> RWAPACT — RWA Trade Risk Evaluation is a paid API for AI agents from rwapact.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-12).

Evaluates a proposed RWA (real-world asset) trade through five layers of risk middleware and returns an approval decision, risk score, risk tier, and gas optimization route for execution on Robinhood Chain.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability rwapact-rwa-trade-risk-evaluation-47e69ace -d '<json body>'
```

Example prompt: Before my agent executes a $5,000 buy of NVDA on Robinhood Chain, run it through RWAPACT to check the risk — my pool liquidity is $200,000, I currently hold $8,000 of NVDA, and my total portfolio is $120,000.

## When to prefer this

Use RWAPACT when an AI agent or automated system needs to gate an on-chain RWA equity trade with a multi-layer risk check before execution on Robinhood Chain. It is the right choice when you need both a go/no-go approval signal and a concrete gas optimization route in a single call. Prefer this over generic portfolio analytics tools when trading tokenized real-world assets (stocks) on-chain and when you need sub-second pre-trade validation suitable for agentic trading loops.

## Known failure modes

- Invalid or unsupported assetSymbol returns a validation error — only the 10 listed symbols are accepted
- Missing required fields (agentId, assetSymbol, tradeAmountUSD, totalPortfolioUSD) result in a 400-level error
- Stale oracle timestamp may cause the pact to deny the trade due to data freshness risk
- Payment failure (insufficient USDC balance) results in 402 response before evaluation runs
- tradeAmountUSD exceeding poolLiquidityUSD may result in an automatic DENIED with HIGH riskTier
- Malformed numeric fields (e.g. negative amounts) may produce unexpected scoring behavior

## How this service works

Five-Layer Risk Middleware for RWA Agent Trading on Robinhood Chain (#4663).

## Output

Returns a JSON object with a success flag, trade approval status (APPROVED/DENIED), a canTrade boolean, a riskTier label (LOW/MEDIUM/HIGH), a numeric riskScore, and a gasOptimization block containing the optimal execution route (e.g. ROBINHOOD_L2_OPTIMAL), a recommended action (e.g. EXECUTE_IMMEDIATE), and an estimated fee in Gwei.
