A2A Keys Commands

Issue, inspect, and revoke API keys for an A2A agent you host.


Overview

The superqode a2a-keys command group manages the credentials your A2A server accepts from callers. A key is signed rather than stored, so verifying one is a signature check and a clock comparison with no lookup. That matters on a host whose filesystem does not survive a deploy.

See the A2A guide for how the server uses these keys.


One secret, many keys

Two values do different jobs, and mixing them up is the usual cause of a key that looks correct but is rejected.

Value Where it lives How many
SUPERQODE_A2A_KEY_SECRET On the server, never shared One, permanent
sqk_live_... key Handed to a caller One per caller

The secret signs every key your server issues. Changing it invalidates all of them, and a key minted with a different secret fails signature verification.


Commands

superqode a2a-keys secret

Print a new signing secret to set as SUPERQODE_A2A_KEY_SECRET.

superqode a2a-keys secret

Run this once. Set the value on the server that verifies keys and keep it there.

superqode a2a-keys issue

Mint a key for one caller.

superqode a2a-keys issue "Platform Team" --tier standard --days 30
Option Default Description
--tier trial Free-form label recorded in the key
--days 30 How long the key stays valid
--test-key off Mint a sqk_test_ key instead of sqk_live_
--secret $SUPERQODE_A2A_KEY_SECRET Signing secret

The key is shown once and cannot be displayed again. The command also prints the key id, which is what you need to revoke it later.

The tier is recorded on the key and surfaced to the executor, but the server does not currently branch on its value. Treat it as an attribution label.

superqode a2a-keys verify

Check whether a key would be accepted right now.

superqode a2a-keys verify sqk_live_...

Reports the label, tier, key id, and remaining validity, or the reason the key was rejected.

superqode a2a-keys status

Show whether this environment can issue and verify keys.

superqode a2a-keys status

Reports whether a signing secret is configured and how many key ids are revoked.


Revoking a key

Add its key id to SUPERQODE_A2A_REVOKED_KEYS on the server, comma separated. No code change or redeploy of the application is required.

SUPERQODE_A2A_REVOKED_KEYS=<key-id>,<another-key-id>

From the terminal interface

The same group is available as :a2a-keys inside the TUI, defaulting to status.
