Build event intelligence workflows with the Lensmor API. Use it to discover trade shows, evaluate event fit, inspect exhibitor and personnel data, and unlock contact details when your team is ready to act. Use this documentation to authenticate, make your first request, and integrate Lensmor event, exhibitor, personnel, contact, and recommendation resources into your own workflows. Current documentation version: v0.23.0

Base URL

https://platform.lensmor.com All endpoint paths in this documentation are relative to this base URL. For example, GET /external/events/list resolves to GET https://platform.lensmor.com/external/events/list.

What you can build

Find the right events

Search, filter, and rank trade shows by geography, category, quality, and profile fit.

Evaluate exhibitor opportunities

Match target accounts or buyer profiles against exhibitor data and related event presence.

Unlock event-level coverage

Move from preview results to full exhibitor and personnel access for a selected event.

Enrich contacts

Start asynchronous email unlock jobs and poll task status until contact data is ready.

​
Which endpoint should I use?

1

Authenticate every request

Create a user API key and send it as Authorization: Bearer sk_your_api_key.
2

Check credits before paid workflows

Call GET /external/credits/balance before event unlocks, email unlocks, or reverse event searches.
3

Discover the event or account context

Use Events, Exhibitors, Personnel, Contacts, or Profile Matching endpoints depending on your workflow.
4

Respect preview and rate-limit semantics

Read semantics metadata, handle 402 Payment Required, and back off on 429 Too Many Requests.

​
First request

If the request succeeds, continue with the Quickstart guide. If it fails, check Authentication and Error conventions.
