How to Migrate from TwitterAPI.io to OmniX (and Cut Tweet Costs 3×)

TwitterAPI.io is a solid product — but if your workload is mostly reads, writes and DMs rather than firehose streaming, you are probably overpaying, and you are definitely missing surfaces it does not have. This guide walks through a real migration to OmniX: what changes, what maps 1:1, and what you gain.

Why teams migrate

• 3× lower tweet costs. TwitterAPI.io advertises $0.15 per 1,000 tweets ($0.18 per 1,000 profiles). OmniX charges a flat $0.001 per call, and a search or timeline call returns ~20 tweets — about $0.05 per 1,000 tweets.
• One price, no rate card. Every OmniX endpoint — search, DMs, posting, articles, follows — costs the same $0.001. Your bill is simply calls × $0.001.
• Encrypted XChat DMs. OmniX reads, sends and decrypts X's end-to-end encrypted DMs. No other API (TwitterAPI.io included) offers any of this.
• Per-call proxy routing. Pass an optional http/https proxy on any request — useful for per-account IP hygiene that a shared scraping pool can't give you.

The one conceptual difference: the account model

TwitterAPI.io is key-only: you send an API key and read public data from their pool. OmniX runs every call as an X account you provide — you pass the account's auth_token cookie alongside your OmniX key. That is what unlocks viewer-relative data (like whether you can DM someone), full write actions, and DMs. For read-only pipelines the change is just one extra field in the request body.

Step 1 — Get a key and make one call

curl "https://api.omnixapi.com/api/v1/twitter/user/info?auth_token=YOUR_X_AUTH_TOKEN&username=nasa" \
  -H "Authorization: Bearer YOUR_OMNIX_KEY"

Sign up for a free key ($0.20 in credits — a few hundred calls) and diff this response against your current TwitterAPI.io payload before touching production code.

Step 2 — Map your endpoints

The shapes are close; most fields map by name. The common mappings:

Job	TwitterAPI.io	OmniX
User profile	user lookup	/twitter/user/info
Tweet search	advanced search	/twitter/search
User tweets	user timeline	/twitter/user/tweets
Followers	followers list	/twitter/user/followers
Post a tweet	create tweet	/twitter/tweet/create
DMs (standard + encrypted)	—	/twitter/dm/*

Every endpoint's docs page shows a live response example, so you can diff shapes field-by-field before writing the adapter.

Step 3 — Move your webhooks

Both services push events over webhooks. On OmniX you create a subscription with filter rules and point it at your existing receiver — the payload is JSON either way, so most teams reuse the same handler with a thin normalizer in front.

Step 4 — Swap the MCP server

If your agents use TwitterAPI.io's MCP server, the OmniX equivalent is one config change:

{
  "mcpServers": {
    "omnix": {
      "command": "npx",
      "args": ["-y", "omnix-mcp@latest"],
      "env": {
        "OMNIX_KEY": "omnix_live_...",
        "X_AUTH_TOKEN": "your_x_auth_token"
      }
    }
  }
}

55 tools, including the encrypted-DM tools no other MCP server has. Full MCP guide here.

When to stay on TwitterAPI.io

Honest note: if your core need is firehose-style WebSocket streaming at 1,000+ QPS sustained, TwitterAPI.io is built for that scale and you should keep it for that pipeline. Plenty of teams run both — bulk streaming there, everything account-shaped (writes, DMs, agents) on OmniX.

Migration checklist

• Get an OmniX key, diff one response against production
• Swap base URL to https://api.omnixapi.com, add auth_token to request bodies
• Map field names in your adapter layer (usually < 1 hour)
• Re-point webhooks, reuse your receiver
• Swap the MCP config if you run agents
• Watch the first invoice drop ~3×
