Designed to be piped into a SIEM ingestion pipeline. ## Output - `format=cef` (default): One CEF line per IOC. Example header: `CEF:0|SOCDefenders|ThreatIntel|1.0|ipv4|Malicious IPv4|6|src=192.168.1.1 ...` - `format=syslog`: RFC 5424 lines with structured-data sections. ## Ingestion examples - **Splunk**: configure a TCP/UDP listener on port 514 and `curl ... | nc splunk.example.com 514` - **Sentinel**: forward via Logstash + Common Event Format connector - **rsyslog**: pipe directly with `logger -p local0.info -t socdefenders` Requires the **Pro plan** (`read:cef` scope). ## OpenAPI ````yaml https://socdefenders.ai/api/openapi.json get /api/v1/iocs/cef openapi: 3.0.3 info: title: SOC Defenders Threat Intelligence API description: >- # Overview The SOC Defenders Threat Intelligence API provides programmatic access to aggregated threat intelligence from 30+ cybersecurity sources. Export IOCs (Indicators of Compromise) in various formats including JSON, CSV, STIX 2.1, MISP, CEF, and OpenIOC. ## Authentication All API endpoints require authentication using an API key. Include your key in one of these ways: - **Authorization Header** (recommended): `Authorization: Bearer sk_live_xxx` - **X-API-Key Header**: `X-API-Key: sk_live_xxx` - **Query Parameter**: `?api_key=sk_live_xxx` ## Rate Limiting Rate limits vary by tier. When limits are exceeded, the API returns a 429 status code. | Tier | Requests/min | Requests/day | Lookback | Formats | |------|-------------|--------------|----------|---------| | Free | 10 | 1,000 | 1 day | JSON / CSV | | Pro ($299/mo) | 1,000 | 1,000,000 | 365 days | All (STIX, TAXII, MISP, CEF, OpenIOC, Sigma) | Rate limit headers are included in all responses: - `X-RateLimit-Limit`: Maximum requests per minute - `X-RateLimit-Remaining`: Requests remaining in current window - `X-RateLimit-Reset`: Unix timestamp when the limit resets ## Error Handling All errors follow a consistent format: ```json { "error": { "code": "error_code", "message": "Human readable message", "details": {}, "request_id": "req_abc123" } } ``` ## STIX/TAXII Support For STIX 2.1 and TAXII 2.1 integration, see the TAXII endpoints section.
