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 a JSON object with: `verdict` (e.g. safe/malicious/suspicious), `score` (numeric risk score), `reasons` (array of human-readable explanation strings), `sources` (array of threat intel sources consulted), `disclaimer`, and a `payment` object with asset, payer, amount in atomic units, network, and on-chain transaction hash for the USDC payment.
Example use cases
Phishing link triage for incoming emails
“I got an email with a link to http://secure-bank-update.net — can you check if it's a phishing site and tell me the verdict and risk score before I click?”
User-submitted URL moderation
“A user just submitted https://free-bitcoin-generator.biz to our platform — can you check its safety score and tell me if it should be blocked?”
Vendor domain vetting before integration
“We're about to integrate with a third-party service at https://payments.vendorcorp.io — can you run a reputation check on that domain and give me the reasons and verdict?”
Technical details
Endpoint
POSThttps://agent-exec.448c.org/check/url?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need accountless, pay-per-call URL/domain safety checking with on-chain payment provenance via x402/USDC — ideal for AI agents that cannot maintain persistent API credentials, need audit trails via blockchain transactions, or are operating in trustless environments. Prefer over traditional URL-scanning APIs when zero-setup and micropayment-native access matter more than high-volume throughput.
Side effects
- Invalid or malformed URL input returns an error
- Unreachable or very new domains may have sparse reasons and low-confidence scores
- Payment failure (insufficient USDC balance or x402 negotiation failure) results in HTTP 402 with no result
- Network or sandbox timeout may result in no response
- False negatives possible for newly registered malicious domains not yet indexed by sources
