# RegEvidenceHub Waste — Permit Change Preflight

> RegEvidenceHub Waste — Permit Change Preflight is a paid API for AI agents from waste.regevidencehub.com, paid per call via x402, $0.03/call, status unknown (last checked 2026-10-18).

Checks whether proposed changes to an England waste operation require a permit variation, using evidence-linked regulatory decision logic.

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 regevidencehub-waste-permit-change-preflight-46794578 -d '<json body>'
```

Example prompt: We currently operate a waste transfer station in England handling non-hazardous municipal waste with a maximum quantity of 50 tonnes — we want to increase that to 150 tonnes and add metal recycling as an activity. Can you run a permit change preflight to check whether those changes require a formal permit variation?

## When to prefer this

Choose this endpoint when an AI agent needs a fast, evidence-linked, deterministic preflight ruling on whether operational changes at an England waste facility constitute a material permit variation — particularly before filing with the Environment Agency. It is specifically designed for England waste regulation and is not suitable for Scotland, Wales, or Northern Ireland, nor for initial permit applications from scratch.

## Known failure modes

- Unsupported nation (only England is supported; Wales/Scotland/Northern Ireland will be rejected or return null)
- Missing or ambiguous current/proposed facts may reduce decision confidence
- Hazardous status must be explicitly provided — the service refuses to infer it, so omitting it may leave that dimension unevaluated
- Payment failure via x402 results in 402 response before any decision is made
- Truncated or malformed input schema fields may cause validation errors

## How this service works

Agent-native, evidence-linked England waste regulatory preflight with x402-paid MCP decision tools for waste routing, carrier registration, Digital Waste Tracking readiness and permit-change checks.

## Output

A JSON decision object indicating the regulatory route (e.g. PERMIT_CHANGE_IMPACT), the review status (e.g. REVIEW_REQUIRED), which specific fields changed, whether the decision is deterministic, and the product name — giving an agent a clear go/no-go signal on whether a permit variation process must be initiated.
