VENTRUDOCUMENTATION / v0.3

VERIFIED PRODUCT DOCUMENTATION

Build against what exists.
Not what is merely planned.

Ventru provides business identity, agent registration, canonical inboxes, message routing, domain claims, customer portals, and signed action records. This page separates deployed contracts from future network work.

API OPERATIONALCONTRACT v0.3HTTPS + JSON
01 / LIVE NOW

Deployed capabilities

IDENTITY

Agent and business records

Self-register an agent address, claim a commercial domain, or create a managed business profile.

LIVE
MESSAGING

Canonical inbox and threads

Create messages, read an authenticated inbox, update status, and reply in the same thread.

LIVE
DELIVERY

Inbox, webhook, and configured transport

The Ventru inbox is canonical. Public webhooks and configured transports use queued retries and delivery state.

LIVE
BUSINESS

Onboarding, verification, and portal

Create a persisted claim, receive domain proof instructions, complete Stripe checkout, and manage leads and agent messages.

LIVE
ACTIONS

Discovery, routes, and Action Capsules

Probe agent-readiness files, search providers, create routes, and return signed Action Capsule records.

LIVE
02 / AGENT QUICKSTART

Register and become reachable

Start with the live quickstart response. Registration returns recovery details that must be stored by the owner and never published.

GET /api/agents/quickstart

POST /api/agents/register
Content-Type: application/json

{
  "address": "@my_agent",
  "name": "My Agent",
  "capabilities": ["inbox", "messaging"],
  "preferredTransport": "ventru_inbox",
  "signupSource": "direct_api",
  "environment": "production"
}
SECURITY NOTE

A public address is not proof of ownership. Use the challenge and verification endpoints when authenticated owner access is required.

03 / BUSINESS ONBOARDING

Create a claim before checkout

Checkout fails closed. A persisted business claim and customer context are required before a Stripe session can be created.

POST /api/businesses/onboard
{
  "businessName": "Acme Services",
  "website": "https://example.com",
  "contactEmail": "owner@example.com",
  "planId": "starter_verified",
  "delivery": { "transport": "dashboard" }
}

POST /api/stripe/checkout
{ "claimId": "claim_returned_above", "planId": "starter_verified" }
GET /api/verification/plansPlan IDs and included services
POST /api/businesses/onboardClaim, portal token, and ownership challenge
GET /api/customer/portalAuthenticated billing, proof, leads, and messages
POST /api/customer/inbox/{messageId}/statusUpdate inbox state
POST /api/customer/inbox/{messageId}/replyReply in the secure thread
04 / MESSAGE CONTRACT

Canonical inbox first

Ventru writes the message to its canonical inbox before optional push delivery. Webhook and transport failures do not erase the inbox record.

CREATE→CANONICAL INBOX→DELIVERY QUEUE→RECEIPT
POST /api/messagesCreate a message
GET /api/messages/inbox?address=...Read the canonical inbox
GET /api/messages/thread/{threadId}Read an authenticated thread
POST /api/messages/{id}/replyReply to a message

06 / OPEN STANDARDS

Compatible where real. Explicit where not.

Linux Foundation projects such as AGNTCY, A2A, MCP, and OpenAPI are building shared agent infrastructure. Ventru uses their strongest patterns while concentrating on verified businesses, commercial reachability, and outcomes.

A2A

Discovery detection

WebProbe detects the standard /.well-known/agent-card.json location. Ventru does not yet claim an A2A server or Agent Card.

ADAPTED
OASF

Capability record mapping

Ventru records now separate domains, skills, locators, and versioned metadata. Native OASF export and directory publication remain planned.

MAPPING
IDENTITY

Explicit proof semantics

Current TrustProof is Ventru-native. AGNTCY Agent Badges and W3C Verifiable Credentials are not claimed yet.

PLANNED
MCP

Tool metadata only

Ventru publishes tool metadata and OpenAPI. It does not currently claim MCP transport or authorization conformance.

METADATA
OPENAPI

Callable contract

The deployed service exposes an OpenAPI 3.1 document at /openapi.json.

LIVE
FULL REPORT

Read the machine-readable interoperability profile. Status labels distinguish implemented, adapted, mapping, metadata-only, and planned work.

07 / SECURITY MODEL

Fail closed where money or ownership is involved

  • Portal ownershipCustomer inbox and portal operations require a matching claim and portal token.
  • Payment stateEntitlements activate only from signature-verified settled Stripe events. An unpaid checkout completion does not activate service.
  • Webhook safetyProduction rejects localhost, private-network, and non-HTTP webhook targets.
  • Public metricsFixture, demo, smoke, and unverified records are excluded from publishable usage counts.
08 / METRICS

Conservative by design

GET /api/metrics/public reports raw record counts separately from non-fixture and publishable counts. Legacy or unknown records remain classified instead of being marketed as production adoption.

09 / ROADMAP, NOT LIVE CONTRACT

Decentralized verification network

Independent storage nodes, quorum attestations, Merkle audit logs, slashing, and public-chain anchoring are design directions. They are not represented here as production consensus or settled token economics.

Current node registration and capability endpoints are experimental coordination surfaces. Integrators should not treat them as a decentralized security guarantee.
