Getting Started

The Skylife Research Graph API gives you per-stock network-centrality statistics
over the Indian NIFTY-50.

The mental model

Every trading session we take the recent price candles of the NIFTY-50 and build a
correlation graph: each stock is a node, and an edge joins two stocks whose
returns move together. That graph is rebuilt from scratch each session, so it always
reflects current market structure. On top of it we compute five classic
centrality metrics — each one a different way of measuring where a stock sits in
the web of co-movement: is it a hub, a bridge, or out on the periphery?

The five metrics (all computed on the correlation graph):

Metric	Meaning
`degree_strength`	Normalized weighted degree — how strongly connected the stock is.
`eigenvector_centrality`	Influence via well-connected neighbours.
`betweenness_centrality`	How often the stock bridges shortest paths between others.
`closeness_centrality`	Inverse mean distance to every other stock.
`pagerank`	Random-walk importance (weight-biased PageRank).

60-second quickstart

1. See the shape — no token needed

The public demo endpoint returns fixed sample data in the exact shape of the live
response. Hit it with curl (or click Try It on the reference page):

curl https://graph-api.skyliferesearch.com/v1/demo/chart

You get the standard envelope:

{
  "success": true,
  "errors": null,
  "data": {
    "type": "snapshot",
    "asof_date": "2026-07-14T15:30:00",
    "metrics": ["degree_strength", "eigenvector_centrality", "betweenness_centrality", "closeness_centrality", "pagerank"],
    "graph": { "nodes": 5, "edges": 4, "method": "mst" },
    "stocks": [
      { "symbol": "ICICIBANK", "degree_strength": 1.0, "pagerank": 0.244902 }
    ]
  },
  "meta": { "generated_at": "2026-07-15T09:32:11Z" }
}

2. Get a token, then call the live endpoint

Sign in with Google at skyliferesearch.com.
Open Dashboard → API access → Generate token and copy the 24-hour Bearer token.
Call the live endpoint:

curl https://graph-api.skyliferesearch.com/v1/graph-stats/chart \
  -H "Authorization: Bearer $SLR_TOKEN"

That returns a live snapshot for the full NIFTY-50. Add query params to change the
window, graph method, or metrics — or set periods>1 for a rolling time series. See the
API reference for every parameter.

Next steps

Authentication — obtaining and using your Bearer token.
Rate Limits — 1 request/minute, 30/day, and the headers.
Errors — the envelope and every error code.
