AI coding agents

Integrating through Claude, Cursor, GitHub Copilot or another AI coding agent? Give it the agent docs. They add what the API reference leaves implicit: the rules a correct integration follows, copy-ready client code in Python and TypeScript, and a test plan. Every environment serves them without authentication:

File	Path	Use it for
Index	`/llms.txt`	Agents that discover docs via the llms.txt convention
Full docs	`/llms-full.txt`	One Markdown file: integration guide and API reference
Claude skill	`/agents/e-parcel-api.zip`	Claude Code, Claude.ai, Claude Desktop

Connect your agent

Install the skill in your project (use ~/.claude/skills instead to have it in every project):

curl -fsSL https://api.e-parcel.fi/agents/e-parcel-api.zip -o e-parcel-api.zip
unzip -o e-parcel-api.zip -d .claude/skills && rm e-parcel-api.zip

Start a new claude session. It loads the skill whenever you work on the integration; type /e-parcel-api to load it explicitly. On Windows, use Expand-Archive e-parcel-api.zip -DestinationPath .claude\skills instead of unzip.

Download https://api.e-parcel.fi/agents/e-parcel-api.zip and upload it as a custom skill: Customize → Skills → “+” (on older layouts Settings → Capabilities → Skills → Upload skill). Code execution must be enabled.

Or add https://api.e-parcel.fi/llms-full.txt to a Project’s knowledge instead.

Point the agent at https://api.e-parcel.fi/llms-full.txt, or add this to the AGENTS.md (or equivalent rules file) in your repository:

## E-Parcel shipping API
Before changing E-Parcel integration code, read
https://api.e-parcel.fi/llms-full.txt and follow its golden rules.
Develop and test against https://api-test.e-parcel.fi only.

A good first prompt

Integrate our order fulfilment with the E-Parcel API using the e-parcel-api skill. Target the test environment; the API key is in the EPARCEL_API_KEY environment variable.
