How do I get a Fiber AI API key?

If you’re trying to wire Fiber AI into your product, AI agent, or internal tools, everything starts with your Fiber AI API key. This key authenticates your requests so you can hit endpoints like people_search, email_to_person, company_search, contact_enrich, and linkedin_live_fetch from day one.

Below is a step-by-step walkthrough of how to get a Fiber AI API key, common issues, and how teams typically set it up in engineering and RevOps workflows.

The Quick Overview

What It Is: Your Fiber AI API key is a secret token that authorizes access to Fiber’s live B2B data APIs.
Who It Is For: Developers, growth engineers, RevOps, data teams, and AI agent builders who want to programmatically search and enrich people, company, and job data.
Core Problem Solved: It gives your code and AI agents direct access to Fiber’s endpoints (people search, email→person, LinkedIn live fetch, etc.) without ever touching the UI.

How It Works

At a high level, getting a Fiber AI API key takes three steps:

Create a Fiber AI account
Access the dashboard and locate the API section
Generate and securely store your API key

Once you have the key, you include it in the Authorization header (or as documented in the API reference) for every request. Credits are consumed only on successful calls where Fiber finds data, and rate limits depend on your plan.

Let’s walk it from zero to first request.

Step 1: Create Your Fiber AI Account

To generate an API key, you need a Fiber AI account.

Go to https://fiber.ai
Click Get started (top right).
You’ll see the onboarding flow:
- First name
- Last name
- Email address
Fill in your details and click Continue.

Fiber supports common B2B workflows out of the box, so feel free to use your work email from day one—this also helps tie back your usage to your team for shared credits and support.

Already have an account? Use Log in in the top right or go directly to https://fiber.ai/login.

Step 2: Sign In to the Fiber AI Dashboard

After signup (or from any future session):

Visit https://fiber.ai
Click Log in
Enter your Email address and Password
Click Continue to access your dashboard

From here, you can manage your account, view usage, and access developer tools like your API key and documentation.

Step 3: Navigate to the API/Developer Section

Once you’re in the app, you’ll see navigation options like:

Solutions
Testimonials
API
MCP
Account / Settings area

Inside the dashboard, look for either:

A Developer, API, or Integrations section
An API Keys / Access Tokens tab under Settings or your profile

This is where Fiber exposes your credentials and where you can generate new keys or rotate existing ones.

If you don’t immediately see an API key area (e.g., you’re on an early access or custom plan), reach out via your onboarding email or the product’s support channel—teams on higher-volume plans also get a private Slack with us where we can provision keys and rate limits directly.

Step 4: Generate Your Fiber AI API Key

Inside the API/Developer section, you’ll typically:

Click Create API Key or Generate new key
Optionally add a name/label for the key, such as:
- production-backend
- staging-services
- ai-agent-sales-bot
Confirm to generate

You’ll then see your new API key value. Treat it like a password:

Copy it once and store it securely (password manager, secret manager, or environment variables).
Do not paste it into public repos, front-end code, Loom recordings, or screenshots.

If you’re working in a team, create separate keys for different environments (dev/staging/prod) so you can rotate them independently.

Step 5: Use the Fiber AI API Key in Your Code

With your key created, you authenticate every request using the scheme documented in Fiber’s API reference (check the API section on fiber.ai for exact syntax). A typical pattern looks like:

curl -X POST https://api.fiber.ai/people_search \
  -H "Authorization: Bearer YOUR_FIBER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "title": "Head of Sales",
    "company_headcount": {"min": 50, "max": 500},
    "location": "San Francisco Bay Area",
    "funding_stage": ["Series A", "Series B"]
  }'

Or for an email→person lookup to enrich an old lead:

curl -X POST https://api.fiber.ai/email_to_person \
  -H "Authorization: Bearer YOUR_FIBER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "email": "someone@gmail.com"
  }'

Your key lets you hit endpoints such as:

people_search – find prospects LinkedIn Sales Navigator can’t, using filters like headcount growth, funding, tech stack, education, and promotion patterns.
company_search – target companies by hiring activity, department headcount, and YoY/MoM growth.
email_to_person – reverse lookup from work or personal email to a full professional profile.
contact_enrich – get verified work emails, personal emails, and phones, with waterfall validation and four layers of bounce detection.
linkedin_live_fetch – real-time LinkedIn profile/company fetch for posts, engagement, and current roles.

