# Fiber B2B company and people data

Fiber.ai data through the Exa Agent: search across 40M+ companies and 850M+ people, company and person lookups, email reverse lookup, LinkedIn signals. Needs query. Served by Exa.

Fiber.ai data through the Exa Agent: search across 40M+ companies and 850M+ people, company and person lookups, email reverse lookup, LinkedIn signals (job changes, headcount, fundraising) and contact reveal (work email, personal email, phone). Ask in natural language and, for structured output, pass output_schema naming the fields you want from Fiber.ai. Examples: "Ten Series A fintech companies in New York with 50 to 200 employees: name, domain, headcount, last funding." "Who is the current head of marketing at Vercel, with their LinkedIn URL." "Reverse-look up jane@example.com to a person and their company." Price: metered Exa usage plus any attached data partner charges. An explicit spending limit is sent to Exa (default $1); only auto and ultra effort are supported so that the limit applies. Actual costDollars.total is billed. Asynchronous results are available through exa/agent-run-get.

## Published example

This is the provider tool’s published example. Replace example values with the user’s requested inputs, respecting the schema; do not execute an example merely to test a connection.


```json
{
  "tool_id": "exa/fiber",
  "input": {
    "query": "The current head of marketing at Vercel: name, title and LinkedIn URL, from Fiber.",
    "effort": "auto",
    "max_cost_usd": 1
  }
}
```

## Execute and retrieve

Inspect again before execution, explain the price and obtain the required authority. Use MCP run_tool or POST /v1/run with this tool ID, valid input and an idempotency key. Save the returned run ID and follow the actual state. If Agentik answers that the tool is temporarily unavailable, do not retry it blindly; use discovery to propose an alternative.

This tool uses deferred settlement. Follow its returned task/run instructions; preserve the existing reservation until the result is reconciled.

A partial or uncertain result can still have consumed provider resources. Consult [billing](/docs/billing.md), [idempotency](/docs/idempotency.md) and [asynchronous results](/docs/async.md).
