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 indicating whether the chain ID was found, the canonical network name (e.g. 'base'), the numeric chain ID string, a flag indicating whether live RPC data is included (always false — static table only), the table size, a schema identifier, and an advisory note that this is a static lookup not live chain state.
Example use cases
Resolving chain ID before token transfer
“I need to confirm what network chain ID 8453 refers to before I send a USDC transaction — can you look it up?”
Validating user-supplied chain ID in dApp
“A user entered chain ID 137 in my app — can you check what network that maps to so I can confirm it's correct before proceeding?”
Agent mapping network slug to chain ID
“I have the network slug 'base' and I need its numeric chain ID — can you resolve that for me using the chain ID lookup?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/chain-id-lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, cheap, no-signup resolution of a blockchain chain ID to a human-readable network name (or vice versa) and don't need live RPC state. Prefer it over querying an RPC node directly when you only need the name-to-ID mapping. Ideal for agents performing pre-flight validation before on-chain transactions or routing logic that depends on knowing which network a chain ID refers to.
Side effects
- Unknown chain ID or slug returns found: false with no network data
- Malformed or non-numeric chain_id string may yield no match
- Static table may not include newly launched chains or testnets
- No RPC or live chain tip data is ever returned — only static mapping
