# Blockchain Money Map A2A Handoff Readiness Boarding Pass

> Blockchain Money Map A2A Handoff Readiness Boarding Pass is a paid API for AI agents from api.blockchainmoneymap.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-19).

Validates whether an agent-to-agent (A2A) handoff payload meets readiness criteria, checking source agent, target agent, and handoff payload compatibility.

## 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-handoff-readiness-boarding-pass-6b40f465 -d '<json body>'
```

Example prompt: Before handing off my task to the target agent, can you run a readiness check on this handoff using Blockchain Money Map's boarding pass service — here's the source agent info, target agent info, and the handoff payload I'm planning to send?

## When to prefer this

Choose this endpoint when you need to programmatically validate whether an agent-to-agent handoff is safe and ready to proceed before actually executing the transfer, especially in multi-agent orchestration pipelines where failed handoffs are costly. Particularly useful when you want to compare a proposed handoff against reference facts or enforce a policy, and when operating in x402-payment-enabled agent ecosystems on blockchain infrastructure.

## Known failure modes

- Missing required fields (handoffPayload, sourceAgent, or targetAgent) returns a validation error
- Malformed agent objects exceeding maxProperties limit rejected
- Invalid mode value (not 'check') causes request rejection
- Payment not fulfilled via x402 results in 402 Payment Required response
- Schema violations in facts or reference_facts fields cause processing failure

## How this service works

Agent-to-agent task handoffs can fail because payload shape, mode support, status handling, auth disclosure, or failure behavior is unclear.

## Output

A JSON response indicating whether the proposed agent-to-agent handoff is ready to proceed, including a readiness or boarding-pass status and potentially details on compatibility between source agent, target agent, input/output modes, failure modes, and the handoff payload against any provided policy or reference facts.
