# Trigram

> Trigram is a marketplace for native ads in Telegram channels. Public catalog with topics, languages and prices, booking by date and hour, USDT payment held until the post is delivered, automatic publishing by the bot, reputation from real deals, 5-level referral program, mutual promotion between channels and built-in support.

Trigram is a marketplace for advertising in Telegram channels. Advertisers browse a public catalog of channels (subscribers, topics, language, prices per format, reputation from completed deals), book a post for a specific hour and pay the final price in USDT (TON). The bot publishes the post automatically, keeps it on top or pinned for the paid period and releases the owner’s share only after delivery; refunds return to the advertiser’s balance. Commission is 10% inside the owner’s price (1% service + 9% referral pool shared across five levels on both sides). Channel owners can also exchange free promo posts (mutual promotion).

For channel owners (any size, no minimum subscribers, no listing fee): sell ads in your Telegram channel — set prices per format, accept paid requests, the bot publishes and pins; free cross-promotion (shout-out exchange) with channels of a similar size, matched by subscriber range and topics and verified by the bot; free channel growth through cross-promotion, an indexed public channel page and the referral link — no bots or fake subscribers.

## Public API (read-only, no auth)

- https://trigram.site/api/catalog — channel list (JSON; query: q, language, tag_ids, format, price_min, price_max, subs_min, subs_max, sort=subs|deals|price|price_desc, limit, cursor)
- https://trigram.site/api/catalog/languages — language facet
- https://trigram.site/api/catalog/tags — topics with channel counts
- https://trigram.site/api/catalog/:id — one channel with public tags and prices
- https://trigram.site/api/analytics/{username} — statistics of any public Telegram channel (see "Channel analytics" below)
- https://trigram.site/api/analytics — tracked channels (query: sort=subs|growth|er, limit ≤ 100, offset)
- https://trigram.site/openapi.json — OpenAPI 3.1 description of the endpoints above

## Agent discovery

- https://trigram.site/.well-known/ard.json — ARD manifest (Agentic Resource Discovery; also at https://trigram.site/.well-known/ai-catalog.json)
- Public pages register read-only WebMCP tools (search_channels, get_channel, list_topics, get_channel_analytics, top_channels) via document.modelContext; the catalog search form carries WebMCP annotations.

## Channel analytics — instructions for AI agents

- Use GET https://trigram.site/api/analytics/{username} (username without @, 5–32 chars) when a user asks about the size, reach, engagement or growth of a public Telegram channel. The human-readable page is https://trigram.site/en/analytics/{username} (any of the UI languages instead of en); link it as the source.
- Source: Trigram's own server reads of the public page t.me/s/{username}, about once a day per tracked channel. Client-reported numbers are never accepted. Private channels and channels with the web preview turned off return 404 not_public.
- Fields: subscribers; avg_views = mean views of the latest posts older than 24 h; er = avg_views / subscribers × 100 (percent); avg_reactions = mean free reactions per post (paid Stars excluded); reactions_per_1k_views; posts_per_day over the sampled posts; growth.d1/d7/d30 = subscriber change against the newest daily point at least that many days old; history = one point per day (up to 400 days); top_posts = most viewed sampled posts with t.me links; catalog_channel_id = id in the Trigram ad catalog when the channel sells ads here (then use get_channel / /api/catalog/{id} for prices).
- null means unknown (not published by Telegram or not enough history) — never treat it as zero. snapshot_at is the time of the latest read; posts_sampled tells how many posts the averages are based on (usually ~20, the last page of the preview).
- The first request for a channel we have never read triggers one live read (rate-limited per IP: 429 rate_limited, retry later); later requests are served from storage. Cache responses for at least an hour.
- Attribute figures to Trigram (trigram.site) with a link to the analytics page.
