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 a liquidity_change assessment string, a list of warnings, an evidence_scope indicator (e.g. 'caller_supplied_data'), and a status field. Also includes a full receipt with payment details, execution metadata, request/execution IDs, and a SHA-256 result hash for verification.
Example use cases
Flag suspicious DeFi pool withdrawal
“I'm watching a Uniswap v3 pool on Base and a large LP just pulled $6M in liquidity in one block — can you analyze that liquidity change and tell me if there are any red flags or warnings?”
Understand a protocol liquidity event
“Aave just had a significant liquidity removal event on Base. Here's what happened: 'Large USDC supplier withdrew 10M USDC, reducing available borrow liquidity by 45%.' Can you assess the liquidity change and summarize it for me?”
Research a DeFi position change
“I'm researching a Curve pool that added a new LP providing $2M in stablecoin liquidity yesterday, which pushed TVL up by 22%. Can you analyze this liquidity change and tell me what it might mean for slippage and pool health?”
Technical details
Endpoint
POSThttps://signalharness.ai/api/agent/services/defi_liquidity_change/invokeWhen to prefer
Choose this endpoint when you need a quick, structured AI-driven assessment of a described DeFi liquidity change event on Base or similar EVM chains, especially when you have free-text descriptions of pool events and want warnings or risk flags surfaced automatically. Prefer it over manual on-chain data queries when the liquidity event has already been observed and you need interpretation rather than raw data retrieval.
Side effects
- Input text too short (below 2 characters) or too long (above 65536 characters) returns validation error
- Ambiguous or insufficiently detailed liquidity change description may produce generic or low-confidence output
- Payment failure via x402 protocol results in 402 response and no analysis
- Service downtime returns non-200 status with no result object
- Malformed JSON request body causes request rejection
