Telegram Sentiment Analysis - Score Channel Posts at Scale

channel

One public channel's profile card: its title, description, avatar URL, subscriber count as an integer plus Telegram's own label, and whether the handle resolves to a channel, a group or a bot. Charged once per channel per run, and only when the profile actually resolved. A channel whose profile cannot be read costs nothing and returns a free error row instead.

enrichment

One post scored by the built-in analysis layer: sentiment label with a normalised -1..1 score, extracted content keywords, ticker-style tokens such as $BTC or #TAO, wallet and contract-shaped addresses found in the text, whether the post asks a question, the dominant writing system and a word count. This is a lexicon signal built for triage and sorting at volume, not a financial or moderation verdict, and no accuracy figure is claimed for it. Set enrichMessages to false and this event never fires; it is charged only for posts actually scored, and never for free rows.

channel-check

One channel that was actually read but billed no message and no profile: a monitoring re-run where nothing has been posted since your last run, or a channel whose messages were all filtered out. Charged once per channel per run, never on a channel that billed a message or a profile, and never on one that was private, missing or unreachable - those stay free and return an error row. This is what keeps a monitoring schedule honest: a quiet channel costs one check instead of nothing, and a busy one is billed by message as before.
