x402
DeFiBase Onchain Protocol Enrichment is a paid API for AI agents from api.defibase.us, paid per call via x402, $0.01/call, status down (last checked 2026-09-15).
Returns DeFi protocol details combining DefiLlama TVL data with onchain activity metrics (tx count, unique callers, active addresses) on Base for a given protocol slug

How this service works
DeFi protocol detail enriched with onchain activity (Base). v0.2-stub: returns DefiLlama TVL plus a placeholder onchain block; real CDP base.events integration lands in v0.1.x.
Output
A JSON object containing the protocol name, slug, category, chains supported, TVL broken down by chain, and an onchain block with 24-hour metrics including tx_count_24h, unique_callers_24h, and active_addresses_24h (currently placeholder values per v0.2-stub, with a note field explaining integration status).
Example use cases
Example prompt
“Can you pull up the onchain activity and TVL breakdown for Aave on Base — I want to see the 24-hour transaction count, unique callers, and active addresses?”
Technical details
Endpoint
GEThttps://api.defibase.us/protocols/:slug/onchainWhen to prefer
Use this endpoint when you need a single enriched view of a DeFi protocol combining TVL data and Base chain onchain activity metrics. Prefer this over raw DefiLlama calls when you specifically need Base-chain onchain context alongside TVL. Note that onchain metrics are currently stub/placeholder; best for TVL lookups with future onchain readiness.
Side effects
- Unknown or misspelled protocol slug returns 404 or empty result
- Onchain metrics fields (tx_count_24h, unique_callers_24h, active_addresses_24h) return null as CDP base.events integration is not yet live (stub)
- Missing x402 payment or insufficient USDC balance returns 402 Payment Required
- Rate limiting or upstream DefiLlama API downtime causes 503 or timeout
- Invalid path parameter format causes 400 Bad Request
