API and integrations

The API

• Create API keys in the dashboard on the API Keys page.
• The Developer Hub at app.1lookup.io/developer-hub has quickstart

snippets, an in-browser tester, and integration guides.

• API lookups spend the same credits as dashboard lookups, at the same

per-product costs (shown on the Billing page in the dashboard).

• For high sustained throughput use the Bulk API: submit an array

of inputs as one job, get a job id, poll progress, fetch results.
It is far better than looping single requests, and it is the answer
to most rate-limit problems.

Integrations

• n8n: official 1Lookup node.
• Make.com: 1Lookup app.
• MCP: 1Lookup has an MCP server, so AI agents and assistants can

run lookups directly against your account.

• Zapier: not yet available.
• The Developer Hub lists everything that is live, with setup guides.

Common questions

• Test without paying? The free tools on 1lookup.io and the 7-day

trial both work, and the trial covers API testing. The free plan
(25 credits/month) is for dashboard use; API calls need a trial or
paid plan.

• Webhooks? Two exist today, both signed: number monitoring

alerts, and Bulk API job-completion webhooks (set webhook_url on the
job). Tell
us in the chat what other webhook events you need; requests reach the
product team.

• Hitting 429 / rate limits? Switch to the Bulk API. If you are

already on bulk at real volume, write to us with your plan and
numbers: sustained-volume needs are an account-level conversation.
