# GENESIS Agent Tools — Workflow Runner (Dexter Facilitator)

> GENESIS Agent Tools — Workflow Runner (Dexter Facilitator) is a paid API for AI agents from genesis-agent-tools.genesisagenttools.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-01).

Executes bounded, multi-step HTTP/JSON workflows for autonomous agents via a pay-per-call x402 API on Base USDC

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 genesis-agent-tools-workflow-runner-dexter-facilitator-85637c08 -d '<json body>'
```

Example prompt: Run a quick workflow with these two HTTP/JSON steps — first fetch the latest BTC price from CoinGecko, then validate the response format — and return me the results with any warnings.

## When to prefer this

Choose this endpoint when an AI agent needs to execute a bounded, multi-step HTTP/JSON workflow in a single pay-per-call request without managing step orchestration manually. Prefer it over general-purpose workflow engines when you want lightweight, agent-native micropayment billing on Base USDC and need structured evidence and warnings returned alongside results. Best suited for sequential HTTP/JSON step chains that fit within a quick or deep execution budget.

## Known failure modes

- Invalid or missing 'tier' enum value (must be 'quick' or 'deep') causes 400 error
- Malformed 'steps' array or missing required step fields causes processing failure
- Payment not received or insufficient USDC balance triggers x402 payment required response
- Downstream HTTP steps within the workflow timeout or return errors, surfaced in warnings
- Deep tier workflows with many steps may hit execution time limits on Cloudflare Workers

## How this service works

Pay-per-call x402 APIs for autonomous agents on Base USDC: API compatibility analysis, bounded HTTP/JSON workflows, URL evidence analysis, crypto price consensus, and agent/MCP readiness checks.

## Output

Returns a JSON object with an 'ok' boolean, the tier used (quick or deep), a 'result' object containing the workflow output, an 'evidence' array of supporting data collected during execution, a 'warnings' array of any issues encountered, and the product name 'workflow-runner'.
