# SEC Filing Download & CDN API — Fast PDF and Document Retrieval

> Download SEC filing documents at 100+ requests per second from a global CDN. PDF, HTML, and XML filings mirrored from EDGAR with no rate limits. Get started free at secapi.ai/signup.

EDGAR's 10 requests-per-second rate limit makes bulk document retrieval painfully slow. SEC API mirrors every filing document to a global edge CDN, so you can download PDFs, HTML filings, and XML exhibits at 100+ requests per second with sub-100ms latency worldwide.

## Use cases

### AI training data pipelines

Gather large corpora of SEC filings for fine-tuning language models or building retrieval-augmented generation (RAG) systems.

### Document rendering

Serve filing documents to end users from a fast CDN instead of proxying through EDGAR's slow infrastructure.

### Regulatory compliance

Maintain auditable copies of all filings from counterparties or portfolio companies with stable, versioned URLs.
