How this service works
Look up supported blockchain network metadata and chain IDs for $0.001 USDC. Static first-party registry only—no live RPC, balances, blocks, receipts, gas, or contract reads. Call when you need this bounded result without an API key or subscription. Returns machine-readable JSON via x402 on Base or Solana. Limitation: results cover only the supplied input or one bounded public endpoint at request time; callers must verify before acting.
Output
Returns metadata about one or more supported blockchain networks, including chain ID, network name, and aliases. If a specific network name or chain ID is provided, returns the matching entry; otherwise returns the full registry of supported networks.
Example use cases
Resolve network name to chain ID
“What is the EVM chain ID for Arbitrum One? Look it up in the Delx chain network registry.”
List all supported blockchain networks
“Can you pull the full list of supported blockchain networks and their chain IDs from the Delx registry?”
Validate chain ID before transaction
“I have chain ID 8453 — can you look up what blockchain network that corresponds to in the Delx chain registry?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/chain-network-info?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to resolve a human-readable blockchain network name to its EVM chain ID, or vice versa, without needing live on-chain data such as balances, gas prices, or block info. Prefer this over full RPC providers when the task is purely metadata lookup — it is cheaper, faster, and deterministic.
Side effects
- Unknown network name or alias returns an error or empty result
- Chain ID not in the supported registry returns no match
- Invalid chain_id type (non-integer) causes a validation error
- Both network and chain_id omitted returns full registry rather than a specific entry
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| network | string | Optional network name or alias; omit to return the full registry. |
| chain_id | integer | Optional EVM decimal chain ID; pass this instead of network. |
