# Vealth Ecological Work Packet Builder

> Vealth Ecological Work Packet Builder is a paid API for AI agents from vealth.net, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Takes a place and ecological problem as input and returns a fully bounded ecological work packet including matched standard definition, method, proof requirements, tCO2e estimate, and on-chain funding/settlement path.

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 vealth-ecological-work-packet-builder-85546e92 -d '<json body>'
```

Example prompt: Build me an ecological work packet for addressing topsoil degradation in the Sahel region of Niger — I need the matched standard, method, proof requirements, tCO2e estimate, and funding path.

## When to prefer this

Choose this endpoint when you need a deterministic, standards-registered ecological work packet — not an LLM-generated suggestion — complete with tCO2e accounting and a concrete on-chain funding/settlement path. Prefer this over general carbon calculators or advisory tools when you need structured proof requirements and a method aligned to registered ecological standards for a specific place and problem.

## Known failure modes

- Unrecognized place string may return no matched work definition
- Vague or unmapped problem description may fail to match a registered standard
- Missing required 'place' or 'problem' fields returns a 400 validation error
- Payment failure via x402 protocol returns 402 Payment Required
- Ecological problem outside the registered library scope returns empty or null work packet

## How this service works

Work Packet Builder (CDP-settled mirror of /.well-known/vealth/work-packet) — place + problem in, bounded ecological work packet out: matched definition from the standards-registered ecological work library, method, proof requirements, tCO2e estimate, funding + on-chain settlement path. Deterministic, no LLM.

## Output

Returns a fully bounded ecological work packet containing: a matched definition from the standards-registered ecological work library, the applicable method, required proof submissions, a tCO2e estimate, and a funding plus on-chain (CDP) settlement path. Deterministic output with no LLM inference.
