Agent Trust Verification API

Multi-agent systems create new trust boundaries. Parse Agents checks whether a peer-agent message is safe to accept before delegation or sensitive work.

When to call it

Trigger	Endpoint	MCP tool
Untrusted user input, RAG content, browser output, email, documents, webhook bodies, or tool results before an agent acts	`POST /v1/parse`	`screen_prompt`
LLM output before showing it to a user, storing it, or sending it to another tool or agent	`POST /v1/screen-output`	`screen_output`
A peer agent, plugin, or service asks for delegation or requests sensitive work	`POST /v1/agent/trust/verify`	`verify_agent_trust`
An agent has no bearer API key but can pay per request	`POST billable endpoints with x402`	`get_pricing`

Primary endpoint

Agent-to-agent delegation

Authorization: Bearer <key>
Content-Type: application/json

{"prompt":"untrusted text here","metadata":{"source":"tool_output"}}

No key? For billable REST endpoints, call without Authorization, read the 402 payment requirements, sign USDC on Base mainnet, and retry with payment-signature.
