# x402.dailyelo.com Pre-flight Safety Bundle

> x402.dailyelo.com Pre-flight Safety Bundle is a paid API for AI agents from x402.dailyelo.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-13).

Bundles signature-intent decode, live malicious-address + look-alike check, and standing-approval drainer audit into a single paid call before an agent signs or sends a transaction

## 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 x402-dailyelo-com-pre-flight-safety-bundle-aa1c6a36 -d '<json body>'
```

Example prompt: Before I send this transaction, run the full pre-flight safety bundle on it — decode the calldata 0xa9059cbb000000000000000000000000abcdef1234..., check if the recipient 0xAbCdEf1234567890... is malicious or looks like any of my trusted addresses [0xDEAD...beef, 0xFACE...cafe], and audit these standing approvals: USDC approved to spender 0x1234... for 1000000000.

## When to prefer this

Use this endpoint when an agent needs to perform multiple pre-send safety checks (signature decode + recipient threat check + approval audit) and wants to avoid 3-4 separate paid round-trips. Ideal for automated agent pipelines that need deterministic, LLM-free safety signals before signing any EVM transaction. Prefer over individual sibling endpoints when latency and cost efficiency matter and all three checks are needed simultaneously.

## Known failure modes

- Invalid or malformed 0x calldata returns a decode error for that sub-check while others proceed
- Recipient address not 0x-prefixed or wrong length returns address validation error
- Payment not included or insufficient USDC causes 402 rejection before any checks run
- typedData object missing required EIP-712 fields (domain/primaryType/message) causes decode failure
- Empty approvals array skips approval audit sub-check silently
- known_addresses containing malformed entries may cause look-alike sub-check to error or skip

## How this service works

One-call pre-transaction guard for agents: bundle the transaction you're about to sign/send and get every applicable safety check in a single payment — signature-intent decode, live threat-DB + address-poisoning look-alike on the recipient, and a drainer audit of standing approvals. By design no combined safe/danger verdict is emitted; each sub-check's flags & evidence come back verbatim so your agent decides. Replaces 4 separate 402 round-trips with 1. Deterministic, no LLM.

## Output

Returns per-sub-check results verbatim: decoded human-readable intent from calldata or EIP-712 data, threat-DB hit flags and evidence for the recipient, address-poisoning look-alike similarity scores against known counterparties, and drainer risk flags with evidence for each standing approval — no combined verdict, agent decides based on raw flags.
