# Base Onchain Risk & Token Intelligence API

> Base Onchain Risk & Token Intelligence API is a paid API for AI agents from xx402.icu, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Returns a comprehensive DeFi risk intelligence feed for the Base blockchain, including risk-ranked protocol queues, stablecoin safety, yield pool alerts, token safety scores, and incident history.

## Facts

- Endpoint: GET https://xx402.icu/x402/api/base-defi-risk
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-onchain-risk-token-intelligence-api-c91966a8
```

Example prompt: Pull me the current Base DeFi risk feed — show up to 10 protocols, stablecoins, and yield pools — and flag anything in the avoid queue or with active incident history so I know what to stay away from today.

## When to prefer this

Use this endpoint when you need a broad, ranked DeFi risk intelligence overview of the Base blockchain — covering protocols, stablecoins, yield pools, token safety, wallet risk, and live incident alerts — rather than a single-asset lookup or Ethereum mainnet analysis.

## Known failure modes

- Payment not provided or insufficient USDC — returns 402 Payment Required
- limit parameter out of range (must be 3–12) — returns 400 Bad Request
- Upstream onchain data sources unavailable — source_status may indicate degraded feeds
- Rate limiting if too many calls in a short window — returns 429 Too Many Requests
