How this service works
Cryptographic prompt-safety + URL threat + token contract verification bundle for autonomous AI agent workflows.
Output
Returns a JSON object containing a status field (TRUST or BLOCK), the tool name used, and an agent_continuation object with structured guidance on whether the agent should proceed, along with threat details and attestation verdicts for prompt safety, URL threat level, and token contract integrity.
Example use cases
Pre-execution agent safety gate
“Before my DeFi agent swaps tokens, I need you to run a full security attestation on the incoming prompt, the DEX URL it's about to hit, and the token contract address — block it if anything looks malicious.”
Autonomous workflow injection firewall
“My agent just received a task payload from an external source — can you run it through the attestation bundle to check for prompt injections, URL threats, and any shady contract interactions before it proceeds?”
Token contract trust check before airdrop claim
“I want to claim this airdrop but I'm not sure the contract is safe — run a cryptographic attestation bundle on the contract address and the site URL before I let my agent sign anything.”
Technical details
Endpoint
POSThttps://stealthguard-402.onrender.com/v1/security/attestation-bundle?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an autonomous AI agent needs a bundled, single-call security gate covering prompt injection, URL threats, and token contract verification simultaneously — rather than calling three separate services. Ideal for DeFi agents, agentic workflows interacting with untrusted external inputs, or any pipeline where a combined cryptographic attestation is needed before execution. Prefer over standalone prompt-scrubbers when you also need on-chain contract and URL threat coverage in one atomic result.
Side effects
- Malformed or missing required input fields return a validation error
- Unresolvable URLs or contract addresses may result in incomplete attestation
- Service cold-start on Render may cause elevated latency or timeout on first call
- Payment failure via x402 protocol blocks the request before processing
- Ambiguous or very short prompt inputs may yield low-confidence safety verdicts
