SEC API Rust SDK

Bootstrap async Rust client for SEC API.

Representative workflows

• canonical entity resolution and search
• filing lookup, accession reads, and section reads
• all-statements bundle
• offerings, market calendar, and volatility signal utilities
• MCP info discovery

Example

Methods return Result<serde_json::Value, OmniDatastreamError>: HTTP failures, non-2xx API responses (with parsed JSON body when possible), JSON decode errors, and invalid x-api-key header values are surfaced instead of being ignored.

use sec_api_sdk_rust::SecApiClient;

#[tokio::main]
async fn main() {
    let api_key = std::env::var("SECAPI_API_KEY")
        .or_else(|_| std::env::var("OMNI_DATASTREAM_API_KEY"))
        .ok();
    let client = SecApiClient::new(api_key);
    let entity = client.resolve_entity(&[("ticker", "AAPL")]).await.unwrap();
    let filing = client.latest_filing(&[("ticker", "AAPL"), ("form", "10-K")]).await.unwrap();
    let section = client.latest_section("item_1a", &[("ticker", "AAPL"), ("form", "10-K"), ("mode", "compact")]).await.unwrap();
    println!("{} {} {}", entity["name"], filing["id"], section["title"]);
}

OmniDatastreamClient remains available for existing integrations.
