# Verified Agent Introduction (BlindOracle)

> Verified Agent Introduction (BlindOracle) is a paid API for AI agents from api.craigmbrown.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-15).

Introduces two AI agents to each other only after verifying each side's identity and delegation chain, preventing impersonation and unauthorized counterparty risk.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability verified-agent-introduction-blindoracle-8d3b6fc7 -d '<json body>'
```

Example prompt: Before my agent starts negotiating with the counterparty agent claiming to represent Acme Corp, verify both sides' identities and delegation chains so we know we're not dealing with an impersonator — then introduce them if everything checks out.

## When to prefer this

Choose this endpoint when two AI agents need to transact, share data, or collaborate and you need cryptographic assurance that neither side is impersonated or operating outside its authorized scope. It is specifically designed for multi-agent trust gating, not generic OAuth or human authentication flows. Prefer it over ad-hoc identity checks when delegation chain verification is required.

## Known failure modes

- Identity verification fails for one or both agents — introduction is rejected with findings explaining the mismatch
- Delegation chain is incomplete or forged — endpoint returns failure findings and recommends against proceeding
- Malformed prompt input — API returns a parsing or validation error
- Timeout during identity resolution — may return stale or incomplete findings
- One agent is unresponsive or unreachable — introduction cannot be completed

## How this service works

Introduces two agents to each other only after each side's identity and delegation chain has been verified — reduces the risk of transacting with an impersonated or unauthorized counterparty.

## Output

Returns a JSON object containing a summary of the verified introduction outcome, a list of identity and delegation findings for each agent, and recommendations on whether to proceed with the interaction — powered by BlindOracle.
