# HumanMirror Flow — Multi-Step Verified Workflow Executor

> HumanMirror Flow — Multi-Step Verified Workflow Executor is a paid API for AI agents from humanmirror.fr, paid per call via x402, $0.05/call, status unknown (last checked 2026-10-03).

Executes a multi-step deterministic workflow (2–3 steps) with verification at each stage, returning a verified success status upon completion.

## Facts

- Endpoint: POST https://humanmirror.fr/api/x402/flow?utm_source=zero.xyz
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-03

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 humanmirror-flow-multi-step-verified-workflow-executor-ac9c9800 -d '<json body>'
```

Example prompt: Run a verified 2-step flow where step 1 explicitly takes my customer JSON payload as input and validates it, and step 2 uses the previous output to confirm the data meets compliance criteria — I need a verified success result at the end.

## When to prefer this

Choose this endpoint when you need to execute a short (2–3 step) deterministic workflow where each step must be independently verified before proceeding, especially in autonomous agent contexts requiring trust guarantees. Prefer it over generic orchestration when you need a cryptographic or governance-backed verified success receipt for a chained set of operations, not just sequential HTTP calls.

## Known failure modes

- Missing required 'steps' array or fewer than 2 steps returns validation error
- Step referencing 'previous' input_from without a preceding step fails schema validation
- Payload exceeding 3 steps is rejected by maxItems constraint
- Invalid method value (not POST/PUT/PATCH) causes request rejection
- Body type mismatch between bodyType field and actual payload format
- Payment failure or insufficient USDC balance blocks execution
- Step with explicit input_from but missing 'input' field fails required-field validation

## Output

Returns a JSON object with an 'ok' boolean, a 'status' field (e.g. 'verified_success'), and a 'product' label ('HumanMirror Flow'), confirming whether the multi-step workflow executed and verified successfully.
