# Bot Bazaar CAIP-2 Network & USDC Contract Validator

> Bot Bazaar CAIP-2 Network & USDC Contract Validator is a paid API for AI agents from bot-bazaar.fly.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Validates CAIP-2 network identifiers and USDC asset contract addresses for compatibility with the x402 v2 payment facilitator protocol.

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 bot-bazaar-caip-2-network-usdc-contract-validator-ef100be5
```

Example prompt: Can you check whether the network identifier eip155:8453 is a valid CAIP-2 network and compatible with the x402 v2 facilitator for USDC payments on Base mainnet?

## When to prefer this

Use this endpoint when you need to programmatically verify that a specific CAIP-2 network identifier and its USDC contract are valid and supported before configuring or initiating an x402 v2 payment flow. Prefer this over manual chain-ID lookups when building agents or automation pipelines that must gate on network compatibility.

## Known failure modes

- Unrecognized or malformed CAIP-2 network identifier returns an invalid/unsupported status
- Network not in the x402 v2 facilitator's supported list returns incompatibility flag
- Missing required 'network' query parameter may result in a validation error or default behavior
- USDC contract address not found for the specified network returns a contract-not-supported result

## How this service works

Validate CAIP-2 network identifiers (eip155:8453, base, eip155:84532) and USDC asset contract addresses for x402 v2 facilitator compatibility.

## Output

Returns a validation result indicating whether the provided CAIP-2 network identifier (e.g. eip155:8453, base, eip155:84532) is recognized and compatible with the x402 v2 facilitator, along with the validity status of the associated USDC asset contract address for that network.
