Quick wins
Low-cost fixes that would nudge this grade up.
- JSON error bodies for API callers Return a JSON error body (application/json or application/problem+json), not an HTML page, when the caller sends `Accept: application/json`.
- /ai.txt AI-crawler directives Add a short `/ai.txt` at the site root declaring your AI-crawler usage terms (see spawning.ai/ai-txt).
- /llms-full.txt long-form index Add a `/llms-full.txt` — the full-text companion to llms.txt with your key docs inlined for LLMs (see llmstxt.org).
- /llms.txt index for LLMs Add a short `/llms.txt` Markdown index of your key URLs (see https://llmstxt.org).
- /.well-known/agent.json (A2A AgentCard) Publish an A2A AgentCard at `/.well-known/agent.json` with name, description, skills, and endpoints.
Blocking issues

- OpenAPI specification discovery No OpenAPI spec found at any of 9 conventional paths.
- robots.txt AI-agent rules Only 1 of 13 AI user-agents can crawl /; 12 blocked.
- Public MCP registry listing Host bbc.co.uk not listed in any of 2 registry/registries consulted.
