How this service works
Base chain + x402 protocol constants
Output
Returns a JSON object containing Base chain network constants and x402 protocol metadata, including protocol version, list of supported chains, available protocol features, and the seller address used for payment routing.
Example use cases
Bootstrap x402 payment integration
“What are the x402 protocol constants I need to integrate payments with the Compute API — specifically the protocol version, supported chains, and seller address?”
Verify Base chain compatibility
“Can you pull the Base chain and x402 configuration from the Compute API so I can check which chains and features are supported before I start building?”
Audit protocol configuration
“Fetch the current x402 protocol version and network constants from the Compute API so I can confirm the setup matches what my app expects.”
Technical details
Endpoint
GEThttps://compute-api-production-245d.up.railway.app/constants?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically discover or verify the x402 protocol configuration and Base chain constants for the Compute API — particularly useful during initial integration, configuration validation, or when building payment flows that depend on knowing the correct seller address, supported chains, or protocol version.
Side effects
- Service unavailable (Railway deployment down) — 502/503 error
- Unexpected schema change if protocol version updates break consumers
- Rate limiting or payment failure ($0.01 USDC not paid) returns 402 Payment Required
- Empty or partial response if the Railway instance is cold-starting
