across at most one EVM address and one Solana address queried together. - name: fungibles description: >- Operations related to fungible assets, such as list them all, search or get by ID. - name: chains description: Operations related to chains, such as list all chains. - name: swap description: Operations related to swapping and bridging assets. - name: gas description: Operations related to gas. - name: nfts description: >- Operations related to non fungible assets, such list them, search or get by ID. - name: dapps description: >- Operations related to decentralized applications, such as list them all, search or get by ID. - name: subscriptions to transactions description: Operations related to subscriptions to transactions. paths: /v1/tx-subscriptions/{subscription_id}/wallets/count: get: tags: - subscriptions to transactions summary: Count wallets within subscription description: > This endpoint returns the count of wallets within a specific subscription by subscription ID. > NOTE: Consider all IDs as abstract strings, without making any assumptions about their format or relying on such assumptions.
