Authentication

Send your key in the X-API-Key header on every request. An Authorization: Bearer header works too, for tools that only set that one. One key covers REST and the MCP server.

curl https://api.vcinfo.io/v1/me \
  -H "X-API-Key: $VCINFO_KEY"

curl https://api.vcinfo.io/v1/me \
  -H "Authorization: Bearer $VCINFO_KEY"

curl "https://api.vcinfo.io/v1/me" \
  -H "X-API-Key: $VCINFO_KEY"

const res = await fetch("https://api.vcinfo.io/v1/me", {
  headers: { "X-API-Key": process.env.VCINFO_KEY },
});
const data = await res.json();

import os, requests

res = requests.get(
    "https://api.vcinfo.io/v1/me",
    headers={"X-API-Key": os.environ["VCINFO_KEY"]},
)
res.raise_for_status()
data = res.json()

Keeping a key safe

• Call the API from your server. A key in browser or mobile code can be read by anyone who opens it.
• We store only a hash of your key, so we cannot show it again.
• Lost or leaked? Create a new key on your account page, then revoke the old one. A revoked key stops at once.
• An account can hold up to 10 named keys, one per app or environment. They all share the account's monthly allowance.
