No consent screen: your agent can connect it for you, but the key then passes through your chat. To keep it out of the model's context, paste it in the console instead. actionlake stores what you paste write-only, sealed under your tenant's key. - `api_key` Cognism API key (Cognism Prospector or Refresh > API keys ``` account { op: "connections.requirements", service: "cognism" } # free: exactly what to paste, and what is found for you ``` 3. 03 ### Make the first call.

Each one names the Cognism actions it will call, so you know what it reads and what it changes before you send it. 1. Read read Find the Cognism contacts with no email address, so we can clean them up. calls `cognism.contacts.redeem` Governance for Cognism ## Every write can wait for a yes. None of Cognism's actions is destructive. A key can still be held to reads, capped, and set so a person confirms every write. A destructive action runs only with `confirm: true`. Under the `human` policy the agent cannot confirm for itself: the run stops until a named person approves, in the console or from a signed link in an email. The cap on a key is refused before the call is sent, never after. a key for this connector ``` account { op: "keys.create", name: "cognism-agent", allowed_actions: ["cognism.*"], cap_calls: 2000, confirm_policy: "human_for_writes" } ``` Illustrative. Scoped to Cognism only, capped at 2,000 upstream calls, every write confirmed. Cost ## What Cognism costs on actionlake. Every Cognism action is one upstream call, the only thing actionlake bills.

The free call account { op: "connections.requirements", service: "cognism" } lists exactly what to paste. **Will an AI agent use up my Cognism API limit?** actionlake paces every call to the limits in the Cognism service file: 1,000 calls a minute per connection. Repeated reads are answered from cache (25 Cognism actions can be), which never reaches Cognism. **What does a Cognism action cost?** One upstream call, the only unit actionlake bills. A list that pages bills one call per page (2 Cognism actions page). Cache hits, searches, dry runs and calls Cognism refused with 401, 403, 429 or a 5xx are free.

It is built from Cognism's documentation as read on 23 October 2026. 25 actions in 5 areas, each one in the signed service file (version 1.0.0). **Does actionlake keep my Cognism data, and where?** actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to 5 minutes, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your Cognism credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models. **Which AI clients can use it?** Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names. ## More connectors like Cognism Shares the most action names with - [Explorium AgentSource 2](https://actionlake.com/connectors/explorium-agentsource) - [RocketReach 2](https://actionlake.com/connectors/rocketreach) - [Crunchbase 2](https://actionlake.com/connectors/crunchbase) - [Seamless.AI 2](https://actionlake.com/connectors/seamless-ai) - [6sense 1](https://actionlake.com/connectors/6sense) - [Blackbaud SKY API 1](https://actionlake.com/connectors/blackbaud-sky-api) Joins with, on shared entities - [ConnectWise PSA 2](https://actionlake.com/connectors/connectwise-psa) - [HaloPSA 2](https://actionlake.com/connectors/halopsa) - [Genesys Cloud CX 2](https://actionlake.com/connectors/genesys-cloud-cx) - [Simpro 2](https://actionlake.com/connectors/simpro) - [Acumatica Cloud ERP 2](https://actionlake.com/connectors/acumatica-cloud-erp) - [Exact Online 2](https://actionlake.com/connectors/exact-online) Browse - [All CRM & sales connectors](https://actionlake.com/connectors/category/crm-and-sales) - [All connectors](https://actionlake.com/connectors) - [How actionlake compares](https://actionlake.com/compare) actionlake is independent.
