CAIP-2 Chain ID Parser
x402
CAIP-2 Chain ID Parser is a paid API for AI agents from api.delx.ai, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

How this service works
Parse CAIP-2 chain identifiers into namespace and reference parts. Call when normalizing multi-chain IDs from agent configs or wallets. Returns namespace, reference, and raw caip2 as deterministic JSON for $0.001 USDC via x402 on Base. First-party local math only—no RPC, live market feed, API keys, storage, or mediagen. Advisory only; the caller owns capital, risk, and production controls.
Output
Returns a deterministic JSON object containing the namespace (e.g. 'eip155'), the reference (e.g. '1'), and the original raw caip2 string as provided. No external calls are made — the result is computed locally from string parsing logic.
Example use cases
Normalizing wallet chain IDs
“I'm getting chain identifiers like 'eip155:137' and 'cosmos:cosmoshub-4' from different wallets — can you parse each one into namespace and reference so I can standardize them in my agent config?”
Agent cross-chain routing setup
“My agent needs to route transactions based on chain namespace. Parse 'solana:mainnet' into its namespace and reference components so I can use them to pick the right RPC endpoint.”
Validating CAIP-2 format from user input
“A user submitted 'bip122:000000000019d6689c085ae165831e93' as their chain ID — can you parse it into namespace and reference to confirm it's a valid CAIP-2 structure?”
Technical details
Endpoint
POSThttps://api.delx.ai/api/v1/x402/caip2-parseWhen to prefer
Use this endpoint when you need a lightweight, deterministic, zero-dependency way to decompose CAIP-2 chain identifiers into namespace and reference — especially in agent pipelines normalizing multi-chain configs or wallet data. Prefer it over custom string-splitting logic when you want a consistent, paid-gated microservice contract with predictable JSON output. Not suitable if you need live chain data, RPC calls, or chain validation against a registry.
Side effects
- Malformed CAIP-2 string (missing colon separator) returns an error or unexpected output
- Empty string input may return null or error fields
- Non-CAIP-2 strings (e.g. plain chain names) may not parse correctly
- Payment failure via x402 prevents the call from completing
