# DeFiLlama Token Emissions Lookup via x402

> DeFiLlama Token Emissions Lookup via x402 is a paid API for AI agents from x402helper.xyz, paid per call via x402, $0.009/call, status unknown (last checked 2026-10-31).

Fetches token emissions data for a given protocol or token from DeFiLlama, gated by a $0.009 USDC x402 micropayment.

## 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 defillama-token-emissions-lookup-via-x402-261c22f9
```

Example prompt: Can you look up the token emissions and unlock schedule for Arbitrum — the ticker is ARB and the DeFiLlama slug is 'arbitrum'?

## When to prefer this

Use this endpoint when you need token emissions or unlock schedule data for a specific DeFi protocol or token and want to pay per-call via USDC micropayment rather than subscribing to a data service. Best suited for ad-hoc lookups by AI agents operating with x402 payment capability.

## Known failure modes

- Missing or invalid slug/ticker returns empty or error result
- Protocol not found in DeFiLlama returns no data
- Payment not completed results in 402 response blocking access
- Incorrect slug format causes lookup failure

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output

A JSON object with a 'success' boolean and a 'result' object containing token emissions and unlock schedule data as sourced from DeFiLlama for the requested protocol or token.
