# Agent Credit-Line Utilization and Evaluation-Based Settlement Procedure

> Agent Credit-Line Utilization and Evaluation-Based Settlement 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 deterministic decision procedure for agents managing credit-line draws, utilization tracking, top-up warnings, and evaluation-verdict-based escrow settlement via x402.

## 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-credit-line-utilization-and-evaluation-based-settlement-procedure-1dad9755
```

Example prompt: I need to know which credit line to draw this $0.85 payment from — line A is at 68% utilization with a $10 cap, line B is at 40% with a $5 cap — the delivered work got a partial-pass evaluation verdict, so what's the prorated settlement amount and do I need to flag a top-up?

## When to prefer this

Choose this endpoint when an agent must simultaneously decide which credit line to use for an x402 payment AND reconcile escrow settlement against evaluation verdicts in a single deterministic procedure. It is specifically suited for multi-line credit scenarios with utilization thresholds and evaluation-gated escrow release, rather than simple single-payment routing or generic budget checks.

## Known failure modes

- Missing required credit-line caps or utilization values — returns ok: false with handler error
- Payment amount exceeds all available credit lines below hard ceiling — procedure flags no viable line
- Invalid or missing evaluation verdict — settlement calculation cannot be completed
- Service unavailable or unpaid request — returns 402 Payment Required
- Malformed query parameters — schema validation failure

## How this service works

Deterministic procedure for agents that pay from credit lines and escrow balances via x402. Inputs: per-line caps and rates, current utilization, payment amount, due date, evaluation verdicts on delivered work, escrow state. Decides which line a payment draws against, tracks utilization after draw, flags top-up when utilization crosses 70% warning and 95% hard ceiling, wires evaluation verdicts into settlement: full pass releases, fail reduces settlement by defined ratio, partial pass prorates.

## Output

Returns a structured procedure result including a decision brief (prose for agents), the chosen credit line, post-draw utilization, any top-up warning flags (70% or 95% thresholds), and the settlement amount adjusted by evaluation verdict (full release, prorated partial, or reduced fail ratio), plus a timestamp and generation source.
