How this service works
Machine-payable service intelligence for discovering, verifying, and monitoring identity, risk, authorization, execution-preflight, and evidence APIs before autonomous agents spend.
Output
Returns a JSON object with network context (e.g. 'eip155:8453'), product identifier ('nomos-goal-mandate-provenance'), and an assessment object containing a risk_level string (e.g. 'low'), a numeric risk_score, and an array of compliance flags (empty if none). This allows an agent or orchestrator to decide whether to proceed with the action.
Example use cases
Preflight check before DeFi action
“Before the agent swaps tokens on my behalf, verify with Nomos that the action 'swap USDC to ETH' is consistent with its mandate 'manage DeFi portfolio' and goal 'maximize yield', and tell me the risk score.”
Autonomous agent authorization audit
“I'm deploying agent 'agent-scheduler-7' with mandate 'schedule and send marketing emails'. Before it sends a campaign, can you verify that its requested action 'send bulk email to subscriber list' matches its mandate and flag any risks?”
Multi-agent pipeline safety gate
“We're running a pipeline where agent 'orchestrator-01' has mandate 'coordinate data analysis tasks'. Before it delegates to a sub-agent, verify that the requested action 'write to production database' is within its mandate and return whether it's low, medium, or high risk.”
Technical details
Endpoint
POSThttps://base-agent-preflight.bytoken2023.workers.dev/x402/v1/agent/mandate/verifyWhen to prefer
Use this endpoint when you need a structured, paid preflight compliance check specifically for autonomous agents acting on declared mandates — particularly in agentic pipelines on Base/EVM networks where mandate provenance and risk scoring are needed before irreversible actions. Prefer this over generic authorization APIs when you need agent-specific risk scoring tied to goal-mandate alignment rather than simple role-based access control.
Side effects
- Missing required fields (agent, mandate, requested_goal, requested_action) return validation errors
- Unknown or unrecognized agent identifiers may result in inconclusive assessments
- Payment failure via x402 protocol results in 402 response and no assessment
- High-risk actions return populated flags array requiring human review
- Service unavailability on Cloudflare Workers returns 5xx errors
