Lusha API (2.0.0)

Lusha provides a RESTful API that allows you to query a comprehensive dataset of business profiles and company information.

All API requests should be made over HTTPS (SSL), and the response bodies are delivered in JSON format.

Data Source and Privacy

Please note that Lusha is a search platform, meaning the data provided is not created or directly managed by us. Instead, it is retrieved from publicly available sources and through contributions from trusted business partners.

For more information on how we collect, use, and handle business profiles, please refer to our Privacy Policy.

Authentication

To access the Lusha API, you must authenticate your requests using your API key. This key is unique to your account and is used to identify your usage of the API.

How to Authenticate

When making an API call, include your API key in the api_key header of the request.

Important Notes

  • To obtain your API key, please visit the following link: https://dashboard.lusha.com/enrich/api
  • Your API key is sensitive and should be kept private. Do not share it with anyone outside of your organisation.
  • The API key is used to track and manage your usage of the API, so ensure it is protected from unauthorised access.

Available Endpoints

  • Person Enrichment: Get contact information for individuals
  • Company Enrichment: Get detailed company information
  • Prospecting: Search and enrich contacts and companies based on specific criteria
  • Account Management: Monitor your API credit usage

Rate Limiting

Lusha API enforces rate limiting to ensure fair usage and protect against excessive load.

  • General Rate Limit: You can make up to 50 requests per second to each API endpoint
  • Credit Usage API: Has a specific rate limit of 5 requests per minute

Rate Limit Headers

To monitor your current rate limit status, check the HTTP response headers in your API calls:

HeaderDescription
x-rate-limit-dailyThe total number of requests allowed per day under your current plan
x-daily-requests-leftThe number of requests remaining in your daily quota
x-daily-usageThe number of requests you have made in the current daily period
x-rate-limit-hourlyThe total number of requests allowed per hour under your current plan
x-hourly-requests-leftThe number of requests remaining in your hourly quota
x-hourly-usageThe number of requests you have made in the current hourly period
x-rate-limit-minuteThe total number of requests allowed per minute under your current plan
x-minute-requests-leftThe number of requests remaining in your current minute window
x-minute-usageThe number of requests you have made in the current minute window

Notes on API Rate Limiting

  • If you exceed the rate limit, the API will return a 429 (Too Many Requests) error.
  • To ensure a smooth experience, respect the rate limits defined by your subscription tier.
  • Daily limits vary based on your billing plan — higher tiers have higher quotas.
  • You can programmatically track your usage through these response headers:
    • X-RateLimit-Remaining-Daily
    • X-RateLimit-Reset-Daily
  • It is strongly recommended to implement logic that:
    • Monitors these headers
    • Pauses or retries requests accordingly
    • Helps avoid hitting the limit and ensures reliable operation

Error Codes

Lusha API uses standard HTTP response codes to indicate the status of your request. These codes help you understand whether the request was successful or if there was an issue.
