## 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 theirstack-technographics-company-tech-stack-lookup-ce048d91 -d '<json body>'
```

Example prompt: Look up the tech stack for stripe.com — show me all technologies with at least medium confidence and tell me how many job posts mention each one.

## When to prefer this

Use this endpoint when you need a structured, confidence-scored inventory of a specific company's technology stack derived from job posting signals. Prefer company_domain as the identifier for unambiguous lookups. Choose this over general web search when you need machine-readable technographic output with temporal metadata (first/last seen) and job-post counts. It complements the sibling firmographics search endpoint, which finds companies; this one profiles a known company's tools.

## Known failure modes

- Company not found in TheirStack database — returns empty result at no charge
- Ambiguous company_name match — prefer company_domain for deterministic lookup
- Missing required identifier — must supply exactly one of company_domain, company_name, or company_linkedin_url
- Invalid LinkedIn URL format — must be a linkedin.com/company/… URL
- Rate limiting or upstream TheirStack API unavailability — transient 5xx error

## How this service works

TheirStack — List the technologies a company uses, each with confidence (low/medium/high), the number of job posts mentioning it, and first/last dates seen. Pass ONE of `company_domain` (preferred), `company_name`, `company_linkedin_url`; optional `keyword_category_slug_or`, `confidence_or`, `min_jobs`, `limit` (rows). Flat vendor cost per company lookup regardless of rows; free upstream when the company isn't found.

## Output

A flat list of technologies the target company uses, each row containing: technology name, confidence tier (low/medium/high), number of job postings that mention it, and the first and last dates that technology was observed. Returns an empty result (free) if the company is not found in TheirStack's database.
