## 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 base-intel-tokenpulse-on-chain-token-metrics-api-ebf623e6
```

Example prompt: What are the current on-chain pulse metrics for the Base Mainnet token at contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — I want to see price, volume, and liquidity activity right now.

## When to prefer this

Use this endpoint when you need real-time on-chain token metrics specifically for Base Mainnet tokens and want per-request USDC micropayment pricing (no subscription required). Prefer this over general crypto price APIs when you need Base-native on-chain data depth rather than CEX price feeds. Best for agents doing token research, DeFi analysis, or portfolio monitoring on Base.

## Known failure modes

- Invalid or non-existent contract address returns 400 or empty result
- Token contract exists but has no recent on-chain activity — sparse data returned
- Payment not fulfilled (x402 unpaid) — 402 Payment Required response
- Token is on a different chain (not Base Mainnet) — data not found
- Rate limiting or quota exceeded if payment fails
- Network congestion causing stale or delayed on-chain data

## How this service works

4 production x402 APIs on Base Mainnet: AlphaStream, TokenPulse, WalletWatch, RugRadar. Pay per request in USDC or subscribe via Stripe.

## Output

Returns real-time on-chain intelligence for the specified Base Mainnet token, including metrics such as current price, trading volume, liquidity depth, holder activity, and other market pulse signals derived from on-chain data.
