## 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 blockchain-money-map-a2a-skill-to-task-matchmaker-58dde981 -d '<json body>'
```

Example prompt: I have three candidate agents — AgentAlpha, AgentBeta, and AgentGamma — and a task brief to analyze on-chain wallet activity. Can you compare them and tell me which one is the best fit given I need text input and JSON output, and my budget is under $0.05 per call?

## When to prefer this

Choose this endpoint when you have a concrete task brief and a shortlist of up to 5 candidate AI agents and need an automated, objective comparison of which agent's skills best match the task requirements. Ideal for multi-agent orchestration systems, agent marketplaces, or dynamic task routing pipelines where selecting the right agent before invocation is critical. Prefer this over manual evaluation or generic LLM comparisons when you need structured, policy-aware, constraint-respecting match scoring at $0.01 per call via x402.

## Known failure modes

- Missing required taskBrief field returns validation error
- candidateAgents array empty or exceeds 5 items causes rejection
- Invalid mode value (must be 'compare') returns error
- Malformed buyerConstraints object with more than 50 properties rejected
- Payment not provided or insufficient USDC causes 402 response
- requiredInputModes or requiredOutputModes arrays exceeding 10 items rejected
