Immunefi

Immunefi Bug Bounty Programs API

An unauthenticated, read-only JSON endpoint published on Immunefi's own domain that returns the complete catalog of bug bounty programs listed on the platform. Each record carries the project name and slug, program and product type, ecosystems, languages, maximum bounty, reward token, KYC and invite-only flags, launch and update dates, the full assets-in-scope list, the reward table keyed by severity and asset type, prioritized and out-of-scope impacts, program overview and rules prose, and any linked audits. The route serves the entire collection as a single JSON array; there is no filtering, pagination, or per-program path.
