secapi-client 0.3.1

Python SDK for SEC API

SEC API Python SDK

Python SDK for SEC API -- SEC filings, financial statements, ownership data, and more.

Installation

pip install secapi-client

Configuration

from secapi_client import SecApiClient

client = SecApiClient(
    api_key="ods_test_...",
    # Optional: override base URL (defaults to https://api.secapi.ai)
    # base_url="http://127.0.0.1:8787",
)

You can also authenticate with a Bearer token:

client = SecApiClient(bearer_token="your-bearer-token")

omni_datastream_py, OmniDatastreamClient, and OmniDatastreamError remain available for existing integrations.

Environment Variables

Variable	Description
SECAPI_API_KEY	Your SEC API key (starts with ods_)
OMNI_DATASTREAM_API_KEY	Legacy fallback for existing integrations

Configuration Options

Parameter	Default	Description
api_key	None	API key authentication
bearer_token	None	Bearer token authentication
base_url	https://api.secapi.ai	API base URL
api_version	2026-03-19	API version header
retry	None	Retry configuration, or False to disable SDK retries
telemetry	None	Retry telemetry configuration, or False to opt out

Reliability

The SDK retries transient failures with exponential backoff and jitter. Defaults:

• Auto-retried by default: GET, HEAD, OPTIONS
• Opt-in required: POST, PUT, PATCH, DELETE, MCP tools/call
• Always retried regardless of method: 429 rate limits, with Retry-After honored
• Retryable failures: network errors, 408, 429, 502, 503, 504
• Never retried: 400, 401, 403, 404, 422
• Backoff: base 200ms, max 5s, max retries 3, total budget 30s
• Circuit breaker: opens after 5 consecutive retryable failures, cools down for 60s

Disable retries globally if you already wrap the SDK with your own retry layer:

client = SecApiClient(
    api_key="ods_test_...",
    retry=False,
)

Per-call overrides are supported:

filing = client.latest_filing(ticker="AAPL", form="10-K", retry=False)

artifact = client.create_artifact(
    {"kind": "audit", "payload": {"ticker": "AAPL"}},
    retry={"enabled": True, "idempotency_key": "artifact-aapl-audit-2026-05-01"},
)

Only opt into retries for mutating requests when the operation is idempotent from your application's point of view. Provide an idempotency key so ambiguous network failures can be correlated safely.

Retry telemetry emits anonymous client_retry_attempt events to SEC API's telemetry project. Set telemetry=False globally or per call to opt out.

Quickstart

import os
from secapi_client import SecApiClient

api_key = os.environ.get("SECAPI_API_KEY") or os.environ["OMNI_DATASTREAM_API_KEY"]
client = SecApiClient(api_key=api_key)

# Resolve a company entity
entity = client.resolve_entity(ticker="AAPL")
print(entity)

# Get the latest 10-K filing
filing = client.latest_filing(ticker="AAPL", form="10-K")
print(filing)

# Extract a specific section
section = client.latest_section(
    section_key="item_1a",
    ticker="AAPL",
    form="10-K",
    mode="compact",
)
print(section)

Common Use Cases

Financial Statements

# XBRL facts
facts = client.facts(ticker="AAPL", tag="Assets", taxonomy="us-gaap", limit=5)

# Full financial statements
statements = client.all_statements(ticker="AAPL", period="annual", limit=3)

Ownership and Institutional Holdings

# Latest 13F filing (institutional holdings)
holdings = client.latest_13f(cik="0001067983", limit=10)

Market Data

# Market calendar
calendar = client.market_calendar(market="XNYS", duration=3)

# Volatility signal
vol = client.volatility_signal(ticker="AAPL")

Offerings and M&A

# IPO and offering filings
offerings = client.offerings(forms="S-1,424B4", limit=3)

Diagnostics

# Artifact summary (data freshness)
summary = client.artifact_summary()

# System observability (requires admin:operator)
operator_client = SecApiClient(api_key=os.environ["OMNI_OPERATOR_API_KEY"])
obs = operator_client.observability()

Error Handling

from secapi_client import SecApiClient, SecApiError

client = SecApiClient(api_key="ods_test_...")

try:
    result = client.resolve_entity(ticker="INVALID")
except SecApiError as e:
    print(f"Status: {e.status}")
    print(f"Payload: {e.payload}")

Scope

The Python SDK covers the full REST surface including:

• Entity resolution and search
• Filing retrieval and section extraction
• XBRL facts and financial statements
• Offerings, market calendar, and volatility signals
• Ownership, insiders, and compensation data
• Institutional holdings (13F)
• Enforcement actions and M&A events
• Artifacts, diagnostics, and observability
• Events, streams, and webhooks

MCP (Model Context Protocol)

MCP tool calls use HTTP POST, so they are not retried on 502/503 by default. Opt in per call only when the tool is read-only or otherwise idempotent:

result = client.mcp(
    {
        "jsonrpc": "2.0",
        "id": "1",
        "method": "tools/call",
        "params": {"name": "entities.resolve", "arguments": {"ticker": "AAPL"}},
    },
    retry={"enabled": True, "idempotency_key": "mcp-entities-resolve-aapl"},
)
