x402
Verity Suite Compass Quick is a paid API for AI agents from suite.veritylayer.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).
Given a list of candidate options and constraints, returns a calibrated verdict (recommend, tentative, gather_more_info, or no_viable_option) with confidence score and reasons for the best choice.

How this service works
The trust fabric for AI agents — calibrated, fail-closed services agents pay per call.
Output
Returns a structured verdict object with: a verdict enum (recommend, tentative, gather_more_info, or no_viable_option), the chosen option copied verbatim from the input list (when applicable), a confidence score, a list of concrete reasons grounded in the stated constraints and evidence (including the main tradeoff against the runner-up for recommend/tentative verdicts), and a payment receipt confirming the per-call charge.
Example use cases
Cloud provider selection for a startup
“We're choosing between AWS, GCP, and Azure for our new ML inference workload. Hard requirements are GPU availability and SOC 2 compliance; we prefer lower cost and simpler networking. Use Compass to pick the best one and explain the tradeoff against the runner-up.”
Hiring candidate recommendation
“I have three finalists for our senior engineer role — Alice, Bob, and Carol. The must-haves are 5+ years of Go experience and prior remote work. Nice-to-haves are open source contributions and startup background. Here are their profiles: [Alice: 6yr Go, remote, no OSS; Bob: 5yr Go, remote, active OSS; Carol: 8yr Go, office-only]. Use Compass to recommend who to hire.”
Product feature prioritization decision
“We need to pick one feature to ship next quarter from these three: dark mode, CSV export, and SSO. Our constraints are: must improve enterprise retention (hard gate), prefer low engineering effort, and the team only has 3 weeks. Use Compass to tell me which one to build and why.”
Technical details
Endpoint
POSThttps://suite.veritylayer.dev/compass/quickWhen to prefer
Use this endpoint when an AI agent must make a structured, auditable pick among a discrete set of labeled options and needs a fail-closed, calibrated confidence signal rather than open-ended prose. Prefer it over prompting a general LLM directly when you need a machine-readable verdict enum, a verbatim-matched choice string, and a receipt for the decision. It is especially valuable when the agent must respect hard requirement gates (must-meet constraints that eliminate options) alongside soft preferences, and when you want to avoid hallucinated external facts by supplying explicit evidence.
Side effects
- Missing required fields (options, constraints) returns a validation error
- Options list is empty or has only one item — may return no_viable_option or a trivial recommendation
- Evidence field omitted when options depend on external facts — verdict defaults to what is inferable from constraints alone, potentially less accurate
- Constraints string exceeds 2000 characters — request rejected
- Evidence string exceeds 2000 characters — request rejected
- Payment failure via x402 protocol returns 402 with payment requirements
- Network timeout if upstream processing is slow
- Ambiguous constraints that don't clearly distinguish options may yield a tentative verdict with low confidence
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| options | array | the candidate choices to pick among; one option per item, stated verbatim as you want it returned |
| evidence | — | facts known about the options (specs, prices, availability, data); for any current or external fact, only what is stated here may be used |
| constraints | string | the goal plus hard requirements (must-meet gates), soft preferences (weigh, don't gate), and any priorities or tradeoffs between them |
