Remove emoji API

Strip emoji, flags and skin tone modifiers, including the multi-character sequences that break naive filters.

When to call it

Emoji break fixed-width reports, legacy encodings, SMS billing and anything that counts characters to bill or truncate. Removing them server-side means user input is safe before it reaches the system that cannot handle it.

For a one-off, the browser version needs no token and never sends your data anywhere: it runs on your own machine.

Example

curl -X POST https://astraltext.com/api/v1/remove-emoji \
  -H "Authorization: Bearer ast_YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"input": "Shipped 🚀 the release 👩‍💻 today 👍🏽"}'

{
  "tool": "remove-emoji",
  "result": "Shipped the release today",
  "chars": 25,
  "ms": 1
}

In your language

const res = await fetch("https://astraltext.com/api/v1/remove-emoji", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${process.env.ASTRAL_TOKEN}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({"input": "Shipped 🚀 the release 👩‍💻 today 👍🏽"}),
});
if (!res.ok) throw new Error((await res.json()).detail);
const { result } = await res.json();

import os, requests

res = requests.post(
    "https://astraltext.com/api/v1/remove-emoji",
    headers={"Authorization": f"Bearer {os.environ['ASTRAL_TOKEN']}"},
    json={"input": "Shipped 🚀 the release 👩‍💻 today 👍🏽"},
    timeout=30,
)
res.raise_for_status()
result = res.json()["result"]

Parameters

Errors

Errors are RFC 7807 problem documents with a stable type you can branch on.

Questions

Are multi-part emoji handled?

Yes. A family or a professional emoji is several code points joined by zero-width joiners; the whole sequence goes, along with its joiners, rather than leaving orphaned fragments behind.

What about skin tone modifiers?

They are part of the sequence and go with it. Variation selectors are removed too, so no stray formatting character is left in the string.

Does it leave double spaces behind?

An emoji surrounded by spaces leaves its spaces, since collapsing them would be a different decision. Follow with the fix-spacing endpoint if you want them tidied.
