epovest

The official Python SDK for the Epovest API.

Epovest is an AI visibility platform: it measures how AI assistants such as ChatGPT, Claude, Gemini, Perplexity, Mistral and Grok answer the questions your market asks (which names they cite, with which sources, how that changes over time), and gives you the levers to shape those answers.

The whole REST API v1 is here, one method per route, generated from the OpenAPI 3.1 description the API serves at epovest.com/docs/openapi.json.

• Synchronous and asynchronous clients, on httpx.
• Typed: every named object of the API is a TypedDict, and every method says what it answers.
• Query parameters are spelled out as keyword arguments, so your editor lists them.

Install

pip install epovest

Python 3.11 and above.

Quickstart

import os

from epovest import Epovest

epovest = Epovest(api_key=os.environ["EPOVEST_API_KEY"])

# What is already measured
trackers = epovest.list_trackers()["trackers"]

# Set up a new measurement, and start it
tracker = epovest.create_tracker(
    body={
        "title": "Market watch",
        "prompts": ["Which GEO tracking solution should I choose?"],
        "engines": ["chatgpt", "claude"],
        "frequency": "weekly",
        "resolution": "hd",
        "keywords": [{"keyword": "Epovest", "favorite": True}],
        "analysts": ["keyword_presence", "share_of_voice"],
    }
)["tracker"]

epovest.start_tracker(tracker["id"])

# Read the series
scores = epovest.get_results(tracker["id"], analyst="keyword_presence")["scores"]

Asynchronous, same names:

from epovest import AsyncEpovest

async with AsyncEpovest(api_key=os.environ["EPOVEST_API_KEY"]) as epovest:
    answers = await epovest.get_responses(tracker_id, engine="claude", tone="negative")

Authentication

Every call carries an API key of your account. The owner creates one in the app, at /account/api-keys; the secret starts with epo_ and is shown once, at creation.

Scopes are chosen at creation: read, which every key has, and write, for creating and changing things. Each method names the scope it takes in its docstring.

epovest = Epovest(
    api_key=os.environ["EPOVEST_API_KEY"],
    timeout=30.0,
    max_retries=2,
    headers={"User-Agent": "acme-reporting/2.1"},
)

The client holds a connection pool: use it as a context manager, or call close() (aclose() on the asynchronous one) when you are done.

What you can call

70 methods, named after the operation they wrap, and the name is the same one the MCP tool carries:

Path parameters come first, the query parameters follow as keyword arguments, and a request body goes in body:

epovest.update_surface(surface_id, body={"languages": ["en", "pt-br"]})
epovest.list_sources(domain="wikipedia.org", sort="aa_claude", per_page=100)

Types

Every named object of the API is exported as a TypedDict, and every method is annotated with what it answers:

from epovest import Credits, Tracker


def shortfall(credits: Credits) -> int:
    return max(0, credits["min_topup_minor"] - credits["available_minor"])

Pagination

GET /sources, GET /trackers/{id}/responses and GET /usage are paginated, and page is clamped: asking for page 99 of 3 answers page 3. paginate reads that the way the API intends, and stops on the last page:

for page in epovest.paginate(lambda page: epovest.list_sources(page=page, per_page=100)):
    for source in page["sources"]:
        print(source["domain"], source["engines"])

Errors

A refused call raises an EpovestError carrying the slug of the refusal. Branch on code, which is stable, rather than on the message, which is written for a person. Everything the envelope carries next to the two of the envelope stays readable in body:

from epovest import EpovestError

try:
    epovest.start_tracker(tracker_id)
except EpovestError as error:
    if error.code == "insufficient_credits":
        # The answer carries what a survey costs, what is available, and where to top up.
        print(error.body["cost_per_survey_minor"], error.body["available_minor"], error.body["top_up_url"])
    raise

A request that never reached Epovest raises an EpovestConnectionError, whose cause carries what the platform reported.

Retries. A 429 rate_limited is sent again whatever the verb, after the wait the Retry-After header names: the budget refuses the call before it runs. A network failure or a 5xx is sent again on reads alone, so a write that may have landed is yours to replay, when you decide it should be. max_retries sets how many times, and 0 turns it off.

Also available as MCP

The same surface is served as MCP tools at https://mcp.epovest.com/mcp, for agents that speak the Model Context Protocol: one tool per route, the same keys and the same error envelopes, and the tool names are the method names of this SDK. See epovest.com/docs/api.md.
