How this service works
Ask up to 20 typed yes/no, multiple-choice or ordinal-scale questions about one shared piece of context in a single call - each answered with a real probability (Jev decision primitives), not generated text. Try GET /decide/sample.
Output
A structured response keyed by each question name you provided, where each entry contains a typed probabilistic answer: a real-valued probability for yes/no questions (noul), a probability distribution over choices for multiple-choice questions, and a calibrated numeric score for ordinal-scale questions — all computed over the shared context, not generated as text.
Example use cases
Resume screening against job criteria
“I have a resume and five hiring criteria — does the candidate have 5+ years of experience, are they likely a culture fit, do they have leadership experience, which role tier fits best (junior/mid/senior), and rate their technical depth 1–5. Run all five as decision questions on this resume text and give me the probabilities.”
Content moderation policy check
“Take this user-submitted post and ask: is it likely spam (yes/no), does it violate our community guidelines (yes/no), which violation category fits best (hate speech, misinformation, adult content, none), and rate its toxicity on a 1–10 scale — all as calibrated probabilities in one call.”
Investment memo quality assessment
“Here's an investment memo — ask whether the market opportunity is clearly defined, whether the team section is convincing, which funding stage is implied (pre-seed, seed, Series A, Series B+), and score the overall investment thesis strength from 1 to 5. Return real probabilities, not just labels.”
Technical details
Endpoint
GEThttps://x402.agentindex.world/decide?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need calibrated probability outputs rather than free-form generated text, and especially when you have multiple structured questions about the same context that should be answered consistently in a single pass. It is ideal for evaluation pipelines, rubric-based scoring, content moderation, and decision workflows where deterministic, numeric confidence values matter more than natural language explanations. Prefer it over LLM-generated answers when you need machine-readable probabilities for downstream logic.
Side effects
- Context exceeds 8000 token cap — request rejected or truncated
- More than 20 questions submitted — excess questions ignored or error returned
- Malformed question type (not 'noul', 'choice', or 'score') — validation error
- Missing required question fields (type, instructions, criteria) — error per question
- Payment failure via x402 protocol — call not executed
- Ambiguous or contradictory criteria leading to poorly calibrated probabilities
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| state | — | Shared context the questions are asked about - a string, or a JSON object/array. Capped at 8000 tokens. |
| questions | object | Up to 20 typed questions, keyed by a name you choose. Each needs type ('noul', 'choice' or 'score'), instructions, and criteria (shape depends on type - see /decide/sample). |
