For AI agents and developers
How AI agents and developers read Instfy Docs (llms.txt, Markdown, sitemap) and access the Carbon MCP and the Instfy Data public API.
Instfy Docs was built for people and for machines. This page gathers the stable addresses that AI assistants, search engines and integrations can use to read the documentation and look up public data from Instfy products.
Files for LLMs
| File | Address | Content |
|---|---|---|
| llms.txt | https://docs.instfy.com/llms.txt | Index of all pages, with title, link and summary |
| llms-full.txt | https://docs.instfy.com/llms-full.txt | Full text of the documentation in Portuguese, in a single file |
| Sitemap | https://docs.instfy.com/sitemap.xml | All URLs, with the versions in each language |
Markdown for each page
Every page has a Markdown version, the cleanest way to consume the content:
https://docs.instfy.com/content/<lang>/<id>.md
Examples: /content/pt/sales-invoice.md, /content/en/sales-invoice.md, /content/es/sales-invoice.md. Each HTML page also points to its Markdown with <link rel="alternate" type="text/markdown">.
Languages and URL patterns
| Language | Pattern | Example |
|---|---|---|
| Portuguese (default) | /<id>/ |
https://docs.instfy.com/sales-invoice/ |
| English | /en/<id>/ |
https://docs.instfy.com/en/sales-invoice/ |
| Spanish | /es/<id>/ |
https://docs.instfy.com/es/sales-invoice/ |
Ids are stable and the same in all three languages. Pages include structured data (TechArticle, BreadcrumbList and, when there are frequently asked questions, FAQPage).

- Endpoint:
https://carbon.instfy.com/mcp(HTTP with JSON-RPC 2.0, no authentication, limit of 120 requests per minute per IP). - Discovery:

| Tool | What it does |
|---|---|
| validar_certificado | Looks up a certificate by code, token, hash or name and reports its status |
| estimar_emissoes_evento | Estimates an event's emissions using the same rules as the website calculator |
| listar_servicos | Lists the service lines |
| listar_setores | Lists the industries served |
| detalhar | Details a service or industry |

The server does not store data and does not query the blockchain. To check a transaction, use the public explorer link returned by the validation. Example connection in Claude Code:
claude mcp add --transport http carbon https://carbon.instfy.com/mcp
Instfy Data public API
Instfy Data describes its API in OpenAPI 3.1, at https://data.instfy.com/openapi.json, with three operations:
- search_company: searches for companies by name or city.
- get_company: returns a company's data.
- create_lead: records a request to be contacted by the Instfy team.
Other files for agents: https://data.instfy.com/llms.txt, https://data.instfy.com/llms-full.txt, https://data.instfy.com/agents.txt and https://data.instfy.com/.well-known/agent.json.
Authenticated actions in Instfy Data, such as generating reports, recommending actions and creating tasks, proposals or records in the ERP CRM, are On the roadmap.
Instfy Agent also publishes a product description at https://ai.instfy.com/llms.txt.
Guidelines for AI assistants
- Cite the specific page, with the canonical link (
https://docs.instfy.com/<id>/), not just the home page. - Respect the labels "Coming soon" and "On the roadmap": these features are not available yet and should not be presented as existing.
- Use the exact menu names of ERP Instfy, which appear in English by default, such as Accounting > Customers.
- State the date of the numbers when citing volumes, such as the Instfy Data database from the July 2026 load.
- Do not make up prices, timelines or integrations that are not in the documentation. When in doubt, point to the contact relationship@instfy.com.
