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
Returns confirmation of the created or updated DNS records for the requested subdomain label under 448c.net, including the fully qualified hostname and the records that were set.
Example use cases
Temporary subdomain for agent demo
“Set up a DNS entry for the label 'demo-bot' under 448c.net so I can give my prototype a reachable hostname — pay the $0.50 USDC fee automatically.”
Instant hostname for a sandbox service
“Register the subdomain 'sandbox-api' on 448c.net with an A record pointing to 203.0.113.42 — I don't have an account, just use the x402 payment flow.”
DNS bootstrap for a new deployed agent
“I just deployed a new agent at IP 198.51.100.10 and need a public hostname fast — can you create the label 'relay-node' on 448c.net with the right DNS records?”
Technical details
Endpoint
POSThttps://agent-exec.448c.org/dns?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to quickly provision a DNS subdomain under 448c.net without creating an account or obtaining an API key — ideal for ephemeral agent deployments, demos, or sandboxes that require a public hostname on demand, paid with USDC via x402.
Side effects
- Invalid label format (must match ^[a-z0-9][a-z0-9-]{1,30}$) returns a validation error
- Reserved label names are rejected
- Malformed or empty records array causes a schema validation failure
- Payment failure or insufficient USDC balance results in HTTP 402 with no state change
- Duplicate label conflicts may cause errors if the subdomain is already taken
