GET /v1/crypto/protocol

live

Deep dive on any DeFi protocol by its DefiLlama slug (aave-v3, lido, uniswap…): current Total Value Locked, market cap, category, the chains it spans, a per-chain TVL breakdown, and a 30-day TVL history. Everything you need to size up a protocol in one call. Sourced from DefiLlama.

Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
