This specific endpoint decomposes a protocol's Total Value Locked (TVL) by chain, allowing callers to understand how a protocol's liquidity is distributed across different blockchains. It is priced at $0.50 per call, paid in USDC on Base via the x402 protocol.\n\nDeFi Shield covers 11 categories including DeFi intelligence, wallet profiling, MEV analysis, NFT risk, cross-chain comparisons, and more. All endpoints follow the same pattern: POST requests with an x402 payment header containing a USDC payment token. Free GET requests to any endpoint path return discovery metadata including an `llm_usage_prompt` for agent integration. The service also exposes a health endpoint (`/api/health`) listing all endpoints and pricing, an analytics endpoint (`/api/analytics`), and an A2A discovery card at `/.well-known/agent-card.json`.\n\nThe TVL decompose endpoint sits within the Protocol Intelligence category alongside related endpoints for protocol risk scoring, governance centralization analysis, multi-protocol comparison, token emission modeling, oracle dependency risk, and bridge risk assessment. No OpenAPI schema or detailed request/response documentation was found during crawling, so the exact request parameters and response format must be inferred from the endpoint's purpose and the platform's general patterns.","tags":[],"capabilities":["tvl-decomposition","protocol-analytics","defi-intelligence","x402-payment","usdc-base-settlement","per-request-pricing","agent-discoverable","cross-chain-tvl"],"categories":["defi","blockchain-analytics"],"synonyms":["total value locked breakdown","TVL by chain","protocol TVL analysis","DeFi protocol liquidity","chain TVL distribution","TVL decomposition","protocol chain breakdown"],"warnings":["No OpenAPI or JSON schema available for request or response validation","No dedicated docs page found (returns 404)","Request body parameters are inferred — actual required fields may differ","x402 challenge returned empty object, so payment details (amount, asset, network) could not be independently verified from the probe","Response format is entirely unknown — example_response_json is null"],"endpointUrl":"https://defi-shield-hazel.vercel.app/api/protocol/tvl-decompose","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x0814d35F25F2EF3Dffa4aEF4d137558D5E51Ed7b","amount":"500000","scheme":"exact","network":"eip155:8453","maxTimeoutSeconds":300}]},"qualityScore":"0.450","qualityRationale":"The endpoint is live (402 challenge confirmed) and the landing page provides clear pricing and category context, but no OpenAPI schema, detailed parameter documentation, or example responses were found.
