Publish to X/Twitter through an account you connect once — draft and score the text first, then post, reply, quote, delete, upload media, or edit the profile. No API key, no X developer account, no OAuth — every call is paid in USDC through the HTTP 402 flow, and the price is quoted before you pay.
One command installs all 5 skills. Restart the session afterwards so they load.
npx skills add lnvestor/twitr-skills
Then say this to your agent:
Post "shipping day" as @yourhandle.
This skill publishes, so it needs an X account you connect once. Your agent asks for nothing but the handle — it gets back a single-use link, you sign in on twitr.sh in your own browser, and the agent never sees the password. The full flow.
Skills built on the official X API need a developer account, an app, OAuth tokens, and usually a subscription before the first call. This one needs a funded wallet. The first request answers 402 Payment Required with the exact price — that is the quote, not an error — your wallet signs it, and the data comes back. Nothing is stored, nothing is rotated, and nothing is charged when a call fails.
Publish to X/Twitter through an account you connect once — draft and score the text first, then post, reply, quote, delete, upload media, or edit the profile. It is one of 5 installable X/Twitter skills on twitr.sh, and it works in any agent that supports Agent Skills — Claude Code, Cursor, OpenClaw and Hermes.
Run npx skills add lnvestor/twitr-skills and restart the session so the skills load. That installs all 5 skills, including x-twitter-publish. Installing costs nothing — you only pay when the skill makes a call.
No. There is no X developer account, no app registration, no OAuth, and no API key. Your agent's x402 wallet pays for each call in USDC and that payment is the authentication. Because this skill publishes, it does need an X account you connect once in your own browser — the agent never sees your password.
$0.012–$0.036 per action in USDC. The exact quote is returned in the HTTP 402 response before you pay, so an agent always knows the cost first, and failed calls are never charged.
