# Blockchain Money Map x402 Multi-Chain Facilitator Failover Planner

> Blockchain Money Map x402 Multi-Chain Facilitator Failover Planner is a paid API for AI agents from api.blockchainmoneymap.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-13).

Analyzes x402 multi-chain payment facilitator configurations to produce failover and fallback planning recommendations across blockchain networks.

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 blockchain-money-map-x402-multi-chain-facilitator-failover-planner-d8eebfcb -d '<json body>'
```

Example prompt: Analyze my x402 facilitator failover setup: primary facilitator is 'facilitator.coinbase.com', secondary is 'facilitator.example.com', allowed networks are ['base', 'ethereum'], fallback policy is 'switch to secondary on timeout', and I have duplicate settlement caution enabled — tell me if this configuration is sound.

## When to prefer this

Choose this endpoint when you need to programmatically evaluate or plan failover strategies for x402 multi-chain payment facilitator configurations — especially when comparing primary vs secondary facilitators, auditing allowed networks, or validating settlement and fallback policies before deployment. It is purpose-built for x402 infrastructure planning rather than general blockchain analytics.

## Known failure modes

- Missing required fields (primary_facilitator, allowed_networks, fallback_policy) returns validation error
- Invalid mode value (not 'analyze') returns schema rejection
- allowed_networks array exceeds 50 items returns error
- fallback_policy or settlement_caveats exceeds 500 character limit returns truncation or error
- Malformed JSON body returns 400 Bad Request
- Payment not provided or invalid results in 402 Payment Required

## How this service works

## Output

Returns a JSON analysis of the provided x402 facilitator failover configuration, including assessment of fallback policy soundness, network coverage, settlement risk, duplicate settlement caution, and recommendations for improving resilience or resolving conflicts between primary and secondary facilitator settings.
