No feed is fastest on every account, so the honest way to pick a low-latency Twitter/X API is to compare published, measured numbers. As of 5 October 2026, three X feeds publish speed pages: TweetStream (170 ms 7-day median), Xanguard (~200 ms median detection, refreshed hourly) and 1322 (150 to 250 ms typical). Xanguard is the lowest-priced of the three, from $49 a month for 50 accounts against $199 and $250 entry plans, and it puts the timestamps you need to verify latency on every event.
Published latency, compared (checked 5 October 2026)
| Feed | Published figure | What it measures | Live data? | Entry price |
|---|---|---|---|---|
| Xanguard B2B API | ~200 ms median; this week 208 ms median, p95 580 ms, p99 806 ms (7 days to 05 Oct 2026) | X post timestamp to first arrival on a Xanguard server, all paid-plan tweets | Yes, hourly, with JSON | $49/mo, 50 accounts |
| TweetStream | 170 ms 7-day median, p95 352 ms | X post timestamp to first TweetStream server receipt | Yes, rolling 24 h and 7 days | $199/mo, 50 accounts |
| 1322 | 150 to 250 ms typical; about 100 ms on manually provisioned "Ultimate" accounts | From publication; stated as operating averages, not an SLA | Published profile | $250/mo, 100 accounts |
| twitterapi.io stream | "P50 251ms, P90 327ms" (site header); "under 500 ms median delivery, 80% under 1 second" (stream page) | Not stated; low-latency path covers authors with 5,000+ followers | No live page found | $29/mo, 6 accounts |
| Official X API (filtered stream) | No published latency | n/a | No | Pay per use, $0.005 per post read |

How to compare latency claims fairly
- Where does the clock start? The fair start is the creation time X embeds in every tweet ID. A clock that starts later hides time.
- Where does it stop? At the vendor's server or at your client? Server-side figures (Xanguard, TweetStream) leave out the network hop to you. Delivery to Telegram adds roughly 0.3 to 0.4 seconds.
- Median or best case? A single fastest detection says little. Ask for the median, and for p95 and p99, because the slow tail is what costs you on a busy day.
- Which accounts? Some feeds are fastest on a hand-picked or high-follower set. Ask how the account you care about is handled.
- Can you check it yourself? If each event carries the post time and the detection time, your own logs settle the argument.
Verify Xanguard's latency in your own logs
Every Xanguard tweet event carries created_at, the post time X embeds in the tweet ID, in milliseconds. Every non-tweet event (deletions, follows, profile changes) carries event_time, when Xanguard detected it. Subtract created_at from your own receive time and you get our published latency plus your network transit:
ws.onmessage = (e) => {
const m = JSON.parse(e.data);
if (m.op === 0 && m.d.event === 'twitter.post.new') {
const latencyMs = Date.now() - m.d.data.created_at; // post time to your process
console.log(m.d.data.author.handle, latencyMs, 'ms');
}
};Run it for a day next to any other feed on the same accounts. That comparison is worth more than any vendor's table, including ours.
Latency is not the only thing that matters
- Event breadth. Xanguard streams deleted tweets, profile changes, new followers and follow or unfollow events on the same WebSocket as tweets. See the X feed for trading terminals and bots.
- Price per account. $49 for 50 accounts, $229 for 250, $849 for 1,000 on Starter.
- Coverage. If you need Truth Social or news alongside X, TweetStream and 1322 cover them; Xanguard covers X only.
- Fast path rules. Ask whether every account gets the same path. On Xanguard, every paid-plan account gets the same detection speed.

Frequently Asked Questions
Among feeds that publish measured numbers, the lowest medians in October 2026 sit between about 100 and 250 ms from X's post timestamp. TweetStream showed a 170 ms 7-day median on 5 October 2026 (from $199 a month), 1322 states 150 to 250 ms typical (from $250 a month), and Xanguard publishes ~200 ms median detection with p95 and p99, refreshed hourly at xanguard.tech/speed, from $49 a month. The official X API does not publish a latency figure.
Xanguard detects tweets in a median of ~200 ms on paid plans, measured from the creation time X embeds in each tweet ID to the first moment the tweet reaches a Xanguard server. The page xanguard.tech/speed shows the current 24-hour and 7-day median, p90, p95 and p99, refreshed hourly from production traffic.
Check four things: where the clock starts (X's post timestamp or something later), where it stops (the vendor's server or your client), whether the figure is a median or a best case, and whether p95 and p99 are published. Then run two feeds on the same accounts and compare created_at with your own receive time.
X offers a filtered stream on pay-per-use access, limited to 1 connection and 1,000 rules per app, but it does not publish a delivery latency figure. Each post read is billed at $0.005 per X's pricing page (checked 5 October 2026).
Of the feeds that publish speed pages, Xanguard has the lowest entry price: $49 a month for 50 accounts over WebSocket and REST, against $199 for TweetStream's entry plan and $250 for 1322's. twitterapi.io's stream starts at $29 for 6 accounts.
