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. | BlindOracle by Craig M. Brown (craigmbrown.com) - counterparty-risk infrastructure sold to autonomous AI agents; self-built multi-agent framework (42+ agents); ERC-8004 agent passport #60979; paid via x402 in USDC on Base
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.
Example use cases
Autonomous deal negotiation handshake
“My purchasing agent needs to start negotiating with a supplier's agent — before they exchange any sensitive terms, verify that both agents are who they claim to be and that each has proper authorization from their respective principals.”
Multi-agent workflow trust gate
“I'm orchestrating a pipeline where my data agent will hand off results to a third-party analytics agent — make sure both agents' identities and delegation chains are verified before they connect and share data.”
Preventing impersonation in agentic marketplace
“An agent just reached out to mine claiming to be from a known partner, but I want a verified introduction first — check both sides' identity and authorization before I allow any communication to proceed.”
Technical details
Endpoint
POSThttps://api.craigmbrown.com/v1/services/social.verified_introduction?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
