## 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 quantaflow-abstract-rates-endpoint-5c17e2d1 -d '<json body>'
```

Example prompt: Can you pull the current rates from the Abstract DeFi protocol — I need the latest pricing data for my web3 dashboard and I'm okay with the $0.01 USDC per-call fee.

## When to prefer this

Choose this endpoint when you need current rates or pricing data from the Abstract DeFi/web3 protocol and are operating in an x402-capable environment where USDC micropayments ($0.01 per call) are acceptable. Prefer this over direct upstream calls when you want a standardized x402 payment-gated proxy that handles web3 authentication flows, or when building agents that need pay-per-call DeFi data access without maintaining upstream API keys.

## Known failure modes

- Payment failure — insufficient USDC balance or wallet not configured for x402 micropayments returns 402 Payment Required
- Invalid path — incorrect path segment below the upstream origin returns an upstream 404 or gateway error
- Malformed query object — incorrect query parameter formatting may cause upstream errors
- Upstream unavailability — if the Abstract rates upstream is down, the gateway passes through the upstream error
- Rate limiting — excessive calls may trigger upstream or gateway rate limits

## How this service works

Every request, a quantum of value. x402 protocol-based payment endpoint for web3/DeFi tools.

## Output

The upstream Abstract rates API response is passed through verbatim after successful x402 micropayment authorization, returning rates data (prices, exchange rates, or protocol-specific DeFi metrics) as JSON along with the upstream content type.
