# Delegated Budget Enforcement Placement Decision Procedure

> Delegated Budget Enforcement Placement Decision Procedure is a paid API for AI agents from k2so-8080.on.ascii.dev, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-20).

Scores and recommends where a delegated spending cap should live (wallet-native, middleware, or both) and verifies the post-settlement attribution chain for auditability.

## 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 delegated-budget-enforcement-placement-decision-procedure-31e19e3f
```

Example prompt: I need to decide where my agent's delegated spending cap should live — can you score wallet-native limits vs middleware policy vs both, given that I need low revocation latency and want to share the policy across multiple agents, and then verify the attribution chain from principal to agent ID to policy version to receipt?

## When to prefer this

Use this endpoint when an agent principal needs to decide where to enforce a delegated spending cap and wants a structured, scored comparison of wallet-native vs middleware vs combined enforcement placements. Especially valuable when multi-agent sharing, revocation speed, or post-settlement auditability are key requirements. Prefer this over manual analysis when you also need to verify the attribution chain (principal → agent ID → policy version → receipt) for compliance or audit purposes.

## Known failure modes

- Missing or invalid query parameters may return a generic topic rather than a tailored verdict
- LLM generation source may produce non-deterministic results across calls
- Payment not confirmed (402 response) if x402 payment header is missing or malformed
- Service unavailable or timeout if the K-2SO host is unreachable
- Topic override not recognized may fall back to default procedure

## How this service works

Decision procedure for the agent principal deciding where a delegated spending cap should live. Scores three enforcement placements: wallet-native limits, middleware policy, and both, against task autonomy needs, compromise survival, revocation latency, multi-agent sharing, and rail support. Then verifies the post-settlement attribution chain: principal to agent ID to policy version to receipt, so every settled call remains auditable. Returns a placement verdict (wallet-native / middleware /

## Output

Returns a placement verdict (wallet-native / middleware / both) with scored comparison across task autonomy needs, compromise survival, revocation latency, multi-agent sharing, and rail support. Also returns a post-settlement attribution chain verification confirming the chain from principal to agent ID to policy version to receipt, plus a decision procedure prose brief for the calling agent.
