ProjectDiscovery

ProjectDiscovery builds the open-source security toolchain trusted across offensive security and attack-surface management -- Nuclei, Subfinder, httpx, Katana, Naabu, dnsx and more -- and the ProjectDiscovery Cloud Platform (PDCP) that operationalizes them for continuous exposure management. Its REST API at api.projectdiscovery.io exposes asset discovery and enumeration, template-driven vulnerability scanning, credential-leak monitoring, scan scheduling, configuration, and template management, authenticated with a single X-API-Key header over HTTPS. Founded by the creators of Nuclei and backed by Accel, ProjectDiscovery serves security teams automating attack-surface discovery and vulnerability detection at scale.

ProjectDiscovery publishes 20 APIs on the APIs.io network, including Asset API, assets API, chaos API, and 17 more. Tagged areas include Company, Cybersecurity, Security, Vulnerability Scanning, and Attack Surface Management.

ProjectDiscovery’s developer surface includes documentation, API reference, getting-started guide, engineering blog, pricing, signup flow, support, and 24 more developer resources.
