# Bounty Engineer Agent Commerce API – Tool Call Dry Run

> Bounty Engineer Agent Commerce API – Tool Call Dry Run is a paid API for AI agents from bounty-engineer-x402-prod.onrender.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-10).

Pre-validates an agent tool call against spend controls, policy rules, and safety guards before actual execution, returning an allow/deny decision with findings.

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 bounty-engineer-agent-commerce-api-tool-call-dry-run-6db00040 -d '<json body>'
```

Example prompt: Before I execute this tool call to the GitHub bounty search tool with these arguments, run a dry run guard check on it to make sure it passes spend controls and won't be blocked.

## When to prefer this

Use this endpoint when an autonomous agent needs to pre-validate a tool call before committing to execution and payment — especially when enforcing spend controls, margin policies, or safety guards. Prefer this over direct tool invocation when the cost of a failed or policy-violating call is non-trivial, or when you need an audit trail of pre-execution decisions.

## Known failure modes

- Missing or malformed tool_name causes validation failure
- Invalid schema object format returns error
- Arguments that don't match schema shape may yield unexpected findings
- Payment not attached results in 402 response before validation occurs
- Tool name not recognized may result in deny decision with unknown tool finding

## How this service works

Machine-buyable infrastructure for autonomous agents: API cost routing, margin optimization, funding-rate data, webpage extraction, result verification, spend controls, retry planning, state, tender search and GitHub bounty intelligence.

## Output

Returns a JSON object with an 'ok' boolean, a 'mode' field set to 'tool_call_dry_run_guard', a 'decision' of 'allow' or 'deny', and a 'findings' array listing any policy violations or concerns detected during pre-validation.
