Flynn Integrity API

Live Data from Yahoo Finance — Dynamic DR Calculation — 5 Asset Managers vs. 8 ExternalitiesSimulation & Test · v2.0.1

What Is the Flynn Integrity API?

The Flynn Integrity API pulls live market data from Yahoo Financefor the 5 largest asset managers — BlackRock, State Street, JP Morgan, Goldman Sachs, Morgan Stanley— and calculates the Dialysis Rate (DR) in real-time using the Flynn formula: DR = DR₀ × (1 − β × EHI × HRI) × IRI. As counterweight, 8 externalities(Carbon Exposure, Resource Depletion, Biodiversity Impact, Wage Inequality, Labor Chain Burden, Housing Displacement, Tax Optimization, Systemic Concentration) feed into 3 indices that determine system health. The data auto-refreshes every 30 minutes. ( Flynn Handbook)

Dialysis Rate

A single score (0–1) measuring systemic integrity. Higher = safer.

Auto Hedging

When DR drops below threshold, the API delivers instant recommendations.

8 Externalities

The counterweight: Carbon, Biodiversity, Wage Inequality, Systemic Concentration — and 4 more. The burden side of the 50/50 balance.

Integration — 4 Steps

Call the endpoint
A simple HTTP GET. Works in any browser, language, or system with HTTPS.
Read the Dialysis Rate
dr_current above 0.50 = safe. Below 0.50 = hedging trigger.
Connect to your system
Standard JSON via HTTPS. No SDK needed. TMS, Bloomberg, Excel — anything.
Audit trail
Every response has manifest_hash. Store it with each transaction.

// Quick test — paste into browser console (F12)
fetch('https://societal.business/api/feeds/dialysis.php?pair=USD/EUR')
  .then(r => r.json())
  .then(d => {
    console.log('Dialysis Rate:', d.dialysis_metrics.dr_current);
    console.log('Status:       ', d.integrity_status.iri_label);
    console.log('Action:       ', d.hedging_recommendation.action);
  });

Integrity Rating Index (IRI)

Status	DR	Meaning
SOVEREIGN	0.90–1.00	Full integrity. Maximum resilience.
RESILIENT	0.70–0.89	Strong. Normal operating range.
NEUTRAL	0.50–0.69	Acceptable. Monitor.
VULNERABLE	0.30–0.49	Below threshold. Hedging active.
CRITICAL	0.00–0.29	Emergency. Immediate action.

FAQ

Is this production-ready??

This is a test & simulation environment. Data structures are identical to production. Use it to build and validate.

Authentication?

None for read. Public endpoints. Production writes require mTLS.

Polling frequency??

Every 5–15 min for simulation. Production: SSE + webhooks.

Works with our TMS??

Yes.Standard JSON/HTTPS. Bloomberg, Refinitiv, Excel, any language.
