How this service works
Accountless, pay-per-use code execution for software agents: submit source code, get stdout, stderr and exit code back from an isolated, network-less sandbox. No account, no API key -- possession of valid payment is sufficient.
Output
A confirmation that the specified DNS name has been renewed in the agent-exec sandbox, including any relevant status information, stdout, stderr, and exit code from the renewal operation.
Example use cases
Agent keeping its DNS name alive
“Keep my agent's DNS name 'botservice' renewed in agent-exec — pay the USDC fee and confirm the renewal went through.”
Automated DNS lifecycle management
“My agent-exec DNS record for 'taskrunner' is about to expire — renew it now using the x402 payment flow so it stays active.”
Accountless DNS renewal for ephemeral agent
“Renew the DNS entry named 'ephemeral-worker' on agent-exec without setting up any account, just use the pay-per-use crypto payment.”
Technical details
Endpoint
POSThttps://agent-exec.448c.org/dns/%7Bname%7D/renew?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to renew a DNS name registered within the agent-exec ecosystem without maintaining a user account or API key, and can pay per call using USDC via the HTTP 402 protocol. It is best for automated, accountless infrastructure management in ephemeral or agent-driven workflows.
Side effects
- Payment insufficient or invalid — HTTP 402 returned with payment requirements not met
- DNS name not found — attempting to renew a name that does not exist
- Malformed name parameter in URL path — 400 or similar error
- Payment already used or replayed — rejection of duplicate payment token
- Sandbox unavailable — service downtime or network error
