# Amoraw CAIP Chain & Asset Canonicalizer

> Amoraw CAIP Chain & Asset Canonicalizer is a paid API for AI agents from amoraw.xyz, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

Canonicalizes a CAIP-2/CAIP-19 or legacy network string and returns normalized chain info, native currency, USDC asset details, x402 scheme support, and registry metadata.

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 amoraw-caip-chain-asset-canonicalizer-eef1e44c -d '<json body>'
```

Example prompt: Can you canonicalize the network string 'ethereum' or 'eip155:1' for me and tell me what the recognized chain name is, its native currency, the USDC asset address with decimals, and which x402 payment schemes it supports?

## When to prefer this

Choose this endpoint when you need to normalize or validate blockchain network identifiers — especially CAIP-2/CAIP-19 strings or legacy names — and need authoritative USDC asset details and x402 scheme support for cross-chain payment workflows. Prefer this over manual lookups or hardcoded mappings when accuracy of decimals, asset addresses, and x402 compatibility matters for your payment or DeFi integration.

## Known failure modes

- Unrecognized network string returns error or empty recognized status
- Malformed CAIP-2/CAIP-19 input may return validation error
- Chain exists in registry but has no x402 support, returning empty schemes array
- Registry version mismatch may cause stale data responses
- Payment failure (x402) if USDC balance is insufficient for the $0.001 call fee

## How this service works

Canonicalize a CAIP-2/CAIP-19 or legacy network string and return the recognized chain, native currency, reviewed USDC asset and decimals, supported x402 schemes, supported-versus-recognized status and registry version.

## Output

Returns a JSON object containing the canonical chain identifier, native currency details, the reviewed USDC asset address with decimal precision, list of supported x402 payment schemes, a flag indicating whether the chain is fully supported versus merely recognized, and the current registry version used for the lookup.
