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 agentstools-cloud-cost-estimator-ec7c3c1d -d '<json body>'
```

Example prompt: Before I run terraform apply, estimate the monthly AWS cost for this Terraform plan JSON and check it against a $300/month budget — give me the total, a per-resource breakdown, and tell me if it passes, needs caution, or should be blocked.

## When to prefer this

Choose this endpoint when you need a cost estimate before deploying infrastructure-as-code (Terraform, CloudFormation, docker-compose) to AWS or Azure, especially when enforcing budget gates in a CI/CD pipeline or agentic workflow. Prefer this over manual cost-calculator tools when you need programmatic, per-resource breakdowns with FinOps policy verdicts integrated into an automated decision loop.

## Known failure modes

- Unsupported resource types not priced (returned with zero or unknown cost)
- Malformed or unparseable IaC config returns an error
- Azure/AWS resources outside supported set may be omitted from estimate
- Budget verdict only returned when budget parameter is supplied
- Estimate may differ from actual bill due to usage-based pricing assumptions

## How this service works

Estimate the monthly cloud cost of an infrastructure-as-code config before you apply it: Terraform (plan JSON or HCL), CloudFormation or docker-compose. Returns total monthly USD, a per-resource breakdown (unit price, quantity, assumptions), FinOps policy findings and a budget verdict (pass, caution, block) against an optional monthly budget. AWS and Azure common resources. Cost estimate, not a bill.

## Output

Returns total estimated monthly USD cost, a per-resource breakdown including unit price, quantity, and assumptions made, FinOps policy findings highlighting potential waste or risk, and a budget verdict (pass, caution, or block) compared against an optional monthly budget ceiling. Covers common AWS and Azure resource types.
