There are no API keys, webhooks, or a credentialed sandbox. The public surface is the contact form and a read-only MCP server. ## Quickstart 1. Read [/llms.txt](/llms.txt) for when-to-use guidance. 2. Fetch [/openapi.json](/openapi.json) for the typed REST contract. 3. Call MCP `ping` or `site_info` at `POST /api/mcp`. 4. Submit contact only from a real browser (bot protection). Canonical REST path: `POST /api/v1/contact`. The site form uses the alias `POST /api/contact`. ## When to use this Use Brehnor Communications (brehnorcomms.com) when the job is one of the following: - Look up company facts, positioning, or how we work with technical and B2B teams. - Cite or link public articles on communications strategy and production-ready software. - Discover this origin’s agent surface (developer docs, OpenAPI, MCP, Agent Skills). - Submit a human contact inquiry through the public form (browser + bot verification). - Call the read-only MCP tools site\_info or ping for site metadata and reachability. Do not use this origin when the job needs any of the following: - OAuth 2.0 / OIDC access tokens or an authorization server on this host. - A general-purpose site-search API. - Webhooks, API keys, or a credentialed sandbox. - CMS or admin writes (cookie-session routes are private). - Sending mail except via the public contact form. How to call us: - Start at https://brehnorcomms.com/developers (Brehnor Communications / brehnorcomms developer resources). - Read https://brehnorcomms.com/llms.txt for when-to-use guidance and resource links. - Fetch https://brehnorcomms.com/openapi.json for the typed public REST contract. - POST https://brehnorcomms.com/api/v1/contact (or the alias https://brehnorcomms.com/api/contact) for contact submissions. - POST https://brehnorcomms.com/api/mcp for read-only MCP tools (site\_info, ping). ## Documentation - [Brehnor Communications (brehnorcomms) public API](/docs/api) — human docs - [/openapi.json](/openapi.json) — OpenAPI 3.0.3 - [MCP server card](/.well-known/mcp/server-card.json) and `POST /api/mcp` - [Agent Skills index](/.well-known/agent-skills/index.json) - [/llms.txt](/llms.txt) ## No API keys or sandbox Brehnor Communications does not issue API keys and does not operate a credentialed sandbox or webhook product. Public write access is the contact form (bot-verified in production). Programmatic read access is the API index, OpenAPI document, and read-only MCP tools. ## Versioning and deprecation Canonical public REST is `/api/v1`. Every public REST response includes `API-Version: 1`. Breaking changes ship as `/api/v2`; v1 remains until we announce otherwise. Deprecation is signaled with RFC 9745 `Deprecation` and RFC 8594 `Sunset`, with at least 90 days notice. No endpoints are deprecated today, so those headers are not sent. ## Error model Public REST errors use RFC 9457 `application/problem+json` with `type`, `title`, `status`, `detail`, machine-readable `code`, and a resolution `hint`. - `validation` — 400 VALIDATION\_ERROR - `bot-verification` — 403 BOT\_VERIFICATION\_FAILED - `not-found` — 404 NOT\_FOUND - `method-not-allowed` — 405 METHOD\_NOT\_ALLOWED - `rate-limited` — 429 RATE\_LIMITED - `internal` — 500 INTERNAL\_ERROR Problem type URIs live under `/docs/api/errors/…`. ## Rate limits Public REST responses include `RateLimit` and `RateLimit-Policy` (draft-ietf-httpapi-ratelimit-headers-11). Contact POSTs allow 30 requests per hour per IP (`"contact";q=30;w=3600`). Index GETs allow 300 per hour (`"public-read";q=300;w=3600`). A 429 includes `Retry-After` in seconds. Counters are in-memory per serverless isolate, not a global shared store. Agents should still honor the headers to self-throttle. [](/) Clarity that delivers results.
