# Settlement Timing

> Settlement Timing is a paid API for AI agents from k2so.wrong.systems, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-30).

Returns a live pay-now/wait/use-Base recommendation by combining Bitcoin mempool congestion data with current x402 Base transfer fees for microcharge settlement decisions.

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 settlement-timing-30fbe815
```

Example prompt: Before I submit this micropayment, check the current Bitcoin mempool congestion and Base x402 fee — should I pay right now, wait for cheaper fees, or switch to Base for settlement?

## When to prefer this

Choose this endpoint when an agent or user needs a real-time, opinionated recommendation on whether to settle a microcharge immediately via Bitcoin or Base x402, factoring in live mempool congestion and current Base transfer fees. It is particularly useful before committing to time-sensitive or cost-sensitive micropayments where the optimal settlement path is unclear. Prefer this over manually checking mempool.space or Base fee trackers separately when you need a single combined recommendation.

## Known failure modes

- Mempool data unavailable — upstream Bitcoin node or mempool API unreachable
- Base fee oracle offline — cannot retrieve current x402 transfer fee
- Payment not received — 402 response requiring x402 payment before data is returned
- Invalid query parameter for meta flag — must be '0' or '1'
- Service returns ok:false with handler error if internal logic fails

## How this service works

Live Bitcoin mempool congestion + 's measured Base x402 transfer fee, combined into a pay-now/wait/use-Base recommendation before a microcharge settles.

## Output

Returns a structured JSON object with an overall score, a summary recommendation (pay-now, wait, or use-Base), confidence level, evidence object with mempool and fee data, risk factors array, strengths array, and an ISO-8601 generatedAt timestamp. Includes a paid boolean and provider identification.
