## API Pattern
DataForSEO uses two methods for most endpoints:
- **Live** (`/live`) - Synchronous, results in same response
- **Task-based** (`/task_post` + `/task_get/$id`) - Async for large requests
Request bodies are always JSON arrays (even for single requests).
## Key Metrics
### Keyword Metrics
- `search_volume` - Monthly search volume
- `competition` - Competition level (0-1)
- `cpc` - Cost per click
- `monthly_searches` - Monthly breakdown array
### Backlink Metrics
- `total_backlinks` - Total backlink count
- `referring_domains` - Unique referring domains
- `domain_rank` - Domain authority score
- `backlinks_spam_score` - Spam score
## When to Use
- Programmatic SERP tracking at scale
- Keyword research with search volume data
- Backlink analysis and monitoring
- On-page SEO audits
- Competitor analysis
## Rate Limits
- Rate limit headers: `X-RateLimit-Limit`, `X-RateLimit-Remaining`
- Backlinks API: 2000 requests/minute, 30 simultaneous
- Varies by endpoint and plan
## Relevant Skills
- seo-audit
- programmatic-seo
