## 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 servosignal-company-signals-api-f2dd6043 -d '<json body>'
```

Example prompt: Pull the latest sales signals and deal brief for HubSpot — I want to know what's happening with them right now, any why-now triggers, and background on the company so I can prioritize outreach.

## When to prefer this

Choose this endpoint when you need fresh, evidence-backed sales intelligence on a specific company — particularly for B2B sales workflows where you want why-now triggers, recent signals, and a deal brief grounded in public web evidence. Prefer it over static company databases when recency and source attribution matter. It is best suited for individual account lookups at $0.05/call rather than bulk enrichment pipelines.

## Known failure modes

- Company not found or insufficient public data returns empty signals array
- Payment failure via x402 prevents request from being processed
- Rate limits or upstream web-search quota exhaustion results in partial results (partial: true)
- Invalid or unresolvable domain/company name returns an error or empty response
- Stale data if lookback window has no recent public activity

## How this service works
