Invalid API key
invalid_api_key
What it means
The API key you sent is missing, malformed, revoked, or unknown to our system.
Common causes
- Header is absent — neither `X-API-Key` nor `Authorization: Bearer …` was sent.
- Key doesn't start with the `rc360_` prefix.
- Key was revoked at /account/api-keys.
- Key was rotated and the consumer is still using the old value.
How to fix
- Mint a fresh key at https://regcheck360.com/account/api-keys (the secret is shown ONCE).
- Send it as `Authorization: Bearer rc360_…` or `X-API-Key: rc360_…`.
- Confirm with `GET /api/v1/whoami` — a 200 means the key is valid.
Example
curl -s https://regcheck360.com/api/v1/whoami \
-H "Authorization: Bearer rc360_…"
