You send a state (text, JSON or up to 4 images) and one or more closed questions. The API returns typed answers (a yes/no probability, a choice or a score) with probabilities and a calibrated confidence. It is used for ticket triage, content moderation, agent evaluation, contract review and listing review. This server is a transparent proxy in front of Modaic's own API that sells access on plans (credit or subscription) rather than per call: it handles identity, payment, and proxying. Agents can purchase autonomously or with their human's approval. The complete verified paid surface is listed at /openapi.json, the source of truth for available operations. Each operation here carries its pricing in x-payment-info. Use the operations and details here when they meet your needs. Filtered specs contain only matching operations; if you cannot find what you need here, use search or the service catalog. The live catalog at /manifest.json is authoritative for prices and any free included units (prices[].includedUnits) - some meters include free usage per account before any charge, reserved for agents claimed by a human with a verified email.","url":"https://agents.modaic.dev/zeroclick/agent/quote?utm_source=zero.xyz","method":"POST","headers":{},"bodySchema":{"type":"object","properties":{"goal":{"type":"string","maxLength":2000,"minLength":1,"description":"Describe the task and known inputs.
