AbuseIPDB vs Scanii

AbuseIPDB is a crowdsourced IP, domain, and URL reputation database where network operators report malicious activity like brute-force attempts, spam, and port scans. A live GET against the real gateway, api.abuseipdb.com/api/v2/check, returned a 401 with an invalid key rather than a CORS-enabled response, reconfirming API-key auth over HTTPS and resolving cors to no. A free Individual tier allows 1,000 checks a day forever with no card required, while paid Basic/Premium/Enterprise plans raise the daily ceiling for high-volume users.

Scanii is a REST API that scans uploaded files, images, and text for malware, unsafe imagery, and inappropriate language across more than 100 image formats and 20+ languages, returning findings, checksums, and content metadata as JSON. A live GET and OPTIONS preflight against api.scanii.com/v2.2/files both returned Access-Control-Allow-Origin: *, and the GET's 401 carried a WWW-Authenticate: Basic realm="Scanii API" header, correcting the stored auth from API Key to Basic Auth (the API key is used as the Basic-auth username, its secret as the password) over HTTPS. New accounts start with free trial credits before moving to metered Starter/Plus/Enterprise plans billed per file scanned.
