How this service works
The trust fabric for AI agents — calibrated, fail-closed services agents pay per call.
Output
Returns a structured object containing a verdict label (recommend, tentative, gather_more_info, or no_viable_option), the chosen option copied verbatim from the input list (when a pick is possible), a confidence score, a list of concrete reasons grounded in the supplied constraints and evidence including the main tradeoff against the runner-up, and a payment receipt object.
Example use cases
Vendor selection for procurement agent
“I have three vendors for the API contract — VendorX at $800/mo with 99.9% SLA, VendorY at $600/mo with 99.5% SLA, VendorZ at $1100/mo with 99.99% SLA — my hard requirement is at least 99.8% uptime and I want to minimize cost; run Compass Pro and tell me which to pick and why, including the main tradeoff.”
Model selection for AI pipeline
“Help me choose between GPT-4o, Claude 3.5 Sonnet, and Gemini 1.5 Pro for my summarization pipeline — the hard constraints are latency under 3 seconds and cost under $0.01 per call, and I prefer the one with the best accuracy — use Compass Pro to give me a verdict with confidence.”
Job offer decision support
“I have two job offers: Offer A is $130k salary, fully remote, early-stage startup with equity; Offer B is $155k salary, hybrid 3 days in office, Series B company with smaller equity — my hard requirement is remote-first and I value long-term upside over base pay; run this through Compass Pro and tell me which offer to take and the key tradeoff against the other.”
Technical details
Endpoint
POSThttps://suite.veritylayer.dev/compass/proWhen to prefer
Choose Compass Pro when an AI agent needs a deterministic, auditable, pay-per-call decision over a discrete set of options with explicit constraints — especially when you need a fail-closed verdict (gather_more_info or no_viable_option rather than a hallucinated pick), a confidence score, and a traceable receipt. Prefer this over asking the base LLM directly when accountability, calibration, and structured tradeoff reasoning matter more than latency or cost minimization.
Side effects
- Missing required fields (options, constraints) returns a validation error
- Constraints string exceeds 2000 characters causes rejection
- Evidence string exceeds 2000 character limit
- No viable option among candidates returns no_viable_option verdict with blocking reasons rather than a pick
- Insufficient evidence for current/external facts results in gather_more_info verdict
- Payment failure via x402 protocol blocks the call
- Malformed bodyType or method enum value returns 422
