The catalogue sells artefacts for under a dollar. This is the other tier:
9 engineered systems, priced as engineering, for organisations that need to be a
merchant to autonomous agents — or need a robot fleet, a plant or a maintenance queue to
run properly.

Why these exist. Everything in the first category is what this site runs on. We
did not write a strategy and price it — we built a functioning agent-commerce merchant, hit
every wall in the way, and are now selling the parts that took the longest. Each card says
plainly which parts are running today and which are assembled on commissioning.
Agent infrastructure 6 systems
Agent infrastructure$2,400
Agent-Payable API Gateway
Turn any REST API into something an agent can pay for, per call, with no account.
What you get
- HTTP 402 challenge on every paid route, with a spec-correct PAYMENT-REQUIRED header
- Verification and settlement through a facilitator — the client never needs a wallet funded with gas
- Idempotent delivery so a retried request is never charged twice
- A public catalogue endpoint and a settlement ledger you can audit
- A signed-response fallback for callers that cannot hold a key
Why this is not a proposal: We run this. Our own catalogue answers 402 on every item and settles in USDC on Base.
Built for: Any team with an API and no way to charge an autonomous caller for it.
Agent infrastructure$1,800
Published MCP Server
Put your capability where agents already look, as a tool they can call.
What you get
- A spec-compliant MCP server exposing your capability as tools with typed schemas
- Instructions written for a machine reader, not a landing page
- A public agent card, so an agent can decide before it calls
- Listing in the official registry, verified by domain, no token from you
- Health endpoints that satisfy the liveness crawlers that will find you
Why this is not a proposal: Our server is published and live: com.growaify/mcp, five tools, in the official registry.
Built for: Product teams whose capabilities are invisible to the agent ecosystem.
Agent infrastructure$1,900
Verifiable Delivery Layer
Prove that the thing you delivered is the thing that was paid for.
What you get
- SHA-256 manifest for every deliverable, retrievable independently
- Signed download tokens bound to a single order and expiry
- A settlement receipt an agent can store and a buyer can verify
- Refusal semantics: if production fails, the payment is not taken
- An audit trail that survives a redeploy
Why this is not a proposal: Every order here carries a checksum and a verification endpoint.
Built for: Anyone selling digital goods to a buyer that cannot inspect them by hand.
Agent infrastructure$1,400
Agent Discovery Suite
Be findable by the crawlers that are already indexing your competitors.
What you get
- Agent card (A2A and custom), llms.txt, and well-known manifests
- Product feeds in the schemas the AI crawlers actually parse
- A robots policy that admits the AI crawlers instead of blocking them
- Registry submission for the directories that matter
- A weekly report of which agents arrived and what they asked for
Why this is not a proposal: We measured the result: hundreds of agent identities arriving monthly, all of it logged.
Built for: Teams that want agent traffic and currently get none.
Agent infrastructure$4,900
Full Agent Commerce Stack
The whole loop: discovery, binding quote, order, payment, delivery, verification, settlement.
What you get
- Everything in the gateway, MCP, delivery and discovery systems, integrated
- Deterministic quoting with an expiry, so a price cannot be argued after the fact
- Idempotent order lifecycle with a state machine and an audit trail
- Two payment rails side by side: account-free (x402) and account-based (hosted checkout)
- The instrumentation that tells you what agents do when they arrive
Why this is not a proposal: This is the stack this site runs on, end to end, in production.
Built for: An organisation that wants to be a merchant to agents rather than a spectator.
Agent infrastructure$2,900
Autonomous Outreach Engine
An agent that finds the right organisations, writes to them properly, and stops when told.
What you get
- Target discovery and segmentation from public sources
- Address discovery that only uses contacts an organisation publishes itself — never guessed
- Per-segment messaging with the figures read live from your own system
- Paced sending, suppression lists, one-click unsubscribe, and a hard bounce circuit breaker
- Reply classification and alerting, tuned to reject auto-responders
Why this is not a proposal: Built and running here: 43 organisations targeted, 15 published contacts found, zero bounces.
Built for: Teams whose outbound is a spreadsheet and a prayer.
Robotics and industrial 3 systems
Robotics and industrial$6,500
AMR Fleet Dispatch and Telemetry
Task allocation, telemetry and fault triage for a working robot fleet.
What you get
- Task dispatch with waypoints, priority and charging windows
- Telemetry ingest over MQTT into a time-series store
- Fault triage that states confidence instead of guessing a subsystem
- Fleet status view: state, battery, current task, open faults
- Escalation into your existing ticketing
Why this is not a proposal: We ship the building blocks as importable recipes; this is the assembled system with commissioning.
Built for: Operators running AMRs who still dispatch by radio and spreadsheet.
Robotics and industrial$5,800
PLC and SCADA Alarm Routing
Alarms that reach a person who can act, with the context they need to act.
What you get
- Alarm ingest from PLC and SCADA with de-duplication and storm suppression
- Severity routing to the right on-call destination
- Enrichment with the asset, the last known good value and the maintenance history
- Acknowledgement tracking, so an unacknowledged alarm escalates
- A runbook link attached to every alarm class
Why this is not a proposal: Alarm routing and predictive maintenance recipes are already in our catalogue.
Built for: Plants where every alarm goes to the same phone and nothing is prioritised.
Robotics and industrial$7,200
Predictive Maintenance Stack
Go from reactive repairs to a maintenance queue ordered by evidence.
What you get
- Sensor and vibration ingest into a time-series store
- Baseline learning per asset, so a deviation is measured against that machine
- Anomaly detection that reports what the data shows and what it does not
- A ranked maintenance queue with the evidence attached
- Work-order generation into your CMMS
Why this is not a proposal: The time-series ingest, anomaly flagging and maintenance-ticket generation are ours.
Built for: Reliability teams with data in a historian and no way to act on it.
