PackIndex API

Key endpoints

Python quickstart

Everything a procurement or data team needs to monitor packaging cost exposure:

import requests

API = "https://opnplatform.com/api"
KEY = {"Authorization": "Bearer opn_YOUR_KEY"}

# All live L3 finished packaging unit indices
indices = requests.get(f"{API}/indices", headers=KEY).json()

# Single index with 12-week history — corrugated RSC box
corr = requests.get(f"{API}/indices/CORR", headers=KEY).json()

# Alert on a week-over-week spike
if abs(corr["change_wow_pct"]) >= 3.0:
    notify_procurement(corr)

Node.js quickstart

const API = "https://opnplatform.com/api";
const headers = { Authorization: "Bearer opn_YOUR_KEY" };

// Live raw material prices (L1) — resins, fibre, energy, metals
const commodities = await fetch(`${API}/commodities`, { headers })
  .then(r => r.json());

// Feed a live index into an ERP material master
const pp = await fetch(`${API}/indices/PP`, { headers })
  .then(r => r.json());
updateMaterialMaster("RESIN-PP", pp.value, pp.unit);

ERP integration pattern

Manufacturers and converters wire PackIndex into ERP with a scheduled pull: a weekly job fetches index values, writes them to the material master or purchasing info records, and price conditions reference the stored index. Downstream this powers dynamic BoM cost roll-ups, index-linked purchase contracts, and automated variance reporting — no manual price maintenance. Use the reference JSON schemas for the BoM and price-feed shapes.

Price-spike alerting

Poll pattern — check change_wow_pct on your cadence and alert on a threshold (e.g. ±3%). Managed pattern — PACKIQ market-triggered re-runs automatically re-execute your agents and email results when a tracked index moves ≥3% week-over-week, so traders and buyers hear about the move without watching a dashboard.

Authentication & security

All endpoints run over HTTPS/TLS. Authenticated routes accept an opn_-prefixed API key or Bearer JWT issued from the customer portal. Customer payloads are processed per-request and not retained server-side. Public price tools on the MCP server require no credentials.

AI & agent access

Beyond REST: the MCP server exposes price tools to any MCP-compatible assistant, the A2A agent card serves autonomous agents, and the full OpenAPI 3.0 spec imports into GPT Actions, LangChain, or Postman.
