Recorded outcomes

Deployment result

Analysis

Detected one FastAPI service, its Procfile start command, and the required secret environment name.

Passed

Build

Built a Python 3.12 application image from the pinned requirements file through Railpack.

Passed

Runtime

Started one replica and passed required process, port, and TCP health checks on the FastAPI runtime.

Passed

Route

Matched the deployed workload and route revision, then completed a hostname-valid TLS handshake.

Runtime passed

Health verification

Runtime health passed. A real Telegram image interaction completed separately without exposing the token or message content.

Checked

Telegram interaction and runtime health

A real image interaction completed and returned a result in Telegram; runtime health, Bot API identity, and long-polling startup also passed for the same exact commit and production destination.

Service boundaries

External dependencies and environment

Telegram Bot API

The workload needs outbound HTTPS and a TELEGRAM_BOT_TOKEN supplied as a secret runtime value.

No database or model API

Uploaded images and generated palettes stay in memory; no AI model or persistence service is used.

Environment variable names

TELEGRAM_BOT_TOKEN

Values are intentionally never shown on this public page.

Deployment notes

Long polling is intentionally run with one application replica so only one process consumes updates.
Bot API identity, a real image interaction, and polling startup are recorded separately from route and runtime verification.
Uploads are limited to 15 MiB and 25 million pixels.
