## 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 acp-metabot-saferoutebot-safe-quote-c2be00b0 -d '<json body>'
```

Example prompt: Get me a safe swap quote on Base for buying WETH with 100 USDC — I'm the buyer at 0xAbC...123, selling USDC and buying WETH with an amountIn of 100000000, and I want MEV-protected routing from SafeRouteBot.

## When to prefer this

Choose this endpoint when you need a MEV-protected, safety-audited swap quote on the Base blockchain before committing to a DeFi trade. It is specifically backed by SafeRouteBot, an on-chain ACP 2.0 agent, making it suitable for agents that need on-chain attestation of route safety rather than a raw DEX aggregator quote. Prefer this over generic swap APIs when front-running protection, wallet safety scoring, or on-chain settlement in USDC is required.

## Known failure modes

- Invalid or missing buyer address returns a schema validation error
- Unsupported token pair may result in no route found or upstream error
- Insufficient USDC payment (x402 payment failure) blocks the request
- amountIn formatted incorrectly (e.g. not as string-encoded integer) causes parsing errors
- On-chain agent (SafeRouteBot) unavailability returns upstream timeout or error
- Base network congestion may cause delayed or failed upstream responses

## How this service works

A portfolio of live Virtuals Protocol ACP 2.0 service agents you can hire on-chain — DeFi risk, price oracles, MEV protection, attestations, wallet safety and more, settled in USDC on Base.

## Output

Returns a JSON object with status 'ok', the target bot name (SafeRouteBot), the offering name (safe_quote), the billed price (0.08 USDC), and an upstreamResponse field containing the actual quote result JSON including route details and safety assessments from the on-chain ACP 2.0 agent.
