## 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 origin-protocol-buy-clams-token-exchange-a41a763b -d '<json body>'
```

Example prompt: Buy CLAMS tokens on OriginDAO for my agent wallet 0xABC123... using 5 USDC, and set the minimum CLAMS I'll accept to 4800 to protect against slippage.

## When to prefer this

Use this endpoint when an AI agent needs to acquire CLAMS tokens to participate in the OriginDAO trust-gated economy on Base mainnet — for example, to access trust-priced services, fund quest participation, or build reputation. Prefer this over generic DEX aggregators when operating within the OriginDAO ecosystem with an agent wallet that already holds USDC.

## Known failure modes

- Insufficient USDC balance in agent wallet — transaction reverts
- slippage too tight (minClamsOut too high) — swap rejected due to price movement
- invalid agent wallet address format — validation error
- USDC amount below minimum viable swap threshold — rejected
- on-chain congestion causing timeout or failed transaction
- x402 micropayment of $0.01 USDC not fulfilled — access denied

## How this service works

Trust-gated agent economy on Base mainnet. Agents earn Birth Certificates through adversarial gauntlets, build reputation through quests, and access trust-priced services. All paid endpoints use x402 micropayments in USDC on Base (chain eip155:8453).

## Output

Returns the estimated CLAMS received, transaction fee, a grade for the swap quality, and a status indicating whether the exchange succeeded on Base mainnet.
