Pro supports the same core IOC lookups and adds enriched context. Response fields and structure can differ between tiers. Actor context, behavior mappings and evidence depend on the intelligence available for each indicator.

Compare API fields by IOC type

Representative fields for full IOC responses are listed below. Field names and structure can differ between Basic and Pro; compact views request reduced detail where supported.

Files
Basic: MD5, SHA1, SHA256, SSDEEP, TLSH, imphash, file names, size and type.
Pro: Core file identity plus Richhash, MIME type, compile and creation times, signature information, PE headers and sections, imports, exports, resources, behavior records and tags, outbound connections, DNS requests and C2 candidates.
IP addresses
Basic: IP address, IP version and country.
Pro: IP address and version, public-address status, CIDR, network range, location, ASN, AS owner, ISP, organization, hosting provider and network classification; observed services, ports, protocols and banners, certificates, DNS observations and WHOIS information.
Domains
Basic: Domain name and TLD.
Pro: Domain name, TLD, root domain and subdomain; domain profile, DGA score and risk indicators, domain age, WHOIS registration details, DNS records, passive DNS observations, certificates and TLS subject alternative names.
URLs
Basic: URL identifier, URL and host.
Pro: URL identifier, URL, host, TLD and categories; HTTP status, response length, content SHA256 and response headers.
Assessment & observations
Both tiers can return maliciousness, severity, confidence, family, detection signals, tags and first / last seen timestamps. Basic includes assessment status and a crowd signal rate. Pro includes threat type, an actor-presence signal and crowd context where available. Pro file behavior records can include signature matches and MITRE ATT&CK / MBC mappings, with descriptions, severity and tags. Reported actor associations and C2 candidates support investigation; they are not conclusive attribution.
Related records & pagination
Both tiers support related IOC queries. Available relationship types depend on the source indicator; IP and domain queries can also return WHOIS, certificate and resolution records. Use the returned cursor for additional pages. API results are not capped at the few items selected for a website report; requested page size, service limits, permissions and credits still apply.

Both tiers also include website access. Website reports provide a focused view of the intelligence; their field summaries and display counts do not define the API response.

Fields depend on the indicator, available intelligence, response view and account filtering. DNS and service observations do not imply complete historical coverage or an active scan. See the API documentation for requests, pagination and credit usage.

Before you choose

Do I need a trial key before purchasing?

No. When online subscriptions are available, you can purchase directly using the links above. If you already have a key, use the same account email so we can match your purchase. Contact us if your payment email differs. Never send your API key in a payment note.

Can I upgrade an existing key?

Yes. We confirm the account and adjust its access after verifying your purchase. If you already have a paid subscription, contact us first to arrange a plan change and avoid duplicate subscriptions.

How are credits used?

Website investigations and API requests share your credits. At the standard rate, an IOC lookup costs 1 credit, plus 1 credit per started block of 20 requested relationships. With relationship access enabled, a website lookup normally costs 2 credits for either Basic or Pro (limit 20). Fewer displayed results do not reduce that charge. Standalone relationship requests are charged by their requested page size. See the API documentation for usage details.

Can I use a plan commercially? What is separate?

Feeds, malware samples, historical datasets and bulk raw-data redistribution need separate arrangements. Paid API plans support research, internal business use, software/SaaS integration and MSSP services, including displaying intelligence to your customers. Sharing or reselling API keys and reselling standalone data access require a separate agreement.

Files are hashed locally in your browser and never uploaded. Only the SHA-256 is sent for lookup. Standard query quota applies.
