# Base DeFi Dependents by Entity

> Base DeFi Dependents by Entity is a paid API for AI agents from intel.fintechhodl.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-29).

Returns all tracked Base DeFi yield opportunities that depend on a given entity (protocol, stablecoin, oracle, or curator), along with their total TVL, for exploit/depeg/oracle failure impact sizing.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 base-defi-dependents-by-entity-51ccd6ff
```

Example prompt: What Base DeFi yield opportunities depend on protocol:morpho-blue, and what's the total TVL at risk if it gets exploited?

## When to prefer this

Use this endpoint when you need to identify all yield opportunities on Base that transitively depend on a specific protocol, stablecoin, oracle, or curator — especially for sizing exploit risk, depeg contagion, or oracle failure impact. Prefer this over the full opportunity list when you have a specific entity in mind and want to focus analysis on its downstream dependents.

## Known failure modes

- 404 if the entity id is unknown or not tracked
- 400 if the entity id format is invalid (must match pattern ^[A-Za-z0-9:._#+-]{1,120}$)
- 503 while underlying data is refreshing (no charge on 503)
- No charge unless a 200 is returned

## How this service works

Which tracked Base opportunities depend on an entity (protocol, stablecoin, oracle, curator), with their total TVL. Useful for sizing the impact of an exploit, depeg or oracle failure. Entity ids appear in dependency graphs, for example protocol:morpho-blue. Unknown ids answer 404 and invalid arguments 400 before any payment; 503 while data refreshes; charged only for a 200.

## Output

A JSON object containing the entity's id/type/name, a timestamp of when the data was valid, the model version used, a count of dependent opportunities, the sum of their TVL in USD, and an array of opportunity objects each describing the yield pool or vault that depends on the queried entity. Also includes a disclaimer and data freshness indicator in minutes.
