Pricing vs official X API
XFlux is a read-focused developer API with built-in account monitors. The official X API is the right choice when you need write access, user-delegated OAuth, or enterprise firehose — but many teams only need public reads and alerts.

| Official X API | XFlux | |
|---|---|---|
| Access | Developer portal + app setup; tiers vary | Instant signup — API key in under a minute |
| Pricing model | Pay-per-use and/or high monthly tiers | Flat monthly plans (API quota + monitors) |
| Starter cost (approx.) | Historically $100+/mo Basic; PPU ~$0.005/read resource | Free: 1,000 calls + 1 monitor. Starter: $19/mo (150,000 calls, 3 monitors) |
| Profiles / timelines / search | Yes | Yes — REST + MCP |
| Account monitors + webhooks | DIY polling, or expensive streaming products | Built-in monitors; live webhooks on Starter+ |
| Filtered / realtime stream | Pro filtered stream often cited ~$5,000/mo | Account-level monitors as a practical alternative |
| Post / like / DM (write) | Yes (with credentials) | No — read & monitor focus |
| MCP for AI agents | Community wrappers using your X keys | Official Registry package @xflux/xflux-mcp-server |
Vs other third-party read APIs
Many third-party proxies also sell cheaper public reads. XFlux differentiates with scheduled account monitors, signed webhooks, live Signals digests, and an MCP server aimed at research and alerting — not just raw lookup endpoints.
When to use the official X API
- You need to post, reply, DM, or manage follows as a user
- You need full-archive search, compliance streams, or enterprise firehose
- You require official partnership / regulated vendor status
When XFlux fits
- Public profile, timeline, and search reads for a product or agent
- KOL / trading / crypto alerts without a $5k streaming tier
- Self-serve pricing from free → Scale without a sales process
