# Straelo Relay DeFi Execution Snapshot

> Straelo Relay DeFi Execution Snapshot is a paid API for AI agents from relay.straelo.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-11).

Fetches and compares read-only Base chain swap quotes from 1inch and KyberSwap, returning normalized outputs, consensus metrics, price dispersion, and provider limitations without executing any trade.

## 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 straelo-relay-defi-execution-snapshot-e7958620 -d '<json body>'
```

Example prompt: Compare swap quotes from 1inch and KyberSwap on Base for swapping 1000 USDC to ETH with 50 basis points slippage, using 1inch as the baseline provider, and tell me the consensus price, dispersion, and which aggregator gives the better deal — without executing the trade.

## When to prefer this

Use this endpoint when you need a side-by-side, normalized comparison of swap quotes from both 1inch and KyberSwap on Base before committing to a trade. It is ideal for pre-trade price intelligence, detecting price dispersion between aggregators, and understanding consensus pricing — all without any execution risk or on-chain state changes. Prefer this over calling each DEX aggregator API separately when you want normalized output and explicit provider limitation disclosures in a single call.

## Known failure modes

- Unsupported token pair returns validation error (token_in must differ from token_out)
- token or chain not in supported enum returns 400-level error
- amount_in of zero or negative value rejected
- one or both upstream aggregators (1inch, KyberSwap) may be unavailable, reducing quote coverage
- slippage_bps outside 0–10000 range rejected
- network congestion on Base may cause stale or slow upstream quotes

## How this service works

Compare read-only Base swap quotes from 1inch and KyberSwap, returning normalized comparable output, consensus, dispersion, quote evidence, and explicit provider limitations without executing a swap.

## Output

Returns normalized, comparable swap quotes from 1inch and KyberSwap on Base, including a consensus price, price dispersion metric, raw quote evidence from each provider, and explicit notes on provider limitations. No trade is executed.
