How this service works
Explore 330 pay-per-call x402 API services and 27 agent-native digital products, with Base USDC pricing, secure Polar checkout, and free discovery.
Output
Returns a JSON object containing the computed liquidity_share value, any warnings about data quality or assumptions, the evidence_scope indicating the data source was caller-supplied, and a full execution receipt including payment metadata, latency, and a SHA-256 result hash for verification.
Example use cases
LP share calculation for AMM position
“I just added 10,000 USDC and 5 ETH to a liquidity pool that has total reserves of 2,000,000 USDC and 1000 ETH — can you figure out what percentage share of that pool I own?”
DeFi portfolio rebalancing decision
“I need to know my current liquidity share across my Curve Finance position before I decide whether to add more funds — here's my position: 50,000 DAI deposited into a pool with 5,000,000 DAI total liquidity. What's my share?”
Yield farming share audit
“Can you compute the liquidity share for this farming position I'm evaluating: someone put in 200 WBTC into a pool with 8,000 WBTC total. I need to know their ownership percentage to estimate yield.”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/defi_liquidity_share/invokeWhen to prefer
Use this endpoint when you need a quick, pay-per-call computation of a DeFi liquidity share without maintaining a persistent connection to a blockchain node or indexer. It is suitable for agents that need on-demand LP share estimates from caller-supplied data at low cost ($0.005 USDC), especially when integrating with x402-compatible micropayment flows on Base.
Side effects
- Invalid or malformed liquidity_share_request string returns an error
- Missing required liquidity_share_request field causes a validation failure
- Request string too short (under 2 chars) or too long (over 65536 chars) is rejected
- Ambiguous or insufficient pool data may result in warnings rather than a precise figure
- Payment failure via x402 protocol causes the call to be rejected before execution
