Three Ways In

API. CLI. Agent Skill.

Use raw HTTP, a terminal, or hand the whole thing to an AI agent. Same key, same data.

1. The REST API

Plain HTTPS with Bearer keys. JSON in, JSON out, predictable errors and rate-limit headers on every response.

curl
curl "https://api.superx.so/v1/posts?sort=likes&limit=5" \
  -H "Authorization: Bearer sxk_..."

2. The CLI

Fourteen commands covering posts, analytics, contacts, and scheduling. Clean JSON on stdout, so it pipes straight into jq.

terminal
npm install -g superx-cli
superx login
superx posts:analytics --since "2026-06-01T00:00:00Z"
superx scheduled:create --text "Hello from the CLI" --at "2026-08-01T15:00:00Z"

3. The agent skill

One command teaches Claude Code and compatible agents the whole workflow, plus a growth playbook so drafts follow strategy, not vibes.

terminal
npx skills add superx-so/superx-agent

Questions

Frequently Asked Questions

What is the SuperX API?

A REST API for your Twitter/X presence through SuperX: read your published posts and their metrics, pull account analytics over time, list the people who engage with you, and create or delete drafts and scheduled posts. Base URL is https://api.superx.so/v1 with Bearer API key authentication.

Is the API included in my plan?

Yes. Any active SuperX subscription includes API access. Create keys from Account, then Developers in the SuperX app. No separate API pricing.

What are the rate limits?

Per API key: 60 read requests per minute and 10 write requests per minute, with daily caps of 10,000 reads and 300 writes. Every response carries X-RateLimit headers, and over-limit requests return 429 with Retry-After.

What can AI agents do with it?

The superx-agent skill teaches agents like Claude Code to use the SuperX CLI: check your analytics, study your best posts, find who engages with you, and queue drafts or scheduled posts. It ships with a growth playbook so the agent follows a proven strategy instead of posting randomly.

Can my agent use viral post data?

Yes. Your agent can pull viral ideas, topics, and structures from a library of more than 50 million real posts through the SuperX API and CLI, and use them as reference when it drafts. That is how drafts stop sounding like AI and start following what works on X today.

Can the API post immediately or upload media?

Writes create drafts or scheduled posts on your main account, and text or threads up to 25 parts are supported. Media upload is not available in v1 yet. Posts without a scheduled time land as drafts you can review in the app.

Is there an MCP server?

Coming soon. Today the recommended path for agents is the CLI plus the superx-agent skill, which works with Claude Code and other agent tools out of the box.

Where are the docs?

Full documentation lives at docs.superx.so, including the API reference, authentication, rate limits, and the CLI guide. There is also a machine-readable quickstart at GET /v1/docs that needs no authentication.
