Client Configuration¶

Constructor¶

from tango import TangoClient

client = TangoClient(
    api_key="your-api-key",           # or set TANGO_API_KEY env var
    base_url="https://tango.makegov.com",  # default
    user_agent="my-app/1.0",          # optional custom User-Agent
    extra_headers={"X-Custom": "val"},  # optional additional headers
)

Parameter	Type	Default	Description
`api_key`	`str \\| None`	`None`	API key. Falls back to `TANGO_API_KEY` environment variable.
`base_url`	`str`	`"https://tango.makegov.com"`	Base URL for the Tango API.
`user_agent`	`str \\| None`	`None`	Custom User-Agent string appended to the default.
`extra_headers`	`dict[str, str] \\| None`	`None`	Additional HTTP headers sent with every request.

The client uses httpx under the hood with a 30-second timeout.

Properties¶

`rate_limit_info`¶

Returns rate limit information from the most recent API response.

resp = client.list_contracts(limit=5)
info = client.rate_limit_info

if info:
    print(f"Remaining: {info.remaining}/{info.limit}")
    print(f"Resets in: {info.reset}s")
    print(f"Daily remaining: {info.daily_remaining}/{info.daily_limit}")

The RateLimitInfo object exposes:

Field	Type	Description

print(headers["content-type"])
