INTEGRATION GUIDE
Integrate FilingSift with JavaScript
Use the built-in fetch API to request a company or iterate opaque comparison cursors. Check HTTP status before reading data, retain verification and evidence fields, and never construct a cursor yourself.
Company request
const response = await fetch("https://api.filingsift.com/api/v1/companies/AAPL");
const body = await response.json();
if (!response.ok) throw new Error(body.error?.message);
console.log(body.data.latestFiling, body.data.events);Production handling
Set a timeout, log X-Request-Id, store ETags for public GET requests, and follow meta.pagination.nextCursor. For private access, load the bearer key from a secret manager or environment variable; never put it in browser code or source control.
Runnable repository examples cover company lookup, cursor pagination, and authenticated account metadata.
Contract references
See the API documentation, OpenAPI specification, and verification methodology. Webhooks and MCP remain unavailable.
