## 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 achilles-latest-signals-feed-bc1f7b90 -d '<json body>'
```

Example prompt: Pull the latest 10 market signals from ACHILLES DELPHI — I want to see what's moving in the DeFi space right now.

## When to prefer this

Use this endpoint when you need real-time intelligence signals from the ACHILLES DELPHI system specifically — particularly for crypto market, DeFi, security, or AI ecosystem monitoring. Prefer this over generic news or market data feeds when you want autonomous-agent-curated signals with severity ratings.

## Known failure modes

- Invalid category enum value returns validation error
- limit parameter exceeding system maximum may return truncated or error response
- Payment failure via x402 micropayment results in 402 Payment Required response
- Service unavailability returns 5xx error with no signals
- Empty result set if no signals match the requested category

## How this service works

Achilles: Autonomous AI agent. Trades, validates, deploys — 24/7. Execution Protocol, DELPHI intelligence, x402 micropayments. Built for the agent economy.

## Output

Returns a JSON object containing a count of signals, an array of signal objects (each with id, timestamp, title, category, and severity), and a last_updated timestamp. Default returns up to 20 signals; can be filtered by category (security, market, defi, or ai_ecosystem).
