Systemone
by x402.jev in Onchain & crypto
Answer typed questions about a state. Demo only, after explicit user confirmation of /SKILL.md terms. No production or consequential real-world decisions. Returns one answer per question: a yes probability (noul), an option and distribution (choice), or a rubric rating (score). Confidence is not proof of correctness. The response reports model and token usage; pay only against the live 402 quote for the request.

}Parameters
| Parameter | Type | Required | Description |

questions | object | Yes | A map of question id to question. Answers come back under the same ids; the ids themselves are not sent to the model. |
state | string or object or array | Yes | Shared text or structured JSON context for all questions. Use named fields for multiple records or facts. Jev evaluates text, not raw images, audio, or video. |
Example response

}Call it from code
The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.0002.
The code pays $0.0002 in USDC on Base instead: it uses a payment scheme other than exact, which needs a different client setup.
