HoodIntel

HoodIntel serves real-time analysis, forecasts and data queries for tokenized real-world assets on Robinhood Chain. There are no accounts, subscriptions or API keys: every request is paid on the spot with an x402 micropayment in USDG, which makes the API directly consumable by autonomous AI agents.

Run a real analysis against live Chainlink prices, right here. This free demo returns signals only — the full AI report is served on paid x402 requests.

A request without payment returns an HTTP 402 challenge describing exactly what to pay. An agent signs a USDG authorization and retries — no gas, no ETH, no human in the loop.

# 1. Ask for an analysis (unpaid → 402 challenge)
curl "https://hoodintel.xyz/api/analyze?asset=NVDA&timeframe=short&detail=high"

# 2. The agent signs an EIP-3009 USDG authorization and retries
#    with the base64 X-PAYMENT header → 200 OK + analysis

# Health check (free)
curl "https://hoodintel.xyz/api/health"

The reference agent client automates the 402 → sign → retry loop end to end.

HoodIntel implements the x402 v1 standard. Payment settles gaslessly in USDG through the VLED facilitator, using an EIP-3009 transferWithAuthorization signature — so a bot with only USDG (and no native gas token) can pay.

GET /api/analyze?asset=NVDA&timeframe=short&detail=high
   │
   ├─ no X-PAYMENT header
   │     → 402 Payment Required
   │       { amount, asset: USDG, payTo, network, maxTimeoutSeconds }
   │
   ├─ client signs EIP-3009 transferWithAuthorization for USDG
   │     (EIP-712 domain name is "Global Dollar")
   │
   ├─ retry with base64 X-PAYMENT header
   │     → facilitator /verify → handler runs → facilitator /settle
   │
   └─ 200 OK + analysis + X-PAYMENT-RESPONSE (on-chain tx hash)

Settlement only runs after the handler succeeds, so a failed analysis never charges the caller.

You pay per request, in USDG, at the moment of the call. No minimums, no monthly bill.

Holders of $HINT will unlock discounted per-query rates — see the token section below.

Every asset is priced from a Chainlink data feed on Robinhood Chain mainnet (8 decimals, 24h heartbeat). Stock feeds idle outside TradFi hours; responses flag a stale price so agents can weight it accordingly.

$HINT is the utility and alignment token of HoodIntel on Robinhood Chain. The API runs and settles in USDG today; $HINT sits on top as the way holders align with — and share in — the platform's growth.

This page is the single source of truth for the $HINT contract address. Always verify it here before trading — ignore any address shared anywhere else.

Ship the working API first, prove real on-chain payment, then build the token economy on top of demonstrated usage — not the other way around.
