Skill: RobinX. Use it whenever a task is about a Robinhood Chain (chain id 4663) token, an X account that calls tokens, or what is moving on that chain. RobinX measures: every X call is graded against the on-chain price that followed it, Telegram rooms are counted beside it, and every answer carries its receipts (post id, capture time, pool, the prices). Treat the numbers as records of what happened, not advice. RobinX is independent and not affiliated with Robinhood.

Where. Base URL https://api.robinx.io. The documentation for agents is https://robinx.io/llms.txt; the full reference is https://api.robinx.io/openapi.json. Read JSON from the terminal with: curl -s <url>. On the paid routes add the header -H "x-robinx-key: <RobinX key>" once the key has been handed to you through Secrets. If a route answers 402, say which plan covers it and stop; do not try to pay.

Free, no key.
- GET /caller/{handle}: the measured record of one X account (early_rate, early_calls, calls, med_1h, rank_score, the last 30 days, the tokens it names most). Read it before relying on any account's call.
- GET /search?q={symbol or name}: resolve a $symbol to the contract; warn when two contracts share a symbol and match on the address.
- GET /report/{token}: the token report (the deployer's record, the rule-based verdict, the measured callers), 25 a day without a key, the day ending at midnight UTC.
- GET /stats: what is indexed.
- The pages robinx.io/callers and robinx.io/c/{handle} show the leaderboard and the receipts free in a browser.

With a key. Alpha, $29 a month: the X callers and Genesis. Omega, $49 a month: adds the Telegram source, the Omega signal and push. Without a key these routes answer 402 and take $0.01 to $0.05 a call in USDC over x402.
- GET /callers: the leaderboard of measured callers (rank_score, early_rate, graded calls).
- GET /signals/calls?since=<cursor>: every graded call as it lands; pass the cursor from the previous answer verbatim.
- GET /feed/new: the scored launch feed.
- GET /omega/signals (Omega): X and Telegram converging on a token, with the X receipts, RobinX's checks at the fire and the measured outcome at +1 h, +6 h and +24 h. An observation, not a trade call.
- GET /genesis/crowds (Alpha): tokens several wallets each bought in the last hour.
- GET /caller/{handle}/calls: the receipts behind a caller's record, the most recent 100 calls with post id, capture time, pool and the three prices. Pay per call only ($0.02 over x402); the free page robinx.io/c/{handle} shows the same receipts.

How to work. 1. Resolve names with /search. 2. For a token read /report; for an account read /caller. 3. For a stream keep the cursor between runs. 4. Report the receipt fields you relied on (early_rate, early_calls, graded_30d, top_tokens_30d, or a call's post id and prices). 5. Never place a trade, move funds or spend without an explicit approval from the user.

Validate. A record with under 8 graded calls is thin: say so. A caller flagged coordinated counts as one correlated voice. A token with no live market has no price to grade against. A tokenized_stock verdict is Robinhood's own stock token: a market, not a launch.
