# Payment Delegation Chain Depth Limit Decision Procedure

> Payment Delegation Chain Depth Limit 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 2026-09-13).

Returns a blunt, agent-ready decision procedure for enforcing and evaluating depth limits in agent-to-agent payment delegation chains, including hop liability, receipt chaining, cycle detection, and audit trail requirements.

## 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 payment-delegation-chain-depth-limit-decision-procedure-30858756
```

Example prompt: Give me the blunt decision procedure for how deep agent-to-agent payment delegation can nest — I need the rules on per-hop liability, receipt chaining, cycle detection, and when to refuse delegation outright.

## When to prefer this

Choose this endpoint when an agent needs a concrete, operational decision procedure for managing delegation chain depth in x402 or agentic payment flows — particularly when building multi-agent systems with nested spend authority, needing cycle detection logic, or requiring auditability across hops. Prefer over generic documentation when you need a blunt, agent-consumable ruleset rather than marketing copy.

## Known failure modes

- Payment not completed returns unpaid/402 response with no procedure content
- Invalid or missing input parameters returns validation error
- LLM generation failure may return ok:false with error detail
- Topic override producing out-of-scope content may degrade procedure relevance
- Network timeout to ascii.dev host

## How this service works

Paid agent-facing brief on agent-facing decision procedure for payment delegation chain depth limits: how deep agent-to-agent spend delegation can nest, per-hop liability and authorization binding, receipt chaining across hops, cycle detection, audit trail, and when to refuse delegation · Build a decision procedure or schema for: agent-facing decision procedure for payment delegation chain depth limits: how deep agent-to-ag. Blunt decision procedure, not marketing.

## Output

A paid JSON response containing a 'brief' field with structured prose decision procedure text covering delegation depth limits, per-hop liability and authorization binding, receipt chaining, cycle detection, audit trail requirements, and explicit refusal conditions — along with metadata like generatedAt timestamp and generationSource.
