telegram.posts
stable Standard
Latest public posts of a Telegram channel from the web preview (t.me/s): text, time, views, media.
GET /v1/telegram/posts
What you get#
A list of Telegram results in Onekey's unified shape, in data (an array). An empty array is a normal, successful answer and is charged like any other; a source that reports "nothing found" as an error returns a free 404 not_found instead.
Also known as: /telegram/profile/posts on APIs that nest their paths. See Alternatives and equivalents.
What it costs#
- Standard · 1 credit for a fresh fetch, charged only when it succeeds.
- Free when served from cache (0.2 credit for a cached response over 100 KB).
- Free if the request is invalid (never charged) or the source fails or reports not found (refunded).
Parameters#
| Name | Type | Required | Default | What it is | Constraints |
|---|---|---|---|---|---|

}Field mapping#
How this endpoint's source fields become Onekey's unified schema. Fields the source lacks come back as null.
| Source path | Onekey field | Transform |
|---|---|---|
id | content.id | - |
url | content.url | safeUrl |
text | content.text | - |
createdAt | content.createdAt | toIsoDate |
views | engagement.views | toNumber |
author | author.displayName | - |
photoUrl | media.url | safeUrl |
thumbnailUrl | media.thumbnailUrl | safeUrl |
forwardedFrom | ext.forwardedFrom | - |
Caching and freshness#
- Fresh for about 2 minutes. Repeat calls in that window are served from cache and are free.
- Between 2 minutes and 15 minutes the cached copy is still served instantly and marked
stale: truewhile Onekey refreshes it in the background. - If the source is down when a refresh is needed, the last copy can be served for up to 1 hour more (marked stale).
- A "not found" is remembered for 1 minute and is free.
- The cache is shared across all customers, which is what keeps repeat calls cheap.
What can go wrong#
| Status | Code | What to do |
|---|---|---|
| 401 | unauthorized | Check the x-api-key header. |
| 402 | insufficient_credits | Add credits; your balance must cover the price. |
| 404 | not_found | Unknown endpoint path. |
| 422 | invalid_params | Fix the parameters using the table above. Free. |
| 429 | rate_limited | Wait Retry-After seconds, then retry. |
| 502 | upstream_error | The source failed. Refunded; retry with backoff. |
