API changelog

What changed in the API. New fields and methods are added to v1 without a version change.

18.10.2026 — fixes after review

Posts of a channel deleted or unavailable in MAX are no longer returned (404) — as on the site; a repost source from such a channel comes without our number.
A channel by @handle is the same one the site shows, even when old records share the handle.
A broken cursor, edge dates (9999-12-31) and a reversed period in the post feed return 400 instead of 500 or an empty response.
Addresses ending in .json and the /v1/ root return 404; the /v1/schema/ schema and OPTIONS requests cost no units.
The “API.Max Profi” rate is 20 requests per second, as in the plan (the general 10 per second limit no longer cuts it).
Webhooks: only the organization’s owner or an administrator can change them (403 manager_required); test/ — once a minute, no retries; delivery retries stay within a day; a webhook disabled by staff is re-enabled by support (409 conflict); internationalized domain URLs.
MCP: a channel by @handle in arguments is found; an invalid address value returns error -32602.

Category and territory directories, the channel catalog with filters, a channel card by number or handle, finding a channel by link or MAX ID.
Daily channel statistics and posts of public channels.
/v1/me/ — plan, limits and usage; the balance for the owner’s key.
Plan limits: requests per period (30 days from payment) and per second, request packs.
Webhooks about new posts (from the “API.Max Growth” plan) and the “read and write” key.
An MCP server for AI assistants — https://api.datool.ru/v1/mcp/.
