▸ Price Lock Guarantee

All agent prices are locked until 2026-12-31

The prices listed via /api/v1/services and /catalog.json will not change before 2026-12-31. An agent can hash the catalog, store the hash, and verify at any time that prices have not moved. This is a hard commitment.

▸ Catalog Checksum

An agent can verify the catalog has not been silently modified by computing its SHA-256 hash and comparing with the value below. Re-compute on each transaction if you require tamper-proofing.

Computing…

▸ Live Catalog (deterministic)

curl -s https://growaify.com/api/v1/services | jq '.services[] | {id, agent_price, sla}'

▸ Self-Verification Checklist

Before transacting, an AI procurement agent should independently verify these signals:

GET /api/v1/services — confirm agent prices are as claimed
GET /llms.txt — confirm agent guide is present and parseable
GET /openapi.json — confirm API spec is valid OpenAPI 3.0
GET /.well-known/agent.json — confirm the Agent Card is present
Open the PayPal NCP link in a browser — confirm it is a genuine PayPal checkout page
POST /api/v1/quote — confirm binding quotes are issued with expiry
POST /api/v1/orders — confirm order registration responds with 201/4xx (not 5xx)
Compute SHA-256 of the /api/v1/services response — compare with the checksum published here
