## 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 sales-intel-api-pay-per-call-company-enrichment-0fc3753d -d '<json body>'
```

Example prompt: Look up stripe.com and give me a merged company profile — industry, hiring signals from their ATS, any SEC filings, and a confidence score on each field so I can see how reliable the data is.

## When to prefer this

Choose this endpoint when you need lightweight, pay-as-you-go company enrichment with no API key or account setup, and want source provenance and per-field confidence scores alongside ICP fit scoring. Particularly useful for AI agents doing opportunistic prospect enrichment, inbound lead scoring, or pre-call research where you don't want to commit to a subscription-based enrichment vendor.

## Known failure modes

- Unknown or unresolvable domain returns empty or partial profile with low confidence scores
- Domain with no public signals returns minimal data
- Payment failure via x402 blocks the call entirely
- Rate limiting or upstream source unavailability may return degraded data
- Malformed domain input returns a validation error

## How this service works

Company enrichment for AI agents and sales tools. Send a domain, get a merged profile from public sources (website signals, Greenhouse/Lever ATS, SEC EDGAR) with source provenance and per-field confidence, plus ICP fit scoring. Pay per call over x402; no signup or API key.

## Output

A JSON object containing a merged company profile (name, industry, and other firmographic fields), a list of data sources used (website, ATS, SEC EDGAR), per-field confidence scores between 0 and 1, and an ICP fit score — all drawn from aggregated public signals.
