Pay-per-call EVM JSON-RPC access to 60+ Conduit-hosted rollup networks via MPP session payments.
What it does
Conduit Nodes provides EVM-compatible JSON-RPC endpoints for over 60 blockchain networks hosted on the Conduit rollup infrastructure. Networks span mainnets and testnets including Zora, Mode, Plume, Katana (Polygon), BOB, Orderly, Gravity, Superseed, Ancient8, Aevo, Derive (Lyra), Phala, Metal, Corn, Lit Chain, Zama, Tempo, and many more.
Each network is exposed as a separate sub-path under `https://mpp.conduit.xyz/:network` and accepts standard Ethereum JSON-RPC POST requests. Payment is handled via the MPP (Micropayment Protocol) with Tempo L2 session-based settlement. Every network charges 50 base units of pathUSD (6 decimals), which equals $0.00005 per request. The suggested session deposit is $0.50, covering roughly 10,000 calls. The payment intent is "session", meaning callers open a streaming payment channel rather than paying per individual HTTP round-trip.
The endpoint serves as a drop-in replacement for any standard EVM JSON-RPC provider (eth_blockNumber, eth_call, eth_getBalance, etc.) but requires an MPP-compatible client to negotiate the 402 payment challenge before receiving responses. Documentation is referenced at docs.conduit.xyz/rpc-nodes/getting-started/agent-skills.
Capabilities
Use cases
- —AI agents querying on-chain state (balances, contract reads) across multiple rollups without API keys
- —Automated trading bots reading Aevo, Derive, or Orderly chain data with per-call micropayments
- —Multi-chain indexers or analytics pipelines that need low-cost RPC access to 60+ networks
- —Developers testing smart contracts on various testnets (Mode Sepolia, Plume Testnet, Zora Sepolia, etc.)
- —Wallet backends resolving transaction data across Conduit-hosted L2s
Fit
Best for
- —Agents needing keyless, pay-as-you-go RPC access to many EVM chains
- —Low-volume or bursty workloads where a subscription is overkill
- —Multi-chain applications spanning Conduit-hosted rollups
- —Programmatic access from MPP-compatible clients
Not for
- —High-throughput indexing requiring dedicated/private nodes with guaranteed rate limits
- —Non-EVM chains (Solana, Cosmos, etc.)
- —Callers without an MPP/Tempo-compatible payment client
Quick start
# Open an MPP session on the Zora mainnet endpoint, then call eth_blockNumber
curl -X POST https://mpp.conduit.xyz/zora-mainnet-0/ \
-H 'Content-Type: application/json' \
-d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'Example
Request
{
"id": 1,
"method": "eth_blockNumber",
"params": [],
"jsonrpc": "2.0"
}Response
{
"id": 1,
"result": "0x1a2b3c",
"jsonrpc": "2.0"
}Endpoint
Quality
Full OpenAPI spec with 55+ network paths and consistent x-payment-info metadata. Payment terms (amount, decimals, intent, method) are clear and uniform. However, the probe returned 404 on HEAD/GET (expected since these are POST-only JSON-RPC endpoints), and no detailed API documentation or response schemas were crawled beyond the welcome message. The referenced docs URL was not fetched.
Warnings
- —Probe HEAD/GET returned 404 because all paths are POST-only; the endpoint is live for POST requests as confirmed by the OpenAPI spec.
- —No detailed response schema is provided in the OpenAPI spec beyond '200: Successful response'.
- —Documentation at docs.conduit.xyz/rpc-nodes/getting-started/agent-skills was referenced but not crawled; actual docs content is unverified.
- —The currency token address 0x20C000000000000000000000b9537d11c60E8b50 is assumed to be pathUSD on Tempo L2 based on context; this is not independently verified.
