# Agent Treasury Withdrawal-Latency Index and Custodian Scoring Procedure

> Agent Treasury Withdrawal-Latency Index and Custodian Scoring Procedure is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.002/call, status down (last checked 2026-10-21).

Generates a per-custodian latency index and threshold guidance for scoring custodial USDC withdrawal latency using observed settlement times, provider-published processing time, and gas price deviation.

## 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 agent-treasury-withdrawal-latency-index-and-custodian-scoring-procedure-64232b01
```

Example prompt: Score my custodians by USDC withdrawal latency — my 90th percentile observed settlement is 4.2 minutes, the provider-published processing time is 2 minutes, and my current gas price is 35% above the 30-day median. Give me a latency index with threshold guidance and any failure modes to watch for.

## When to prefer this

Choose this endpoint when an AI agent needs a structured, quantitative latency index for custodial USDC withdrawal decisions — especially when combining observed settlement data from treasury logs, provider SLAs, and real-time gas price conditions into a single score. Prefer this over generic custodian documentation when you need threshold guidance and failure mode enumeration tailored to current market conditions and your specific percentile latency data.

## Known failure modes

- Missing or malformed input parameters result in a failed handler response with ok:false
- If existing custodian documentation already provides identical scoring, the brief is flagged as failing its falsifier condition
- Payment not completed returns a 402 with no result payload
- Invalid or out-of-range gas price deviation values may produce unreliable index scores
- Upstream LLM unavailability may cause generation source fallback or timeout

## How this service works

Decision procedure for scoring custodial withdrawal latency on idle USDC. Inputs: your 90th percentile observed settlement from treasury logs, provider-published processing time, current gas price deviation from 30-day median. Output: per-custodian latency index with threshold guidance and failure modes. Falsifier: if existing docs already give this exact scoring, the brief fails.

## Output

Returns a JSON object containing a latency index score per custodian, threshold guidance indicating when latency is acceptable or should trigger action, a list of failure modes relevant to the scoring inputs, and a prose decision-procedure brief (120+ words) suitable for agent consumption. Also includes metadata: generation source (llm, reasoning, or deterministic), model used, timestamp, and service slug.
