How this service works
Comprehensive trust assessment for AI agents — reputation score, tier, recommendation, and full breakdown from the Orac Knowledge Graph
Output
A JSON object containing: the entity's trust score (0-1 float), trust tier (e.g. 'new', 'established'), recommendation (e.g. 'CAUTION', 'TRUSTED'), rank position out of total indexed agents, a breakdown of scoring factors (pagerank, age, safety, relations, attestations, observation density), the entity's trust network (who it trusts and who trusts it), and whether the entity was found in the index.
Example use cases
Vet agent before payment delegation
“I want to send a payment through an agent called 'PayBot-7', but before I do, can you check its trust score and recommendation in the Orac Knowledge Graph? I need to know if it's established and safe to handle my funds.”
Compare agent reputations for task
“I have two agents I'm considering for handling sensitive customer data — 'DataSift' and 'VaultAgent'. Can you pull up the trust tier and breakdown for both from the Orac Knowledge Graph so I can decide which one is safer to use?”
Screen new agent before onboarding
“We're about to onboard a third-party agent called 'NexaBot' into our workflow, but I want to make sure it has a solid reputation first. Can you look it up in the Orac Knowledge Graph and tell me its trust score, rank, and whether it comes back as trusted or a caution?”
Technical details
Endpoint
POSThttps://orac-trust.orac.workers.dev/v1/scoreWhen to prefer
Use this endpoint when an AI agent needs to vet another agent, service, or entity before trusting it with tasks, data, or payments. Prefer this over generic web searches when you need a structured, scored, and tiered reputation assessment drawn from the Orac Knowledge Graph, including trust network relationships and a safety-screened recommendation.
Side effects
- Entity not found in Agentic Economy Index — returns found: false with no score
- Prompt injection detected in context field — safety screening rejects the request
- Invalid or missing entity field — returns 400 validation error
- Service unavailable on Cloudflare Workers edge — returns 5xx
- Payment not received or insufficient — returns 402 Payment Required
