Interactive example · fictional data

Check and enrich records. Directly via API.

Send contacts as JSON from n8n, Make or your own code. A check returns findings and suggested fixes for each affected row. A lookup returns the record with the fields it found. Neither call needs a ListPlus list.

Your list decides what happens next.

Once the rules are in place, your agent only needs to add contacts. Each row keeps its data, findings and status. The list starts enrichment when a contact fits your ideal customer profile.

New and existing rows ListPlus matches by email, LinkedIn profile or name and company. The import reports which rows were added, merged or rejected and why.
Each row has its own destination A qualified contact can go to n8n, your CRM, a sequencer or a second list. An unresolved finding can send another contact to your team for review.

Choose what your agent can change.

An owner or admin shares each list with a connection. Choose a permission level to see what it allows.

The connection has a daily budget. Paid lookups can be estimated first and capped per call. The activity log shows tasks and credits.

Your agent can hide contact records. Your team can restore them in the list.

Before enrichment

Mobile number and LinkedIn profile for one selected contact.

Estimated

5 Credits

At most

23 Credits

That is at most $0.81 on Pro.Try the selection and estimate How are calls charged?

Estimate and ceiling

For the selected records and fields, your agent receives an estimate with a maximum cost. The response includes a cost message for the chat (tell_your_user).

Cost by task

A field that already has a value incurs no lookup cost. A billable page of up to 25 people from the lead database costs 2 credits. Loading a company costs 0.25 credits. Market counts are free.

Per connection

Paid steps use workspace credits. A daily budget of 0 allows only free actions. The activity log records the action, record count, field names and credits.

Read rows and run checks

Add, update and tag rows –

Enrich and hand off to a pipeline –

Set up A separate permission, off by default. Enable it to let your agent create lists, add score columns and configure triggers within its list permissions.

Column protection and access

Read + check, Edit or Full

Read and run the checks; also add, update, set statuses and tags; also enrich, fill AI columns and hand records to pipelines.

Columns and write protection

Hide columns it should never see, choose the ones it may write, let it fill only empty cells, limit it to some sublists.

Its own lists

Lists your agent creates for a search or a workflow are automatically shared with that connection.

Revoke at any time

A revoked connection stops at once. Running jobs are cancelled; you pay only for what they found.

Inspect the tools behind the conversation.

The same actions are available through MCP and REST. The agent brief lists their inputs, costs and permissions.

MCP

https://listplus.ai/mcp (streamable HTTP). Clients that support OAuth sign in when a call needs it; others send Authorization: Bearer lpk_….

REST

POST https://listplus.ai/a/v1/{action} with a JSON body and your key as a Bearer token. Anything that speaks HTTP works — n8n, Make, Zapier, your own code.

Before you connect

Can I try it on the free plan?

Yes. Connecting your AI is included on every plan. Standard checks cost no credits. Paid actions use workspace credits at the same price as the app. One credit costs $0.035 on Pro or $0.06 on Basic in USD.

When does a task create a list?

Direct checks and enrichment return their results to the caller. A lead database search saves its results and subsequent pages in a workspace list. Your team can review the rows, adjust the score and follow handoffs.

Can my agent delete anything?

Contact records are preserved. Moving a contact hides its source row. Hidden rows leave checks, rules, enrichment and sync until your team restores them. Removing a column or a rule requires both Full list access and the connection’s Set up permission.

How does ListPlus fit alongside Clay or Deepline?

Bring contacts from your existing workflow into a shared review list. ListPlus flags issues and CRM matches. Your team chooses which rows go to the configured pipeline.
