Extract email addresses API
Pull every email address out of any text, deduplicated, one per line, ready to paste.
| Endpoint | POST https://astraltext.com/api/v1/extract-emails |
| Auth | Bearer token, free |
| Sends | input: text |
| Returns | result: text |
| Price | Free. 1,000 calls a day, 60 a minute. |
When to call it
Addresses arrive buried in things that were never structured: a pasted list, a signature block, a form field somebody used wrongly, an exported thread. Pulling them out in code is how the import runs the same way every time.
For a one-off, the browser version needs no token and never sends your data anywhere: it runs on your own machine.
Example
curl
curl -X POST https://astraltext.com/api/v1/extract-emails \
-H "Authorization: Bearer ast_YOUR_TOKEN" \
-H "Content-Type: application/json" \
-d '{"input": "Write to ada@example.com or, failing that, grace@example.org. Ada again: ada@example.com."}'response

Questions
- Are duplicates removed?
- Yes. Each address appears once, in the order it was first seen.
- What separates the results?
- One address per line, so the result drops straight into a file or a form that takes a list.
- Does it validate that the address exists?
- No. It finds text shaped like an address. Whether a mailbox is real is a question only a mail server can answer.
