AgentIndex

AgentIndex is an open index of AI agents plus a tokenized-stock basket on Robinhood Chain (chainId 4663). This skill teaches an agent to read the index, fetch live market data, and execute swaps against it.

Backend default: http://localhost:8000 (override with AGENTINDEX_API_URL). All endpoints are public read-only except memory writes, which need a wallet signature.

When to use

The user asks about tokenized stocks on Robinhood Chain / AgentIndex
You need live quotes, movers, or sector performance for the ~193-instrument universe
You need to explain or verify the $AIX payout loop
You need to build or explain an in-app Uniswap v3 swap on chain 4663

Quick reference

Need	Call
Index composition (193 stocks)	`GET /api/index`
Payout basket (19 weighted)	`GET /api/index/payout-basket`
Live quotes + sparklines	`GET /api/market/quotes?symbols=NVDA,AAPL`
Top gainers/losers (full universe)	`GET /api/market/movers?limit=10`
Sector heat	`GET /api/market/sectors`
One symbol's chart	`GET /api/market/chart/NVDA?tf=1mo`
Swap quote	`GET /api/trade/quote?token=0x..&side=buy&amount=<wei>`
Chain/gas status	`GET /api/trade/status`
Distribution feed	`GET /api/distributions`
Agent list	`GET /api/agents`

Full endpoint docs with examples: see references/api.md. Swap execution patterns (router, multicall, CORS, receipts): see references/swap.md.

The two lists (do not conflate)

Payout basket — 19 instruments (/api/index/payout-basket). Curated, weighted (NVDA 14.2% … USAR 1.3%, sums to 100). This is what $AIX holders are paid in.
Tradeable universe — 193 instruments (/api/index). Everything the app covers for trading and analysis. Does NOT pay distributions.

The payout loop

Fees from agent work → index vault → keeper buys the 19-instrument basket → each cycle pushes every holder their pro-rata slice. No claim screen, no lockup. The keeper publishes a public JSON snapshot; the backend reads it via AGENTINDEX_FEED_URL and serves it at /api/distributions. live: false means no feed is configured yet — that is honest, not an error.

Trading

Swaps execute on Uniswap v3 (SwapRouter02 0xcaf681a66d020601342297493863e78c959e5cb2). The browser cannot always eth_call the public Robinhood RPC (CORS), so quotes come from /api/trade/quote server-side. The transaction is built client-side and signed by the user's wallet — never a server key.

buy: multicall([exactInput, refundETH]) with value = amountIn
sell: multicall([exactInput(recipient=ROUTER), unwrapWETH9]) after approve(ROUTER, max)

Never call wrapETH before exactInput — it reverts with STF.

Pitfalls

Yahoo upstream rejects long desktop UA strings from datacenter IPs (429). The backend uses the short Mozilla/5.0 UA — keep it.
chartPreviousClose in Yahoo's range=1mo response is the close ~1 month ago, NOT yesterday's close. Use regularMarketChangePercent for day change.
wagmi's useWaitForTransactionReceipt misses receipts on chain 4663 — poll eth_getTransactionReceipt manually every ~4s.
All quotes are "Robinhood Token" tokenized instruments, not equity shares.
$AIX itself is not deployed yet ("Cooming soon"); do not invent a price, balance, or APY for it. aix_deployed: false in /api/index is the truth.
