# Avelto

> The email API for developers who want it to just work.

Avelto is an email API for developers: one request to send, verified domains, a sandbox, webhooks and a full event log.

## Markdown for agents

Every docs page, the home page and the pricing page also serve plain markdown. Either send `Accept: text/markdown` or append `.md` to the path (the home page is `/index.md`). Examples: https://avelto.dev/docs/webhooks.md, https://avelto.dev/pricing.md.

- [The whole site in one file](https://avelto.dev/llms-full.txt): product pages, pricing and every docs page, in reading order.
- [All docs in one file](https://avelto.dev/docs/llms.txt): every docs page concatenated, in sidebar order.
- [Pricing as markdown](https://avelto.dev/pricing.md): every plan, step, overage rate and add-on.
