# LOR Base Lending Evaluator

> LOR Base Lending Evaluator is a paid API for AI agents from api.alphabuild.xyz, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Evaluates whether a requested USDC supply amount is realizable across Aave V3 and Morpho Blue lending opportunities on Base, with optional APY and protocol filters.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability lor-base-lending-evaluator-1aad8966 -d '<json body>'
```

Example prompt: Can you check whether I can supply 5000 USDC on Base — look across both Aave V3 and Morpho Blue and only show me opportunities with at least a 4% base supply APY?

## When to prefer this

Choose this endpoint when you need to programmatically evaluate whether a specific USDC supply amount can be placed into DeFi lending on Base before committing to a transaction — particularly when you want to filter by minimum APY or specific protocol (Aave V3 or Morpho Blue). Prefer this over generic DeFi aggregators when you need a structured, agent-callable feasibility check with deterministic schema output, or when orchestrating automated yield strategies on Base.

## Known failure modes

- No opportunities meet the minimum_base_supply_apy threshold — returns empty or rejected result
- Requested amount exceeds available liquidity in matched protocols — marked as not realizable
- Invalid or unsupported opportunity_id provided without a protocol — validation error
- Amount provided in atomic units instead of whole-token decimals — incorrect evaluation
- protocol filter set to unsupported value — schema validation failure
- Network unavailable or Base RPC issues — timeout or service error

## How this service works

Evaluate whether a requested USDC supply amount is realizable across approved Aave V3 and Morpho Blue lending opportunities on Base, with optional minimum supply APY and protocol filters.

## Output

Returns an assessment of whether the requested USDC supply amount is realizable across approved Aave V3 and/or Morpho Blue lending opportunities on Base (chain ID 8453), including matched opportunities, their base supply APYs, and feasibility status given the requested amount and any APY or protocol filters applied.
