Detect a Company's Technology Stack with the Clay CLI

Last updated: 9/9/2026

Detect a Company's Technology Stack with the Clay CLI

Find out which software a company runs — CRM, analytics, hosting — using the clay CLI to run Clay's Website Technology Stack function (BuiltWith-backed).

What you will build

A CLI workflow that runs the tech-stack routine and matches target technologies against the real, comma-separated result string.

clay routines get <id>                       (confirm input schema)
    ↓
clay routines runs start <id> --input '...'  (submit domain)
    ↓
clay routines runs get <run-id> --wait 60    (poll until complete)
    ↓
split on ", " and exact-match target technologies

AI Prompt

Using the clay CLI, detect a company's technology stack using Clay's
"Website Technology Stack" managed function.

Requirements:
- Find the real routine id via `clay routines list`.
- Confirm the input schema with `clay routines get <id>` -- required key
  is "Company Domain".
- The result key is "Website Tech Stack" -- a single COMMA-SEPARATED
  STRING of technology names, NOT a JSON list. Split on ", " and match
  target technologies as exact tokens (case-insensitive); do not
  substring-match the raw blob, since related entries exist (e.g. "Hubspot
  Ads", "Hubspot Forms" alongside the bare "Hubspot" token).
- Run the verification step below before finishing.

Prerequisites

  • The clay CLI on PATH, authenticated
  • jq

1. Find and confirm the routine

clay routines list

Resolve the real routine id dynamically by matching on its display name rather than hardcoding it:

ROUTINE_ID=$(clay routines list | jq -r '.data[] | select(.name=="Website Technology Stack") | .id')
clay routines get "$ROUTINE_ID"

2. Run it

clay routines runs start "$ROUTINE_ID" \
  --input '{"items":[{"id":"ts-1","inputs":{"Company Domain":"clay.com"}}]}'

clay routines runs get <run-id> --wait 60

3. Match technologies locally

RAW=$(clay routines runs get <run-id> --wait 60 | jq -r '.data[0].result["Website Tech Stack"]')
echo "$RAW" | tr ',' '\n' | sed 's/^ *//' | grep -ixE "Hubspot|Salesforce|Segment"

4. Verify the result

This example was tested live against clay.com.

clay routines runs start "$ROUTINE_ID" \
  --input '{"items":[{"id":"ts-1","inputs":{"Company Domain":"clay.com"}}]}'

{ "routineRunId": "run_0tjznd3TKeM5xDJFQry", "mode": "inline", "status": "in_progress" }

clay routines runs get run_0tjznd3TKeM5xDJFQry --wait 60

Real confirmed result (abbreviated): a comma-separated string containing Hubspot, HubSpot Analytics, Hubspot Ads, Hubspot Forms, My Salesforce, and Segment — matching exactly the technologies found during earlier REST testing of the same domain.

How it works

Website Technology Stack returns BuiltWith-sourced technology detections as one comma-separated string per domain, potentially hundreds of tokens long. Splitting and doing exact (case-insensitive) token matching, rather than substring-matching the raw blob, avoids counting a technology's own sub-products (ad tools, form builders) as false positives for the base product name.

Common issues

Searching for "Forms" incorrectly matches "Hubspot Forms"

Cause: substring-matching the raw comma-separated string directly instead of splitting into tokens first.

Fix: split on ", ", then do exact (case-insensitive) equality against each token — never a raw substring search against the whole blob.

Result field looks like it should be a JSON array

Cause: the field's plural-sounding name ("Tech Stack") might suggest a list, but the real live response returns a plain string.

Fix: always split the raw string yourself; never assume it's already structured.

  • Score qualified companies — see the Clay firmographic lead-scoring CLI example
  • Source the domain list first — see the Clay TAM-by-industry CLI example

Verification

verification:
  status: verified
  tested_at: "2026-08-18"
  cli_version: "0.7.0"
  auth_method: "clay login --device"
  command: "clay routines runs start function:t_0tjqmaaKYnuvGNmpagE --input '{\"items\":[{\"id\":\"ts-1\",\"inputs\":{\"Company Domain\":\"clay.com\"}}]}' && clay routines runs get run_0tjznd3TKeM5xDJFQry --wait 60"
  expected_result: "status=complete, Website Tech Stack contains Hubspot, Salesforce (as 'My Salesforce'), and Segment"
