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.
Example use cases
Pre-deployment x402 network check
“Before I launch my x402 payment integration, can you verify that eip155:8453 is a valid CAIP-2 network identifier and that it's supported by the x402 v2 facilitator?”
Testnet compatibility validation
“I'm building on Base Sepolia — can you check if eip155:84532 is a recognized CAIP-2 network identifier and works with the x402 v2 facilitator for USDC?”
Shorthand alias network check
“Does the network alias 'base' count as a valid CAIP-2 network ID that the x402 v2 facilitator will accept, or do I need to use the full eip155:8453 format?”
Technical details
Endpoint
GEThttps://bot-bazaar.fly.dev/v1/x402/caip2-network-check?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
