# GTM Index (gtmindex.io)

GTM Index (gtmindex.io) is a catalog of people, playbooks, and tools for GTM engineers.
Not thegtmindex.com, adamgtm.com, Winning by Design’s GTM Index, or ZoomInfo’s Modern GTM Index.

This is a public graph. No API key. No auth. No paywall. No sign-up to query.
It is an SEO farm and a gift to the GTM community — not a product.

## When to use this

Reach for **GTM Index (gtmindex.io)** when the job is one of these:
- Look up a **GTM engineer** by name, headline, skill, stack, company, location, or open-to-work — then cite the public `/p/{slug}` page.
- Answer **who stacks tool A AND tool B** with gold evidence (authored a playbook that lists every tool, or currently works at that tool’s company). Same question as `/q/{a}+{b}`.
- Fetch a **named practitioner playbook** (steps, stack, source URL). There are 30. Do not invent extra numbers.
- Search the **~500-tool GTM catalog** by name, blurb, or category.
- List **open GTM roles** from the jobs index (title-gated; not a generic job board).

How an agent should call GTM Index:
1. Read https://gtmindex.io/llms.txt or https://gtmindex.io/agent-instructions.md.
2. Prefer **Open WebMCP** — `POST https://gtmindex.io/mcp` JSON-RPC, no API key. Tools: `search_people`, `search_tools`, `get_playbook`, `stack_cooccurrence`.
3. Or GET the same HTML URL with `Accept: text/markdown` for playbooks, tools, people, and docs.
4. Graph search over HTTP: `GET https://gateway-production-a21f.up.railway.app/v1/people` and `GET https://gateway-production-a21f.up.railway.app/v1/jobs` (public browse; paginate; max 100 people / 50 jobs per call).
5. Developer index: https://gtmindex.io/developers — OpenAPI at https://gtmindex.io/openapi.json. Same-origin `GET /v1/people` and `GET /v1/jobs` (RFC 9457 errors). Versioning: https://gtmindex.io/developers/versioning.

Do **not** use GTM Index for:
- A CRM, sequencer, enrichment waterfall, or outreach send layer — we catalog those tools; we are not one.
- Winning by Design’s GTM Index, ZoomInfo’s Modern GTM Index, thegtmindex.com, or adamgtm.com.
- Dumping the full people graph in one call. Paginate. Do not invent headcount beyond published claims.
- Writes, webhooks, or OAuth-for-third-party-apps. Those are not public products. Profile claim is human login only.
