# Policy Compile B — x402 Smart-Contract Policy Generator

> Policy Compile B — x402 Smart-Contract Policy Generator is a paid API for AI agents from the-stall.intuitek.ai, paid per call via x402, $0.2/call, status unknown (last checked 2026-09-14).

Compiles a jointly-signed policy document for an AI-deliverable job given a route class and plain-language job description, progressing from unsigned draft to fully countersigned policy hash.

## 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 policy-compile-b-x402-smart-contract-policy-generator-900ca49a
```

Example prompt: Compile a CODE route-class policy for a job described as 'build a REST API wrapper for a cryptocurrency price feed, deliverable within 5 days' — start with an unsigned draft first so I can review it before signing.

## When to prefer this

Choose this endpoint when you need a structured, on-chain-anchored policy document for an AI-deliverable job that requires mutual attestation from both client and provider — particularly when working across ENTITY, CONTRACTOR, CODE, FINANCIAL, or COMPOSITE job categories. Prefer it over generic document-generation tools when the workflow requires a two-step draft-then-countersign flow and the resulting policy_hash needs to be verifiable on Base mainnet.

## Known failure modes

- Missing required route_class or job_description returns a 400 validation error
- Invalid or unrecognized route_class enum value causes rejection
- Supplying a provider_sig on a first call (before client_sig is anchored) may produce an error or be ignored
- Payment not received (x402 flow incomplete) results in a 402 Payment Required response
- Mismatched route_class or job_description on the countersigning call causes hash mismatch and finalization failure

## How this service works

Domain-agnostic x402 capability chassis by IntuiTek¹. 300 AI-callable data services — pay USDC on Base mainnet. No accounts or API keys required.

## Output

Returns either an unsigned preview policy draft (when no client_sig is provided) or, when client_sig is supplied, a signed policy document; on a second call with a matching provider_sig, returns the finalized jointly-signed policy_hash binding both parties to the described deliverable.
