Do the SEC EDGAR data APIs require an API key?

The SEC states that data.sec.gov RESTful data APIs deliver JSON data and do not require authentication or API keys. Automated access still must comply with SEC fair access policies, including declared User-Agent headers and moderated request rates.

What does DealCharts add for structured finance developers?

DealCharts exposes public facts JSON, entity search, source document links, CSV-style dataset paths, and an ontology for structured-finance entities such as CMBS deals, Auto ABS deals, BDCs, CLOs, funds, CIKs, and counterparties.

What the SEC APIs Give You

The SEC's public developer documentation separates EDGAR data access from filer-submission APIs. For data analysis, the important public surfaces are submissions history and extracted XBRL facts served as JSON on

data.sec.gov

Official SEC data APIs

Public JSON, no data API key

The SEC describes

data.sec.gov

as RESTful JSON APIs for submissions by company and extracted XBRL data. The SEC API page says these data APIs do not require authentication or API keys.

SEC EDGAR API documentation

Fair access

Declared User-Agent and 10 requests per second

SEC guidance asks automated users to declare a User-Agent, download only what they need, and keep request rates within the current 10 requests per second fair-access limit.

Where DealCharts Adds Structure

Raw EDGAR is the source. DealCharts is the read layer for structured-finance context built from those public filings. Use it when the task is not just "fetch a filing," but "connect this filing, CIK, fund, deal, or chart to a citable structured-finance object."

Entity resolution

Move from CIKs to deal and fund pages

Search resolves issuer names, fund names, deal slugs, BDC tickers, and structured-finance entities into stable DealCharts pages and facts paths.

Machine-readable facts

Use facts JSON for agents and scripts

Facts files carry identifiers, dates, source documents, provenance, citation text, and page URLs for downstream research, retrieval, and audit trails.

Data model

Keep ontology and source documents visible

The ontology maps FilingDocument, Deal, Tranche, Fund, Counterparty, Chart, and Dataset objects so your application can distinguish source filings from DealCharts projections.

Human workflow

Route hard questions to CMD+RVL

If you need a custom monitor, bulk pull, or filing-state workflow, CMD+RVL can scope the data path without moving evidence logic into DealCharts.

Structured-Finance Workflows

CIK to filing history
Find the filing universe first
Use SEC submissions JSON for a 10-digit CIK such as
```
CIK0001018724
```
. Then search DealCharts when you need structured-finance exposure, deal pages, or facts JSON tied to that filing entity.
10-D and ABS surveillance
Connect remittance filings to deal objects
Use EDGAR for source filings. Use DealCharts to inspect CMBS and Auto ABS deal pages, chart paths, facts JSON, and source document references for normalized surveillance context.
Fund holdings
Bridge NPORT-P disclosures into fund facts
Fund pages expose NPORT-P-derived holdings context and facts JSON, useful when a model or analyst needs a source-backed answer to who holds a structured-finance position.
AI retrieval
Prefer citable facts over scraped snippets
Retrieval agents can pair
```
llms.txt
```
, facts endpoints, and ontology references with SEC source URLs to ground answers in public filings and stable DealCharts IDs.
