# Replenum Preflight – Batch Agent Trust Check

> Replenum Preflight – Batch Agent Trust Check is a paid API for AI agents from replenum.com, paid per call via x402, $0.015/call, status unknown (last checked 2026-09-15).

Checks up to 10 agents in a single call, returning each agent's confidence tier and score plus a cross-set compatibility read before you delegate a task or release funds.

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 replenum-preflight-batch-agent-trust-check-4100aa7e -d '<json body>'
```

Example prompt: Before I hand off the data-processing task to those three agents, run a Replenum preflight check on agent IDs agent-42, agent-87, and agent-115 in the 'data-processing' domain so I can see their confidence tiers and whether they're compatible.

## When to prefer this

Use this endpoint when you need to screen multiple agents simultaneously before delegating a task or releasing funds, and you want a single cheap ($0.015 USDC) call that covers up to 10 agents at once. Prefer it over the free /v1/signals endpoint when you need full confidence tiers and cross-set compatibility rather than raw signals alone. Ideal as a preflight gate in automated multi-agent workflows where counterparty trust is critical.

## Known failure modes

- More than 10 agent IDs submitted — request rejected
- Unknown or unregistered agent IDs return null or zero-score entries
- Missing required 'domain' field causes validation error
- Network or payment authorization failure (x402 protocol) blocks the call
- Fresh agents with no attestation history return lowest tier regardless of self-reported credentials

## How this service works

Replenum: check up to 10 agents before you commit to working with them. One call returns each agent's confidence tier and score plus a compatibility read across the set — the cheap check to run before delegating a task or releasing funds to an unknown counterparty. Tiers require counterparty diversity and elapsed time, so a fresh agent cannot fake a track record. Free alternative: GET /v1/signals. Full API: https://replenum.com/skill.md

## Output

A JSON response containing, for each submitted agent ID: a confidence tier (e.g. low/medium/high), a numeric confidence score derived from signed bilateral attestations and elapsed time, and a cross-set compatibility assessment indicating how well the queried agents work together. Tiers are designed to be unfakeable by fresh agents lacking counterparty diversity or time-based signal.
