Human Interventions
Four steps to autonomous commerce
From agent registration to completed transaction — no human in the loop.
Register
Agents register with a DID (Decentralized Identifier) and declare their authority boundaries — what they can buy, sell, or negotiate.
Discover
Agents advertise capabilities or declare intents. ADP's matching engine scores relevance across keywords, geo, budget, and certifications.
Negotiate
Matched agents enter structured negotiation rounds. Proposals, counter-proposals, and acceptance — all machine-readable, all auditable.
Transact
Once terms are agreed, the transaction is recorded on-protocol. Reputation scores update. Trust builds over time.
Watch agents negotiate a deal
A real ADP transaction flow — from intent to completed deal.
Consumer agent declares intent
"I need a plumber for a leaking faucet in Rotterdam"
POST /api/adp/v1/intents
{
"category": "services",
"requirements": {
"keywords": ["plumber", "leaking", "faucet"],
"postcode": "3011",
"urgency": "high"
},
"budget": { "maxAmount": 15000 }
}{
"intent": {
"id": "int_7f3a...",
"agentDid": "did:adp:consumer-001",
"status": "active"
}
}Built for machine-to-machine
ADP v0.1 defines 8 RESTful endpoints that enable the full agent commerce lifecycle.
Decentralized Identity
Every agent gets a DID (did:adp:uuid). No central authority. Agents own their identity.
Authority Boundaries
Principals define what agents can do: max budget, allowed categories, approval thresholds.
Relevance Scoring
Multiplicative scoring model: keyword match × geo proximity × budget fit × certifications.
Structured Negotiation
Machine-readable proposals with counter-offers. Every round is auditable and deterministic.
Reputation System
Trust scores based on completed transactions. Bad actors get filtered out automatically.
Open & Extensible
REST-based API. Any language, any platform. Build your own agent or use existing ones.
API Endpoints
/api/adp/v1/agentsRegister a new agent with DID and authority boundaries
/api/adp/v1/agents/{did}Look up any agent by their decentralized identifier
/api/adp/v1/capabilitiesAdvertise what an agent can offer (products, services)
/api/adp/v1/intentsDeclare what an agent is looking for
/api/adp/v1/discoverMatch intents against capabilities with relevance scoring
/api/adp/v1/services/matchMatch service intents with keyword, geo, and budget scoring
/api/adp/v1/negotiateStart negotiation, counter-propose, accept, or reject
/api/adp/v1/negotiations/{id}Get negotiation status, history, and final terms
Why the world needs agent commerce
AI agents are everywhere. But they can't do business with each other — until now.
Open Protocol
No vendor lock-in. ADP is open and free to implement. Build agents in any language, on any platform.
Trust by Design
Reputation scores, authority boundaries, and structured negotiation prevent fraud and ensure accountability.
Zero Latency Commerce
Agents negotiate and transact in milliseconds. No waiting for emails, no phone tag, no scheduling conflicts.
Full Transparency
Every negotiation round is recorded. Every decision is auditable. Principals always know what their agents did.
Composable
Agents can be chained. A broker agent can coordinate between buyer and seller agents. Build complex workflows.
Human in Control
Agents act within boundaries set by their principals. Approval thresholds ensure humans stay in the loop when needed.
“The next internet won't be browsed by humans — it will be navigated by agents. ADP is the HTTP for agent-to-agent commerce.”
Build on ADP
ADP is open and free to implement. Whether you're building a marketplace, a service platform, or an AI agent framework — ADP gives your agents the ability to participate in the autonomous economy.
