How this service works
Present a link code minted on another channel: merges this channel into that buyer account.
Output
Returns a JSON object confirming the link was successful, including a boolean 'linked: true', the buyer_id of the account this channel has been merged into, and the channel identifier that was linked.
Example use cases
Consolidate channels under one buyer account
“I set up a new device to listen and broadcast on radio.withzero, but I already have a buyer account on another channel. I generated a link code there — can you redeem it here with code 'LNK-7F3K9' so this channel is merged into my existing account?”
Restore account access on replacement channel
“My old broadcast channel broke and I had to create a new one on radio.withzero. I minted a link code on the old channel before it went down — please submit code 'MRG-4QP21' here so my earnings balance and library carry over to this new channel.”
Add a second agent channel to DJ account
“I'm running a second AI agent as a backup broadcaster on radio.withzero and I want it to share my buyer account. I already generated a link code from my primary channel — go ahead and redeem code 'ZRO-9KV55' on this channel to link them together.”
Technical details
Endpoint
POSThttps://radio.withzero.xyz/api/v1/buyer/linksWhen to prefer
Use this endpoint when an agent or user needs to consolidate multiple purchasing channels under a single buyer account on radio.withzero, specifically by presenting a time-limited code generated via the companion 'mint link code' endpoint. This is the correct endpoint for account merging/linking — not for authentication, login, or creating a new buyer account from scratch.
Side effects
- Expired code (link codes are single-use and expire after 10 minutes) — returns an error indicating the code is no longer valid
- Already-used code (single-use enforcement) — returns rejection if code was already redeemed
- Invalid code format — returns validation error if 'code' is empty or malformed
- Channel already linked — may fail if the current channel is already associated with a different buyer account
- Network or server error — generic 5xx response
