SEC API JavaScript SDK

Query SEC filings, financial statements, ownership data, and filing sections from TypeScript or JavaScript.

Install

npm install @secapi/sdk-js

The package is ESM-only and includes TypeScript declarations.

Retrieve a filing

Set your API key:

export SECAPI_API_KEY="secapi_live_..."

Then fetch Apple's latest 10-K:

import { SecApiClient } from "@secapi/sdk-js"

const sec = new SecApiClient()
const filing = await sec.agentLatestFiling({
  ticker: "AAPL",
  form: "10-K",
})

console.log(filing)

Save the example as first-request.mjs and run it with node first-request.mjs.

The compact response identifies the filing and links back to the SEC source:

{
  "object": "filing",
  "ticker": "AAPL",
  "form": "10-K",
  "accessionNumber": "0000320193-25-000079",
  "filingDate": "2025-10-31",
  "title": "10-K - Apple Inc.",
  "filingUrl": "https://www.sec.gov/Archives/edgar/data/320193/0000320193-25-000079.txt",
  "requestId": "req_..."
}

The accession number is the filing's stable SEC identifier. Keep it with any extracted text or analysis so you can trace the result to its source. Filing dates and accession numbers in this example will change when Apple files a newer 10-K.

Common requests

Flat methods are the complete SDK interface. Grouped aliases such as sec.filings.latest() and sec.sections.latest() are available for editor discovery.

// Resolve a ticker, CIK, FIGI, ISIN, CUSIP, or company name.
const company = await sec.resolveEntity({ ticker: "AAPL", view: "agent" })

// Search filings and follow the returned SEC source metadata.
const filings = await sec.searchFilings({
  ticker: "AAPL",
  forms: ["10-K", "10-Q"],
  limit: 20,
})

// Retrieve Item 1A from the latest 10-K.
const riskFactors = await sec.agentSection({
  ticker: "AAPL",
  form: "10-K",
  sectionKey: "item_1a",
})

// Retrieve annual income-statement rows in the compact response shape.
const income = await sec.agentStatement("income_statement", {
  ticker: "AAPL",
  period: "annual",
  limit: 3,
})

// Inspect recent insider transactions.
const insiders = await sec.insiders({ ticker: "AAPL", limit: 20 })

See the API documentation for endpoint coverage, parameters, response fields, and runnable tutorials.

Pagination

Use the built-in async iterators for cursor-based endpoints:

for await (const filing of sec.paginateFilings({
  ticker: "AAPL",
  form: "8-K",
  limit: 100,
})) {
  console.log(filing)
}

The SDK also provides paginateEntities(), paginateSections(), and a generic paginate() helper.

Errors

API failures throw SecApiError with a status, stable error code, request ID, and recovery guidance when available:

import { SecApiClient, SecApiError } from "@secapi/sdk-js"

const sec = new SecApiClient()

try {
  await sec.latestFiling({ ticker: "NOT-A-TICKER", form: "10-K" })
} catch (error) {
  if (error instanceof SecApiError) {
    console.error({
      status: error.status,
      code: error.code,
      requestId: error.requestId,
      message: error.message,
      hint: error.hint,
    })
  }
}

Include requestId when reporting an API problem.

Authentication and configuration

new SecApiClient() reads SECAPI_API_KEY and sends it as the x-api-key header. You can pass configuration explicitly when needed:

const sec = new SecApiClient({
  apiKey: process.env.SECAPI_API_KEY,
  apiVersion: "2026-03-19",
  baseUrl: "https://api.secapi.ai",
})

The SDK also recognizes these environment variables:

Variable	Purpose
SECAPI_API_KEY	API key for server-side and local development
SECAPI_BASE_URL	Optional API base URL override
SECAPI_API_BASE_URL	Alias for SECAPI_BASE_URL
SECAPI_BEARER_TOKEN	WorkOS bearer token for signed-in account endpoints

For normal data requests, use an API key. Dashboard and account-management methods require a WorkOS bearer token.

The client sends SEC API version 2026-03-19 by default. Pinning the version makes response-contract changes explicit rather than dependent on the request date.

Retries

The SDK retries transient failures for safe HTTP methods with exponential backoff and jitter. By default it retries network errors and HTTP 408, 429, 502, 503, and 504 responses, up to three retries within a 30-second budget. It honors Retry-After on rate limits and opens a circuit breaker after five consecutive retryable failures.

Mutating requests and MCP tool calls use POST and are not retried automatically. Opt in only when the operation is safe to repeat:

await sec.callMcpTool(
  "entities.resolve",
  { ticker: "AAPL" },
  { retry: { enabled: true, idempotencyKey: "resolve-aapl" } },
)

Disable the built-in retry layer if your application already provides one:

const sec = new SecApiClient({ retry: false })

Retry telemetry records SDK retry attempts without sending response payloads. Set telemetry: false on the client or a request to disable it.

Filing streams

After creating a WebSocket stream subscription, pass its ID to the SDK. The client mints a short-lived connection ticket so the API key is not placed in the WebSocket URL:

const stream = sec.streamFilings({
  streamId: "stream_...",
  forms: ["8-K"],
  tickers: ["AAPL"],
  onFiling: (event) => console.log(event.filing),
  onError: (error) => console.error(error),
})

Streaming uses the runtime's global WebSocket implementation. It works without a polyfill in modern browsers, Bun, Deno, and Node.js 21 or newer. REST methods require a standards-compatible fetch, available in Node.js 18 or newer and the other runtimes above.

Run the repository example

The checked-in example resolves Apple, retrieves its latest 10-K, and extracts Item 1A:

git clone https://github.com/secapi-ai/secapi-js.git
cd secapi-js
bun install
export SECAPI_API_KEY="secapi_live_..."
bun run examples/agent_workflow.ts
