# Delx Saturation Ratio

> Delx Saturation Ratio 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).

Computes capacity saturation ratio from in-flight work units and maximum capacity, returning a deterministic machine-readable JSON result

## Facts

- Endpoint: POST https://api.delx.ai/api/v1/x402/saturation-ratio
- Price: $0.003/call
- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-saturation-ratio-b91c81b2 -d '<json body>'
```

Example prompt: What's the saturation ratio for my service right now — I have a max capacity of 500 and 340 units currently in flight?

## When to prefer this

Choose this endpoint when you need a fast, stateless, zero-dependency computation of capacity saturation with no upstream data calls. Ideal for SRE/ops agents composing health scores from raw telemetry, or when you want deterministic math at minimal cost ($0.003 USDC) without integrating a full observability platform. Prefer over manual calculation when building automated pipelines that need machine-readable JSON output.

## Known failure modes

- Missing required field (capacity or in_flight) returns a validation error
- Capacity value of zero causes a division-by-zero error
- Non-numeric input values return a type error
- Negative values may produce unexpected or invalid ratios
- Payment failure via x402 prevents execution and returns a 402 response

## How this service works

Compute capacity saturation from in-flight work and capacity — call when measuring in-flight work against capacity. Use for SRE/ops math agents buy from broad utility catalogs: SLA, error budget, success rate, and health scores with zero upstream cost. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web search, or media generat…

## Output

A deterministic JSON object containing the computed saturation ratio (in-flight divided by capacity), indicating what fraction of total capacity is currently consumed. Useful as a standalone metric or as an input to composite health scores.
