## 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 condition-triggered-payment-release-verification-for-agent-escrow-17588f42
```

Example prompt: Before my agent accepts the escrow payment release triggered by condition X, give me the blunt decision procedure — should it accept-release, verify-before-accept, or refuse-release-with-evidence for this situation?

## When to prefer this

Choose this endpoint when an autonomous agent needs a structured, opinionated decision procedure specifically for verifying condition-triggered escrow releases in programmable money contexts — particularly on Base/USDC with x402 payment flows. Prefer over general legal or contract review tools when the agent needs machine-readable verdicts (accept/verify/refuse) rather than human-readable summaries. Best suited for agents operating in multi-agent marketplaces, on-chain task completion workflows, or any scenario where a smart contract automatically releases funds on a condition.

## Known failure modes

- Payment not provided or insufficient USDC — returns 402 Payment Required
- Invalid query parameters cause schema validation failure
- LLM generation failure may result in ok:false in the result object
- Network or provider downtime returns a server error
- Topic override too vague may produce a generic rather than targeted procedure

## How this service works

Decision procedure for agents paying through escrow or programmable-money contracts that release funds when condition X is met. The release proves the contract executed, not that the work behind X happened or that the right party did it. Covers: classifying the condition type (on-chain oracle, attestation, counterparty claim, deliverable hash), checking who asserted X and whether that source is independent of the payee, verifying work evidence before accepting the release, the

## Output

A paid JSON response containing a prose decision brief ('brief'), a structured decision procedure, a verdict category (accept-release, verify-before-accept, or refuse-release-with-evidence), the topic, generation source (llm/reasoning/deterministic), and an ISO-8601 timestamp of generation. Also includes payment metadata confirming the x402 micropayment was processed.
