Anti-Malware — entry 012 of 15
URLhaus
URLhaus, another abuse.ch project, crowdsources and publishes malware-distribution URLs so security tools can block them, offering bulk recent-URL feeds and single-URL/hash lookups via a JSON REST API. A live POST to urlhaus-api.abuse.ch's recent-URLs endpoint without a key returned {"error": "Unauthorized"}, and a bogus Auth-Key returned {"query_status": "unknown_auth_key"}, confirming abuse.ch's shared Auth-Key migration and correcting the stored auth from None to API Key. Neither call returned an Access-Control-Allow-Origin header, correcting cors from yes to no; access itself remains free under the same abuse.ch fair-use policy as its sibling APIs.

- Sign up with the provider to get an API key.
- Send it on every request as a header
Authorization: <key> - The exact header isn't documented — Authorization is a common default; confirm in the provider's docs.
Your key is stored only in this browser (localStorage) and sent directly to the API — never to greatapis.
