How this service works
Keyless attested data for autonomous agents. USDC on Base via x402. Official @x402/* middleware.
Output
A JSON object containing at minimum an asset_id string and a resolved boolean indicating whether the domain intelligence lookup succeeded, along with any additional attested metadata associated with that asset identifier.
Example use cases
Verify asset resolution before trading
“Before I execute a swap, can you check if the asset ID 'WETH' resolves correctly in LION's domain intel service and confirm the attestation looks valid?”
Enrich agent pipeline with asset metadata
“My agent pipeline needs verified domain intel for the asset 'USDC' — can you pull the attested JSON from LION and include the resolved status in the report?”
Audit unknown token domain data
“I've got a token with asset ID 'XYZ42' and I'm not sure if it's legitimate — can you query the LION domain intelligence endpoint and tell me what it returns about that asset?”
Technical details
Endpoint
GEThttps://lion-x402-bible.lionmaster-operations.workers.dev/api/x402/domain-intel-jsonWhen to prefer
Choose this endpoint when you need keyless, cryptographically attested domain intelligence for a specific asset ID on Base, and your agent supports x402 micropayment flow with USDC. Prefer this over generic blockchain explorers when you need structured JSON attestation data rather than raw on-chain state, and when you want a pay-per-query model without API key management.
Side effects
- Payment failure: x402 micropayment not processed or insufficient USDC balance — endpoint returns 402 Payment Required
- Invalid asset_id: unknown or malformed identifier returns resolved: false or an error object
- Network/worker failure: Cloudflare Worker unavailable returns 503 or timeout
- Rate limiting: excessive requests may be throttled by the worker
- Missing parameter: no asset_id provided may return a 400 Bad Request
