# GENESIS Agent Tools — Bounded HTTP/JSON Workflow Runner (Dexter Facilitator)

> GENESIS Agent Tools — Bounded HTTP/JSON 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 a bounded, multi-step HTTP/JSON workflow for autonomous agents, accepting a sequence of steps and returning structured results with evidence and warnings.

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-bounded-http-json-workflow-runner-dexter-29f47e98 -d '<json body>'
```

Example prompt: Run a quick bounded HTTP/JSON workflow for me with these two steps: first fetch the current ETH price from CoinGecko, then post that value to my webhook at https://my-server.example.com/ingest — I need the result object and any warnings back.

## When to prefer this

Choose this endpoint when an autonomous agent needs to execute a predefined, bounded sequence of HTTP/JSON calls in a single pay-per-call operation rather than orchestrating each step individually. It is especially useful when the agent needs combined evidence and warnings across steps, wants to minimize round-trips, or is operating within a pay-per-use x402 payment framework on Base USDC. Prefer alternatives if you need fully unbounded web crawling, database writes, or non-HTTP workflow steps.

## Known failure modes

- Invalid or empty steps array returns a validation error
- Upstream HTTP endpoints in workflow steps are unreachable or return errors
- Payment not completed (x402) causes 402 response before workflow runs
- Malformed step definitions cause workflow parsing failure
- Tier enum value outside 'quick'/'deep' causes rejection
- Deep tier workflows may time out on Cloudflare Workers execution limits

## 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 ok (boolean), tier (quick or deep), result (the aggregated workflow output object), product name ('workflow-runner'), an evidence array containing intermediate results or supporting data, and a warnings array for any issues encountered during execution.
