# Delx Commerce — Chain Network Info Lookup

> Delx Commerce — Chain Network Info Lookup is a paid API for AI agents from commerce.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).

Returns static registry metadata for blockchain networks by name or EVM chain ID, including CAIP-2 identifier, chain family, and display name.

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 delx-commerce-chain-network-info-lookup-ae330a18 -d '<json body>'
```

Example prompt: What is the CAIP-2 identifier and chain family for Base mainnet — can you look it up by network name 'base'?

## When to prefer this

Use this endpoint when an agent needs to resolve a human-readable network name or numeric EVM chain ID to canonical blockchain metadata (CAIP-2, chain family, display name) without needing live chain state. Prefer over RPC calls or on-chain queries when only static registry info is needed. Ideal for pre-flight validation, transaction routing, or populating chain selectors in agent workflows.

## Known failure modes

- Unknown network name or alias returns empty networks array
- Invalid chain_id format or out-of-range integer returns validation error
- Both network and chain_id omitted returns full registry (not an error, but may be unexpected for callers expecting a single result)
- Non-EVM chains may not be in the registry, resulting in empty result

## How this service works

Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.

## Output

Returns a JSON object with the registry schema version, source, data mode, freshness note, and an array of matched network entries — each containing CAIP-2 ID, status, network slug, chain ID, chain family, and display name. Also notes what data is explicitly not included (balances, blocks, gas, etc.) and how the match was made.
