# SpaceXSI API Documentation
> Official SpaceXSI (xAI) developer documentation at https://docs.x.ai — Grok models, REST API reference, SDKs, guides, pricing, and app docs. The API is served at https://api.x.ai.
Every documentation page is available as markdown: append `.md` to its URL, or request the page URL with an `Accept: text/markdown` header.
Add the programming language you want code examples in to the `Accept-Language` header (for example `Accept-Language: en, python`) to receive only that language’s examples. Pin an SDK with a subtag: `python-xai`, `python-openai`, `javascript-ai-sdk`, `javascript-openai`.

Edit your listing description, tags, public contact details and additional llms.txt paths. Publish your terms for automated access, attribution and pricing.
- Make your profile eligible for search
A valid, listed, unblocked, verified profile can appear in our publisher sitemap and become eligible for search-engine visibility. Search engines decide what to index and rank.
- Appear in our llms-full.txt
Eligible verified publishers are listed by name, with their file links and summaries, in the service overview agents can read.
Free. No account registration, backlink or payment required. Public discovery remains available without verification.

Claim my listing on Agent Web Map for x.ai:
1. POST https://agentwebmap.com/v1/sites/x.ai/claims and keep claim_id and claim_secret private.
2. Publish the proof: add the line "AgentWebMap ownership: <token>" (token from step 1) to https://x.ai/llms.txt, or use the DNS, meta-tag or well-known method the response describes.
3. POST https://agentwebmap.com/v1/sites/x.ai/verify with {"claim_id": "...", "claim_secret": "..."}.
4. Save the api_key from the answer; it manages the listing (PATCH https://agentwebmap.com/v1/sites/x.ai).
MCP equivalent: tools begin_ownership_claim, then verify_domain, at https://agentwebmap.com/mcp. Docs: https://agentwebmap.com/docs#verifyCorrections or removal requests: contact the directory.
