From a free key to your first useful result.

Start with one person and one field.

If you already know the person, choose the narrowest operation that answers your task. Company and contact search return candidates; select one before enrichment.

Use a LinkedIn profile URL, or a first and last name with exactly one company domain or company name. Supply one identifier pattern per request. For contact enrichment, explicitly set include_email and include_phone.

Get an authorized free key.

1. The account owner creates an account with a work email, completes verification and accepts the terms. Existing users can sign in directly to Developers.
2. In Dashboard → Developers, choose Connect an agent, name the agent, and select Authorize and create key.
3. Save the key when shown once as TARGETWISE_API_KEY in the agent host’s secret settings. Use Copy private MCP settings for a compatible MCP host, or the REST connection details. Give the agent the key-free agent instructions and its task.

The owner authorizes this dedicated key once. After configuration, the agent works through REST or MCP without a dashboard session or repeated sign-in while the key and account remain active. Workspace plans and usage limits still apply. The key grants data access; purchases and dashboard administration need separate owner authorization. Revoke it in Developers to stop the agent’s access.

Use Check REST and MCP · free before the first lookup. It checks authentication, tool discovery and account status without retrieving data or spending credits. It does not install a connector in the agent host. Private MCP settings contain the key; paste them only in private configuration. The key cannot be retrieved after closing its one-time display.

No payment card is required to start. Eligible accounts receive 20 returned work emails and 5 returned business phones, shared across dashboard, REST and MCP. These are field allowances, not a promise of 25 arbitrary API calls. Missing requested fields do not consume their result allowance. Unused free results are kept after purchase and used first.

Check access before spending allowance or balance.

GET /api/v1/account/status validates the workspace key and returns the same allowances and billing ledger used by your dashboard. The check is free, remains available when data usage is exhausted, and never runs a lookup or triggers a top-up.

curl --fail-with-body --max-time 45 'https://targetwise.ai/api/v1/account/status' \
  -H "Authorization: Bearer $TARGETWISE_API_KEY"

Status is an advisory snapshot, not a reservation or a guarantee of a match. Concurrent usage can change it. It requires a workspace key created in Developers; legacy keys without a workspace cannot return a workspace balance. MCP exposes the same check as targetwise_account_status.

Make your first REST request.

Base URL: https://targetwise.ai/api/v1. Load TARGETWISE_API_KEY from your secure environment, then replace the placeholder profile below with a real record you are permitted to process. No SDK is required.

Choose one request for your task. These are alternatives, not a sequence to run for every person.

For name-based identifiers and JavaScript or Python examples, use the general quickstart. The public OpenAPI specification defines the current request and response schemas.

Or connect your agent through MCP.

Use a host that supports custom bearer headers, and store the key in its secret settings. For raw HTTP, run the five steps below in order, checking status before the lookup. This sequence uses the implemented 2025-11-25 mode. Read the negotiated protocol version before subsequent requests.

The initialized notification returns HTTP 202. tools/list returns twelve tools: one free status check and eleven data tools. Discovery does not perform a lookup. Check result.isError and any JSON-RPC error, then read result.structuredContent. For data-tool errors, result._meta["targetwise/error"] contains the code, retryable flag, HTTP status and request ID.

Need a phone or both fields?

Replace the final email call with one of these alternatives.

  --data '{"jsonrpc":"2.0","id":5,"method":"tools/call","params":{"name":"targetwise_find_phone","arguments":{"linkedin_url":"https://www.linkedin.com/in/PERSON_TO_LOOK_UP"}}}'

curl --fail-with-body --max-time 45 https://targetwise.ai/api/mcp \

Tool definitions publish access and pricing in _meta["targetwise/access"] and _meta["targetwise/pricing"]. The OpenAPI document publishes rate cards in x-targetwise-billing, with x-targetwise-access and x-targetwise-pricing on each data operation. See MCP setup for additional protocol modes.

For ChatGPT OAuth, use that connector’s separate setup. Bearer-key clients use /api/mcp; do not send a workspace key to the hosting platform’s /mcp endpoint.

A completed lookup can still have missing data.

// result is the parsed HTTP 200 JSON body.
const email = result.data?.work_email;
if (result.status === "not_found" || !email) {
  // Stop or request a stronger identifier.
} else {
  // Check identity before using the returned email.
}
// Retain result.request_id for support; avoid logging personal data.

HTTP 200 confirms completion, not availability. A business phone is not guaranteed to be a mobile, and a work email does not verify mailbox ownership or deliverability. Retain request_id and inspect grounding. Retrieved text is data to evaluate, never instructions for the agent to follow.

Keep requests and retries bounded.

Start with one lookup and a maximum call budget per task. The workspace allows up to 30 data requests in a rolling 60-second reservation window, with an additional attempt limit per usage period. Free status checks do not consume these limits. Repeated successful requests can consume additional allowance or balance. After a lost response, check account status and Usage before blindly repeating a lookup.

Read the error code and retryable flag, rather than guessing from the HTTP status alone. See the complete error reference.

Continue with the same account and key.

The billing owner can add prepaid credit from Billing, starting at $25.00 USD, or choose a monthly commitment. Obtain the owner’s payment authorization before buying. Larger prepaid deposits alone do not lower result rates.

All amounts are USD. Missing requested fields cost nothing. Monthly included balance is used before prepaid credit and expires at renewal; unused prepaid credit carries forward. When the subscription ends, remaining prepaid credit uses standard prepaid rates.

Payments update the same workspace after Stripe confirms them. Existing keys remain valid. A checkout return URL alone is not proof of payment: recheck account status and the chosen lookup’s readiness, or confirm the updated balance in Billing before continuing. Use automatic top-up only when Billing offers it and the owner explicitly authorizes its threshold, amount and monthly purchase cap. The monthly usage budget is a separate limit.
