# Agent On-Behalf-Of (OBO) Mandate Validator

`POST /v1/tools/validate_agent_obo_mandate`

## Request

- Base URL: `https://ainumbers.co`
- URL: `https://ainumbers.co/v1/tools/validate_agent_obo_mandate`
- Auth: none declared

Validate an agent on-behalf-of (OBO) mandate: subject (the user being represented), bounded scope array, intent string, and a non-expired validity window (caller-supplied now_unix, no clock reads). Mismatch or expiry returns REFUSE. Aligns with the AP2 mandate-chain pattern (art-01). Consumes scope-revocation audit (art-150), feeds task lifecycle validator (art-152). Zero network, zero PII.

**Tool URL:** https://ainumbers.co/chaingraph/art-151-agent-obo-mandate-validator.html
**AP2/Policy Mandate export:** yes
