If missing, stop and tell the user to obtain a key from Lensmor, then set:

export LENSMOR_API_KEY=your_key_here

Never print the key value.

Step 2: Choose the Mode

Use event-specific list when the user names a show, supplies an event_id, or asks who is exhibiting at an event.

Use cross-event discovery when the user supplies at least one of:

company_url — the user's company website
target_audience — a concise company-profile or market phrase

If the user asks for event-specific results but has no event ID, resolve it with:

GET https://platform.lensmor.com/external/events/list?keyword={show+name}

Select the correct items[].id or items[].eventId only after confirming the year and edition. Do not use query=; it is not a supported filter.

Step 3A: Event-Specific List

Endpoint: GET https://platform.lensmor.com/external/exhibitors/list

Required query parameter:

event_id

Optional query parameters:

keyword, country, category, industry
jobTitle, managementLevel, department
personnelLimit, page, pageSize

Example:

event_id=12740&page=1&pageSize=20&industry=Medical%20Equipment%20Manufacturing

This endpoint returns event-scoped exhibitor records plus semantics describing preview or full access. It does not automatically unlock the event.

Step 3B: Cross-Event Discovery

Endpoint: POST https://platform.lensmor.com/external/exhibitors/search

Request with a target audience:

{
  "target_audience": "medical devices",
  "page": 1,
  "pageSize": 20
}

Or request with a company URL:

{
  "company_url": "https://example.com",
  "page": 1,
  "pageSize": 20
}

Do not send event_id in this request. The result is heuristic discovery across Lensmor's wider exhibitor dataset, not proof that every result belongs to a named event.

Step 4: Interpret the Response

Both modes return a paginated envelope:

{
  "items": [],
  "total": 138,
  "page": 1,
  "pageSize": 20,
  "totalPages": 7,
  "hasMore": true
}

Useful item fields include:

Field	Meaning
`companyName`, `website`, `linkedinUrl`	Company identity and public links
`industry`, `categories`, `employeeCount`, `country`	Company profile signals
`techStacks`	Detected technologies; may be empty
`matched_event_ids`	Event IDs attached to the returned record
`isRecommended`, `recommendationRank`, `matchScore`, `matchTier`, `matchReason`	Recommendation metadata when actually populated
`buyingSignals`, `buyingSignalStatus`	Available buying-signal evidence and processing state

For event-specific mode, also read:

semantics.accessMode: preview or full
semantics.counts.actualTotal, visibleTotal, remainingLockedCount
semantics.unlock.requiredForMoreResults and credits
semantics.guidance.message

Do not describe results as ICP-matched or AI-ranked unless recommendation fields are populated. A keyword or audience match alone is only a discovery result. When event-scoped rows have no populated recommendation evidence, call them exhibitor records; do not call them matching exhibitors.

Event-scoped rows are Lensmor exhibitor records. Do not relabel them as registrations, official registrations, confirmed exhibitors, confirmed attendance, or organizer-verified records unless the API returns that provenance explicitly. Do not describe the event association as enrollment. Say only that the company appears in Lensmor's event-scoped exhibitor records. If the API's free-text access message uses matching exhibitors, do not quote that phrase; normalize it to exhibitor records while preserving the numeric counts, action type, and credit price.

Step 5: Format the Output

For event-specific mode:

## Exhibitors — [Show Name]

Found [actualTotal] event records; [visibleTotal] are currently accessible.
Access: [preview/full] · Showing page [page]

| Company | Industry | Employees | Country | Evidence |
|---|---|---:|---|---|
| [Company](website) | [industry] | [employeeCount] | [country] | Event ID [matched_event_ids] |

[semantics.guidance.message, if relevant]

For cross-event discovery:

## Exhibitor Discovery Results

Found [total] records for: [company URL or target-audience phrase]

| Company | Industry | Employees | Country | Why returned |
|---|---|---:|---|---|
| [Company](website) | [industry] | [employeeCount] | [country] | [returned field evidence only] |

Error and Access Handling

Condition	Response behavior
400	Check required fields and mode-specific parameters
401	The API key is invalid or expired
404 in event mode	Resolve the correct current-edition event ID
429	Wait and retry after the rate-limit window
Empty results	Broaden only the filters relevant to the active mode
Preview truncated	Report visible/remaining counts; do not unlock automatically

An event unlock can consume the credits shown in semantics.unlock.credits. Ask the user before calling an unlock endpoint. When an unlock is available, report the returned action type and exact credit price. Do not tell the user to contact support unless the API says the action is unavailable.

Follow-up Routing

Need profile-ranked accounts for an event → trade-show-lead-recommender
Need relevant contacts at a returned company → trade-show-contact-finder
Need outreach copy → booth-invitation-writer
Need to judge the event first → trade-show-fit-score

Output Rules

Never output LENSMOR_API_KEY or raw authorization headers.
Keep event-specific and cross-event modes visibly distinct.
Never claim that cross-event discovery results exhibit at a named show unless matched_event_ids supports it.
Never invent ICP rationale; use only returned company, recommendation, and signal fields.
When routing to contact search, say find relevant contacts; do not promise decision-makers or verified authority.
Never use decision-maker, budget holder, or verified-authority language anywhere in the output, including explanatory text after a routing label. trade-show-contact-finder returns relevant contact records only.
Do not promise role, geography, or other filtering after unlock unless the called endpoint explicitly supports that filter. Report only the returned access expansion.
Do not imply that trade-show-lead-recommender requires an event unlock or will necessarily return ranks or scores. It is a separate endpoint whose recommendation fields may be empty.
Preserve preview/full access semantics and credit guidance.
If matchScore, matchReason, or recommendation rank is null, say recommendation evidence is unavailable.
Format public URLs as Markdown links.
End with one or two relevant next actions.
Call event-scoped rows "Lensmor exhibitor records"; never call them registrations or independently confirmed participation.
