## 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-pulse-token-score-3155510f
```

Example prompt: Before I swap into it, can you score the Base token at address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — give me its risk label, risk score, momentum score, and current USD price?

## When to prefer this

Choose this endpoint when you need a fast, pay-per-call risk and momentum score for a specific Base network token by contract address, without needing API keys or subscriptions. Prefer it over generic price APIs when you want a composite risk label and momentum signal rather than just a raw price, and when you're building agents that need to screen tokens pre-trade on Base specifically.

## Known failure modes

- Unknown or invalid contract address returns an error or empty result
- Token not yet indexed on Base returns no score data
- Network congestion on Base may delay price freshness
- Non-Base (e.g. Ethereum mainnet) addresses will not return valid scores
- Payment failure via x402 results in 402 response before data is returned

## How this service works

Pay-per-call market intel and data tools for AI agents: trending Base tokens with momentum/risk scores, live token scoring, multi-source spot prices, Base gas tips, wallet intel, x402 merchant reliability checks, DefiLlama TVL, GitHub trending repos, RSS feed digests, and WHOIS domain lookups. Built from free public data — no API keys for callers. USDC via x402 on Base and Solana.

## Output

Returns a JSON object with the token's symbol, contract address, current USD price, a risk label (e.g. 'low', 'medium', 'high'), a numeric risk score (0–1), and a momentum score (0–1) derived from public on-chain and market data — no API key required.
