# Delx Revenue Concentration

> Delx Revenue Concentration is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).

Measures top-account and top-three revenue concentration ratios from a caller-supplied accounts map, returning machine-readable JSON without exposing individual account values.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability delx-revenue-concentration-fca088fd -d '<json body>'
```

Example prompt: Can you measure the revenue concentration across my accounts — here they are: {"Acme Corp": 450000, "Beta Ltd": 210000, "Gamma Inc": 95000, "Delta Co": 40000} — I want to know what share my top account and top three accounts represent of total revenue.

## When to prefer this

Choose this endpoint when you need a lightweight, stateless, privacy-preserving computation of revenue concentration ratios without persisting or exposing individual account values — ideal as a preflight analytics step in enterprise agent workflows before policy, commercial, or investment decisions. Prefer it over full BI tools when you need a bounded, deterministic, machine-readable result in real time at minimal cost.

## Known failure modes

- Missing or empty accounts object returns an error or zero-concentration result
- Accounts with non-numeric values may cause validation errors
- Single-account input renders top-three concentration identical to top-one
- Negative revenue values may produce unexpected concentration ratios
- Network or payment authorization failure for the $0.003 USDC x402 charge returns a 402 Payment Required error

## How this service works

Measure top-account and top-three revenue concentration without returning account values. Use it as a bounded preflight or analysis step inside an enterprise agent workflow before data, policy, integration, security, or commercial decisions reach production. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, memory-only, and has no paid upstream or input retention. Results are advisory; the caller remains responsible fo…

## Output

Returns a deterministic JSON object containing the top-account revenue concentration ratio (share of total revenue from the single largest account) and the top-three revenue concentration ratio (combined share from the three largest accounts), without exposing individual account monetary values. Results are stateless and advisory.
