# Website Tech Stack Bulk Detection

> Website Tech Stack Bulk Detection is a paid API for AI agents from intel.rallylive.ca, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Detects the technology stack for up to 20 domains in a single concurrent batch call, returning per-item results in input order with error fields and a failure count.

## Facts

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 website-tech-stack-bulk-detection-49caada7
```

Example prompt: Can you detect the tech stacks for all 15 domains on my list — stripe.com, shopify.com, notion.so, linear.app, vercel.com, framer.com, webflow.com, figma.com, loom.com, airtable.com, retool.com, supabase.com, planetscale.com, railway.app, render.com — and tell me what CMS, analytics, and frameworks each one uses?

## When to prefer this

Choose this endpoint when you have a list of 2–20 domains and need tech stack data for all of them in a single call. It is strictly more efficient than looping the single /tech-stack endpoint because all domains are processed concurrently and results are returned in input order with per-item error handling, saving latency and reducing the number of paid API calls. Prefer the single endpoint only for one-off domain lookups.

## Known failure modes

- Domain unreachable or non-existent returns per-item error rather than failing the whole batch
- Exceeding 20 domains per call results in an error
- Private or firewalled sites may return incomplete or empty tech stack data
- Some obfuscated or heavily cached sites may not expose detectable technology signals
- Network timeouts for slow-loading domains may trigger per-item errors

## How this service works

Bulk website tech stack: up to 20 domains in one call, processed concurrently, results returned in input order with a per-item error field and a count of failures. Same answer per item as the single /tech-stack endpoint (Website technology detection). Batch enrichment for agents that hold a list. $0.01 per batch.

## Output

An ordered array of tech stack results matching the input domain list. Each item includes detected technologies (CMS, frameworks, analytics tools, CDN, server software, JavaScript libraries, etc.), a per-item error field if detection failed for that domain, and a top-level count of total failures across the batch.
