* docs/development/llms/-_{-llms-full-txt/index.mdx
* docs/development/llms/code-examples/index.mdx – hidden page carrying the
* code-examples snippet, linked from llms.txt
* docs.json – a "For AI Agents" group inside every subsection
* pointing at the two landing pages (idempotent)
*
* Temporary build artifacts are written to llms-out/ and copied into the
* contextual raw assets under public/llms/. llms-out/ itself remains gitignored:
* llms-out/.txt – per-section index (pages + endpoints)
* llms-out/-full.txt – per-section full page content
* llms-out//_{.txt – per-subsection index
* llms-out//_{-full.txt – per-subsection full page content
*
* All links inside llms-out/ files are absolute so copied static assets do
* not depend on their eventual directory depth.
*
* Follows the llms.txt convention: https://llmstxt.org/

const CONSTRAINTS_MD = `## Constraints

- REST authentication: use a server-side Bearer API key for an integration operating its own account; delegated OAuth and other product protocols have separate authentication requirements — see https://developers.telnyx.com/auth.md
- Base URL: https://api.telnyx.com/v2 (REST, JSON request/response)
- Rate limits are enforced per endpoint — see APIs fundamentals under the Fundamentals section
- US A2P messaging requires 10DLC registration; some number purchases require country-specific regulatory documents
- When a product documents Ed25519 webhook signing, verify the signature before trusting the payload; follow the selected product's validation and acknowledgment contract

const FOR_AGENTS_MD = `## For AI agents

- When to use Telnyx: tasks requiring programmable voice or calls, messaging, phone numbers, wireless connectivity, AI inference, or low-latency media
- Agent-readable documentation map: ${BASE_URL}/docs/development/agent-readable-documentation.md
- Clean page Markdown: append \`.md\` to a developers.telnyx.com documentation URL; interactive browser components are excluded and replaced with text fallbacks or canonical data sources
- REST: use the consolidated OpenAPI spec linked below with header \`Authorization: Bearer \`
- Structured API errors: ${BASE_URL}/data/api-errors.json · webhook request payloads and publication selectors: ${BASE_URL}/data/webhook-events.json
- MCP (API actions): connect to https://api.telnyx.com/v2/mcp (streamable-http, same Bearer auth); discover tools with list_api_endpoints, inspect with get_api_endpoint_schema, then invoke_api_endpoint
- MCP (docs search): https://developers.telnyx.com/mcp (no auth)
- Credential walkthrough (auth.md convention): https://developers.telnyx.com/auth.md
- API-key signup: obtain account-owner authorization, then follow the signup runbook (documentation, not an API endpoint) at https://telnyx.com/agent-signup.md. Complete email verification, use the temporary session token to create the API key, and store the key in a secret manager; do not log credentials. Existing accounts can manage keys interactively at https://portal.telnyx.com/#/app/api-keys. Verify with a read-only GET https://api.telnyx.com/v2/phone_numbers using \`Authorization: Bearer \`; revoke or rotate keys through the portal.

Every API request authenticates with a Bearer API key:

\`\`\`bash
curl https://api.telnyx.com/v2/available_phone_numbers \\

\`\`\`

Create a key in the Mission Control Portal (https://portal.telnyx.com) or programmatically via the agent signup flow (https://telnyx.com/agent-signup.md).

## Quickstart examples

Send an SMS:

\`\`\`bash
curl -X POST https://api.telnyx.com/v2/messages \\
-H "Authorization: Bearer $TELNYX_API_KEY" \\
-H "Content-Type: application/json" \\
-d '{"from": "+13125550100", "to": "+13125550101", "text": "Hello from Telnyx"}'
\`\`\`

Chat completion (OpenAI-compatible):

\`\`\`bash
curl -X POST https://api.telnyx.com/v2/ai/chat/completions \\
-H "Authorization: Bearer $TELNYX_API_KEY" \\
-H "Content-Type: application/json" \\
