[Skip to content](#%5Ftop) # Threat Intelligence APIs Cloudflare provides a series of endpoints covering various areas of internet security and insights. Based on your Cloudflare plan type, the [limit](https://developers.cloudflare.com/security-center/intel-apis/limits/) of API calls will vary per month. | Intelligence Endpoint | Definition | | ------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------- | | [ASN Intelligence](https://developers.cloudflare.com/api/resources/intel/subresources/asn/methods/get/) | Provides an overview of the Autonomous System Number (ASN) and a list of subnets for it. | | [Custom Indicator Feed Download](https://developers.cloudflare.com/api/resources/intel/subresources/indicator%5Ffeeds/subresources/downloads/) | Provides the ability to download any custom indicator feeds that users create. | | [Domain Intelligence](https://developers.cloudflare.com/api/resources/intel/subresources/domains/methods/get/) | Provides security details and statistics about a domain. | | [Domain History](https://developers.cloudflare.com/api/resources/intel/subresources/domain%5Fhistory/methods/get/) | Provides historical security threat and content categories that are currently and previously assigned to a domain. | | [IP Intelligence](https://developers.cloudflare.com/api/resources/intel/subresources/ips/methods/get/) | Provides the geolocation, ASN, infrastructure type of the ASN, and any security threat categories of an IP address. | | [Passive DNS by IP](https://developers.cloudflare.com/api/resources/intel/subresources/dns/methods/list/) | Provides a list of all the domains, including first seen and last seen dates, that have resolved to a specific IP address. | | [Phishing Intelligence](https://developers.cloudflare.com/api/resources/brand%5Fprotection/methods/url%5Finfo/) | Provides phishing details about a URL. | | [Miscategorization Intelligence](https://developers.cloudflare.com/api/resources/intel/subresources/miscategorizations/methods/create/) | Enables users to submit requests for modifying a domain's category, subsequently undergoing review by the Cloudflare Intelligence team. | | [Priority Intelligence Requirements](https://developers.cloudflare.com/api/resources/cloudforce%5Fone/subresources/requests/subresources/priority/methods/create/) | Provides a structured approach to identifying intelligence gaps, formulating precise requirements, and organizing them into categories. | | [Request for Information](https://developers.cloudflare.com/api/resources/cloudforce%5Fone/subresources/requests/methods/create/) | Creates a targeted inquiry for specific intelligence insights to help organizations understand and respond to imminent security threats and vulnerabilities. | | [Threat Events](https://developers.cloudflare.com/api/resources/cloudforce%5Fone/subresources/threat%5Fevents) | Allows customers to look into the Cloudflare telemetry and threat actor activity on the Cloudflare network. | | [WHOIS](https://developers.cloudflare.com/api/resources/intel/subresources/whois/methods/get/) | Provides the WHOIS registration information for a specific domain. | | [DDoS Botnet Threat Feed](https://developers.cloudflare.com/ddos-protection/botnet-threat-feed/)(early access) | Provides information to service providers about their own IP addresses that have participated in HTTP DDoS attacks as observed from Cloudflare's global network. | | [Cloudforce One](https://developers.cloudflare.com/api/resources/cloudforce%5Fone/subresources/requests/subresources/assets/methods/create/) | Enable users to list, delete, get, or update a request asset. | | [Brand Protection API](https://developers.cloudflare.com/api/resources/brand%5Fprotection/) | Provides the ability to create and delete queries, download matches for logo and string queries, read matches for logo and string queries. | ## API Examples Below you can find examples of Threat Intelligence API calls.