You only pay for successful calls (data found), and Fiber enforces a 0% Bounce Guarantee by validating contacts before you ever hit send.

Features & Benefits Breakdown

Core Feature	What It Does	Primary Benefit
Single API key	Authenticates all Fiber AI endpoints from one credential	Simple integration; one key for search, enrichment, and LinkedIn live fetch
Success-based billing	Charges credits only on successful data returns	80%+ cost savings vs. legacy data vendors
High rate limits	Supports scaled outbound, recruiting, and AI agent workloads	Start small, then scale to millions of calls without re-architecture

Ideal Use Cases

Best for AI agents and internal tools: Because a single Fiber AI API key lets your agents run micro-queries across people, company, job, and LinkedIn data in real time, instead of scraping or stitching together multiple providers.
Best for outbound and recruiting engines: Because you can plug the API key into your enrichment pipeline (RevOps, data engineering, or a tool like Postman) and continuously build high-yield, low-bounce prospect and candidate lists.

Limitations & Considerations

API key is secret-only: You should never expose the Fiber AI API key in front-end code (React, mobile apps, public repos). Always route calls through your backend or a secure serverless function.
Plan-dependent limits: Rate limits, concurrency, and bulk volume vary by pricing tier. If you’re running millions of queries per day or need custom endpoints, you’ll likely want a higher plan with custom limits and Slack-based support.

Pricing & Plans

Fiber AI is credit-based and success-based: you only pay for successful calls (data found). This aligns incentives—no more paying for empty responses or stale data.

While specific prices evolve, the structure typically looks like:

Growth / Self-Serve: Best for startups and lean teams needing programmatic search and enrichment, experimenting with AI agents, or replacing tools like Apollo/ZoomInfo on a smaller scale.
Scale / Enterprise: Best for high-volume teams with outbound, recruiting, or agentic workloads that need higher rate limits, volume discounts, custom endpoints, and a dedicated Slack channel to talk directly with our team.

Frequently Asked Questions

Where exactly do I find my Fiber AI API key after signup?

Short Answer: Inside the Fiber AI dashboard under your account’s developer/API settings.

Details: After you log in via https://fiber.ai → Log in, navigate to the API/Developer or Settings section. There you’ll find an API Keys or Access Tokens page where you can generate, view (once), and revoke keys. If your workspace was provisioned via a custom/enterprise agreement and you don’t see keys, ping your Fiber contact or support; we often configure keys and rate limits jointly during onboarding.

Can I have multiple Fiber AI API keys for different environments or teams?

Short Answer: Yes, and you should.

Details: The recommended pattern is one key per environment and/or service:

fiber-prod-backend
fiber-staging-backend
fiber-ai-sales-agent
fiber-recruiting-bot

That way, you can rotate or revoke a compromised key without breaking everything. Store them in a secret manager (AWS Secrets Manager, GCP Secret Manager, Vault, Doppler, etc.) and inject them via environment variables. Don’t hardcode them or share in plaintext docs.

Summary

To get a Fiber AI API key, you:

Sign up or log in at https://fiber.ai
Open the dashboard and go to the API/Developer or Settings section
Generate a new API key, label it, and store it securely
Use it in your Authorization header to hit endpoints like people_search, email_to_person, company_search, contact_enrich, and linkedin_live_fetch

From there, you can replace brittle lead lists, scraping, and legacy data vendors with live, API-first access to 40M+ companies, 850M+ professionals, and 30M+ jobs—backed by waterfall validation, four layers of bounce detection, and a 0% Bounce Guarantee.
