# DDG Unichain RPC Endpoint

> DDG Unichain RPC Endpoint is a paid API for AI agents from agents.daedalusdevelopmentgroup.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-28).

Provides a paid JSON-RPC gateway to the Unichain blockchain network for AI agents via x402 micropayments

## Facts

- Endpoint: POST https://agents.daedalusdevelopmentgroup.com/v1/chains/unichain/rpc?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_7WJC_khAOo-AZpeEFvtRc

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 ddg-unichain-rpc-endpoint-14e610fc -d '<json body>'
```

Example prompt: Make a JSON-RPC POST call to the Unichain network to get the current block number — use eth_blockNumber as the method with no params.

## When to prefer this

Choose this endpoint when your agent needs to interact with the Unichain blockchain specifically (not Ethereum mainnet or other L2s) via standard JSON-RPC, and you want a pay-per-call model using x402 USDC micropayments rather than managing an API key subscription. Ideal for agents that need occasional, metered on-chain reads or transaction submissions on Unichain.

## Known failure modes

- Payment failure — x402 micropayment not processed, returns 402 status
- Invalid RPC method — unrecognized eth_ method returns JSON-RPC error code -32601
- Malformed request body — missing required fields returns 400 or JSON-RPC parse error
- Network congestion — Unichain node timeout or 503 response
- Insufficient funds — submitted transaction reverts on-chain

## How this service works

Machine-payable DDG services for AI agents. Current public live payment rails are x402 multi-chain USDC and direct-crypto auto/manual for public receiving-address families. MPP/Stripe/Tempo is installed but pending live provider env plus penny-settlement proof before any MPP-live advertisement. DDG sells bounded artifacts/results, not raw provider account access.

## Output

Returns a standard JSON-RPC response object from the Unichain node, including a result field containing the requested chain data (block number, balance, transaction hash, contract return value, etc.) or an error object with code and message if the call fails.
