chartavisa (Python)

Thin, dependency-free Python client (standard-library urllib only) for the Charta Visa agent API.

Charta Visa is an independent private service, not a government website. Government fees are stated separately and paid to the authorities in full. Full docs, MCP server and the OpenAPI spec: https://chartavisa.com/developers.

Install

pip install chartavisa

Python 3.8+. No runtime dependencies.

No API key needed

The three helpers below call the public read endpoints: no key, no sign-up, CORS-enabled, 30 requests/minute per IP.

import chartavisa

elig = chartavisa.check_eligibility("IN", "US")
# {'required': True, 'visa_type': 'DS160', 'visa_name': 'US Visitor Visa (B1/B2)',
#  'pricing': {...}, 'links': {'apply_url': ..., 'requirements_url': ...}, ...}

quote = chartavisa.quote_pricing("ESTA", processing_speed="rush", num_travelers=2, currency="eur")
print(quote["charged"])   # {'amount': ..., 'currency': 'EUR', 'fx_rate': ...}

products = chartavisa.list_visa_products()
print([p["id"] for p in products["schemas"]])   # ['ESTA', 'DS160', 'UK_ETA', 'ETIAS', 'CANADA_ETA']

With an API key / other endpoints

from chartavisa import ChartaVisa, ChartaVisaError

cv = ChartaVisa(api_key="cv_agent_…", user_agent_suffix="my-app/1.0")
try:
    me = cv.request("GET", "/api/v1/agent/me")
    status = cv.request("GET", "/api/v1/agent/status/<application_id>")
except ChartaVisaError as e:
    print(e.code, e.status, e.message, e.hint)

request(method, path, body=None) works for every endpoint in the OpenAPI spec; it unwraps the { "success": true, "data": … } envelope and raises ChartaVisaError (with .code, .status, .hint, .details) on any error.
