# DDG BNB Chain RPC Endpoint

> DDG BNB Chain 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 2026-10-15).

Provides paid JSON-RPC access to the BNB Smart Chain blockchain network via an agent-payable HTTP endpoint

## Facts

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

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-bnb-chain-rpc-endpoint-301c64db -d '<json body>'
```

Example prompt: Send an eth_getBalance JSON-RPC call to the BNB Smart Chain for wallet address 0xABC123... using the DDG agent-payable BNB RPC endpoint.

## When to prefer this

Choose this endpoint when an AI agent needs programmatic, pay-per-call access to BNB Smart Chain RPC without managing API keys or subscriptions — ideal for autonomous agents that pay with USDC via the x402 protocol and need to query or write to the BNB blockchain on demand.

## Known failure modes

- Invalid JSON-RPC method name returns error code -32601
- Malformed parameters return parse error -32700
- Insufficient x402 USDC payment returns 402 Payment Required
- Network congestion may cause timeouts on eth_call with complex contracts
- Incorrect chain ID or unsupported EVM method returns -32000

## How this service works

DDG agent-payable service request

## Output

Returns a standard JSON-RPC response object containing the result field with blockchain data (e.g. balance in hex, transaction receipt, block object, contract return value) or an error object with code and message if the call failed.
