How this service works
Barker's stablecoin market snapshot: total market cap, yield-bearing cap, asset distribution, chain distribution. Use for 'stablecoin market cap', 'USDT market share', '稳定币市场份额'. share_pct fields are decimals (0.425 = 42.5%).
Output
A structured JSON snapshot containing: total stablecoin market cap, yield-bearing stablecoin market cap, asset distribution (e.g. USDT, USDC, DAI share as decimals), and chain distribution (e.g. Ethereum, Tron, Solana share as decimals). Share percentages are expressed as decimals where 0.425 = 42.5%.
Example use cases
Daily stablecoin market briefing
“Pull up today's stablecoin market overview — I want to see the total market cap, the yield-bearing portion, and which assets and chains hold the biggest share.”
USDT vs USDC dominance check
“What does the current stablecoin asset distribution look like? I'm trying to compare USDT and USDC market share against the rest of the field.”
Yield-bearing stablecoin market sizing
“How much of the total stablecoin market cap is currently sitting in yield-bearing products? I want the absolute number and the percentage.”

Endpoint
GEThttps://mcp.barker.money/barker_market_overviewWhen to prefer
Use this endpoint when you need a high-level, aggregated view of the stablecoin market — total cap, yield-bearing cap, and distribution by asset or chain — rather than per-pool or per-protocol data. Prefer this over sibling endpoints when the user asks about market-wide statistics, dominance, or macro stablecoin trends rather than specific yield pools or execution routes.
Side effects
- Data temporarily unavailable if upstream on-chain indexing is stale
- Payment failure (402) if the x402 micropayment of $0.001 USDC is not provided
- Malformed response if the endpoint is under maintenance
- Rate limiting if called too frequently without valid payment headers
