PayPerWork Decide v1 SystemOne is a paid API for AI agents from payperwork.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-11-02).
Evaluates a decision model defined by a typed state and questions (yes/no, choice, score), returning answers as probabilities in a single pass with no generated text.

How this service works
Decision models for agents: a state plus typed questions (noul yes/no, choice, score) answered as probabilities in one pass, no generated text.
Output
Returns probability distributions for each typed question: yes/no questions yield a probability for true/false, choice questions yield a probability per option, and score questions yield a probability-weighted score — all computed in a single inference pass with no generated text.
Example use cases
Content moderation policy check
“Given this post's metadata — topic, length, author reputation score, and flag count — evaluate whether it violates policy (yes/no), which category of violation it most likely falls into (choice: spam, harassment, misinformation, off-topic), and how severe the violation is (score 0–10). Return probabilities for each.”
Lead qualification scoring
“I have a sales lead with these attributes: company size 50 employees, industry SaaS, job title VP of Engineering, and they visited the pricing page twice. Evaluate the decision model: is this a qualified lead (yes/no), which product tier fits best (choice: starter, growth, enterprise), and score their buying intent from 0 to 10.”
Loan eligibility decision
“Given this applicant's state — credit score 720, income $85k, existing debt $12k, employment type salaried — run the decision model to decide if they're eligible for a loan (yes/no), which loan product fits best (choice: personal, secured, line-of-credit), and rate their creditworthiness from 0 to 10 as probabilities.”
Technical details
Endpoint
POSThttps://payperwork.app/decide/v1/systemone?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured probabilistic answers to typed decision questions (yes/no, choice, score) against a defined state, without any generated natural-language text. It is ideal for agents that need fast, cheap, repeatable classification or scoring in a single pass — preferred over a chat completions endpoint when you want no hallucinated prose, deterministic output structure, and cost-efficient ($0.001/call) bulk decisioning.
Side effects
- Malformed state object causes a 400 validation error
- Unsupported question types return an error indicating invalid schema
- Questions with ambiguous or contradictory state may yield flat/uniform probability distributions
- Rate limiting or payment failure returns a 402 or 429 error
- Network timeout if state payload is very large
