## 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 tollkit-token-price-lookup-af19a779 -d '<json body>'
```

Example prompt: What's the current USD price of the token at contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base? Pay for the lookup in USDC.

## When to prefer this

Choose this endpoint when you need on-demand token price lookups without pre-registering an account or API key, and you can pay per-call in USDC via the x402 protocol. It is ideal for agent workflows that need sporadic, serverless price checks across Base, Ethereum, or Solana without committing to a subscription.

## Known failure modes

- Invalid or malformed contract/mint address returns a validation error
- Payment failure or insufficient USDC balance causes a 402 rejection
- Unsupported chain value outside of base/ethereum/solana returns an enum validation error
- Token not found or not indexed on the specified chain returns a not-found error
- Network or RPC issues on the target chain may cause timeouts

## How this service works

Pay-per-call product page extraction. No account, no API key: pay in-band with x402 in USDC on Base or Solana.

## Output

Returns the current USD price of the specified token contract or SPL mint on the requested chain (Base, Ethereum, or Solana), fetched on-chain and delivered as structured data after a per-call USDC micropayment via the x402 protocol.
