# BlackSwan Risk Intelligence API

> BlackSwan Risk Intelligence API is a free API for AI agents from x402.blackswan.wtf, Free, status unknown (last checked 2026-09-15).

Provides real-time risk intelligence signals and market state synthesis for AI agents via a discovery endpoint

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 blackswan-82f2e4cb
```

Example prompt: What's the current risk environment looking like — are there any early precursor signals or black swan indicators I should know about right now across major markets?

## When to prefer this

Use BlackSwan when you need real-time tail risk and black swan precursor detection specifically — particularly when you want to catch risk signals before events materialize rather than after. Prefer this over general market data APIs when the use case is early warning intelligence and systemic risk synthesis.

## Known failure modes

- Endpoint returns minimal metadata as it is a .well-known discovery endpoint rather than a full data API
- Service may return 402 Payment Required if downstream endpoints require payment
- Insufficient schema information may result in incomplete risk profiles
- Rate limiting or availability issues on the live intelligence feed

## How this service works

Real-time risk intelligence for AI agents

## Output

Real-time risk intelligence data including precursor detection signals, synthesized market state from multiple data sources, and risk indicators surfaced before events materialize
