X API v2 (official)
The official developer interface to X (Twitter), covering the full platform. Since early 2026 it runs on a pay-per-use credit model with the free tier eliminated, and full-archive search is gated to expensive high tiers. For archive research it is now a last resort, practical only if you are prepared to pay per request, this site links out to it rather than querying it.
No programmatic check, opens the archive’s own search.
Why it’s useful & how it works
The official X API is the authoritative source for X data, but since early 2026 it runs on a pay-per-use model: reading a post costs $0.005, and the free tier no longer exists. Basic and Pro flat-rate tiers are closed to new subscribers, leaving new developers on pay-per-use only. Full historical search is restricted to high-cost enterprise tiers. Because of this pricing, Echo links you to X's developer portal for reference rather than querying the API directly; it is not practical as the backbone of a free meta-search.
What’s inside
Covers the entire X platform. Full historical search requires an enterprise plan (roughly $42,000 per month). The pay-per-use tier allows up to 2 million post reads per month at $0.005 each, capped there.
