Delx Chain Id Lookup
x402
Delx Chain Id Lookup is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.003/call, status unknown (last checked 2026-09-13).
Looks up a static mapping from a numeric chain ID or network slug to its canonical network name, with no live RPC call required.

How this service works
Look up a static chain id to network name table without live RPC — call when mapping a static chain id to a network name (no tip). Use for chain input hygiene without live RPC—adjacent to OneSource-class small chain reads, but static/local only so rights and margin stay clear. Returns deterministic machine-readable JSON for $0.003 USDC via x402 on Base. Execution is first-party, local-only, stateless, and memory-only with no paid upstream, no input retention, and no claim of live chain tip, web…
Output
Returns a deterministic, machine-readable JSON object containing the canonical network name and associated metadata for the given chain ID or network slug. The response is static and local — no live chain tip or RPC state is included.
Example use cases
Validate chain ID before transaction
“Before I send this transaction, can you confirm what blockchain network chain ID 137 refers to? I want to make sure I'm targeting the right network.”
Display network name in UI
“I have a list of chain IDs from user wallets — can you look up the human-readable network name for chain ID 42161 so I can display it properly in the dashboard?”
Sanitize chain input in pipeline
“I'm processing some raw chain IDs coming in from an API — can you resolve chain ID 10 to its official network name so I can normalize the data before storing it?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/chain-id-lookupWhen to prefer
Choose this endpoint when you need a fast, deterministic, no-RPC mapping from a chain ID to a network name for input validation or display purposes. Prefer it over live RPC calls when you only need the name and do not require current chain tip data. It is ideal for sanitizing user-supplied chain IDs in pipelines where latency and cost matter and live connectivity is unnecessary.
Side effects
- Unknown or unsupported chain ID returns an error or empty result
- Invalid input format (non-numeric, unrecognized slug) may return a validation error
- Payment failure via x402 on Base prevents execution
- The static table may not include newly launched or obscure chains
