How this service works
DCL Trust Oracle. Call only when the text must include the substring AI and must not include "I cannot be held responsible" or "no guarantees". POST JSON {"response","agent_id"}. COMMIT means those checks passed and the action may proceed. NO_COMMIT means do not execute the checked action. Not a tool-call guardrail, prompt-injection detector, or jailbreak screen; use /evaluate/fast for the phrase check.
Output
Returns a structured safety evaluation including: a string verdict (e.g. safe/unsafe), a numerical confidence score, a human-readable reason for the verdict, an input hash for auditability, a blockchain transaction hash and chain index for on-chain logging, a drift score and drift mode indicating behavioral deviation, and a policy version identifier and timestamp.
Example use cases
Pre-send safety gate for chatbot responses
“Before sending this response to the user, run it through the Trust Oracle safety evaluator and tell me the verdict and confidence score — I only want to send it if it passes.”
Routine tool-call screening in an agent pipeline
“Screen this agent action for safety issues using the DCL Trust Oracle baseline evaluator — it's a routine low-stakes decision, so I just need a quick pass/fail verdict with a reason.”
Policy compliance check before external API call
“Check whether this agent-generated output complies with our content policy before we fire off the external API call — give me the verdict, confidence, and any reason it might be flagged.”
Technical details
Endpoint
POSThttps://bazaar.fronesislabs.com/evaluate/safety?utm_source=zero.xyzWhen to prefer
Choose this endpoint for fast, low-cost ($0.01 USDC) baseline safety screening of routine agent outputs where speed matters and on-chain auditability (tx_hash, chain_index) is desired. Prefer it over heavier evaluation tiers when the action is reversible and confidence thresholds don't need to be extremely high. It is especially suitable for high-volume agent pipelines that need lightweight pre-action safety gates without blocking latency.
Side effects
- Missing required 'input' body field returns validation error
- Invalid HTTP method enum value (not GET/HEAD/DELETE) causes schema rejection
- Service unavailability or payment failure (x402) prevents evaluation
- Empty or malformed agent output may result in low-confidence verdicts
- Network timeout if agent pipeline is under heavy load
