# Agent Payment Lifecycle Next Phases: Streaming LLM Settlement, Delivery Receipt Verification & Escrow Wiring

> Agent Payment Lifecycle Next Phases: Streaming LLM Settlement, Delivery Receipt Verification & Escrow Wiring 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 2026-10-19).

Returns a paid decision-procedure brief covering streaming LLM usage settlement timing, per-merchant delivery receipt verification, and escrow evaluation settlement wiring for AI agents using x402/MPP payment rails.

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 agent-payment-lifecycle-next-phases-streaming-llm-settlement-delivery-265bf86e
```

Example prompt: Can you pull the decision procedure for when to keep an x402 streaming session open versus settling mid-stream, including per-token cost drift gates and how to verify a merchant delivery receipt before wiring escrow?

## When to prefer this

Use this endpoint when an AI agent needs authoritative, structured decision-procedure guidance on x402/MPP streaming payment lifecycle management, specifically covering when to settle or sustain streaming LLM sessions, how to verify merchant delivery receipts, and how to wire escrow settlement. Prefer it over generic documentation when the agent needs a machine-readable brief it can act on directly within a payment workflow.

## Known failure modes

- Payment not included or insufficient — returns 402 with payment required headers
- Invalid HTTP method used (only GET/HEAD/DELETE accepted) — returns 405
- Service handler failure — ok: false with no brief returned
- Topic override not recognized — may return generic procedure without topic-specific content
- Network timeout on ascii.dev host — connection failure

## How this service works

Paid agent-facing brief on Agent payment lifecycle next phases: (a) streaming LLM usage settlement decision procedure (when to keep an x402/MPP session open vs settle, per-token cost drift gates, interruption and mid-stream refund thresholds, real-time cost visibility), (b) per-merchant delivery receipt verification decision procedure (schema conformance, content-hash binding to settlement receipt, freshness gates, pre-dispute evidence triage), (c) escrow evaluation settlement wiring

## Output

A JSON object containing a prose decision-procedure brief ('brief') covering streaming LLM settlement timing logic, per-merchant delivery receipt verification steps, and escrow settlement wiring, along with metadata: service slug, generation source (llm/reasoning/deterministic), topic, model identifier, and ISO-8601 generation timestamp. Payment confirmation fields (ok, paid) and provider info are also returned.
