Documentation for AI agents

This documentation is meant to be read by people and AI agents alike. All content is generated as static HTML and plain Markdown.

Which format to use

Format	Use it when…
Per-page Markdown — e.g. /en/guides/integration-guide.md	You want to hand a single page to an LLM, or paste it into a chat without the HTML noise.
/llms.txt	You want the agent to discover what the site contains first, then decide what to read. It’s the index defined by the llmstxt.org standard.
/llms-full.txt	You want to load all the guides into the context at once.
/llms-small.txt	Same thing, trimmed down for models with a small context window.
OpenAPI 3.1	Your tooling speaks OpenAPI: it’s the source of truth for the API reference (Envelope, Recipients, Fields, Items, Attachments, Folder, Embedding — with schemas and authentication).

Markdown for every page

Every guide page is also published as plain Markdown: just append .md to its path.

https://developers.legaldoc.io/en/guides/integration-guide.md
https://developers.legaldoc.io/en/guides/fea-orquestacion.md

On top of that, each guide has buttons to copy its Markdown to the clipboard, view it raw, or open that page straight in Claude, ChatGPT, or Gemini with the context already loaded.

Pointing an agent at these docs

For an assistant with internet access, the recommended entry point is llms.txt:

Read https://developers.legaldoc.io/llms.txt and then whichever documents you
need from it to help me integrate the Legaldoc.io v2 API.

If it’s going to generate code against the API, give it the OpenAPI specification directly:

Use https://developers.legaldoc.io/openapi/legaldoc-v2.json as the reference
for the Legaldoc.io v2 API and help me implement the signing flow (and
Advanced Electronic Signature if applicable).

Authentication

Any code an agent generates needs to authenticate. Every API request carries the API Key in the Authorization header, with no Bearer prefix:

Authorization: {API_KEY}
Content-Type: application/json

The complete flow is documented in the Integration Guide, and what Advanced Electronic Signature adds in its dedicated chapter.
