Pay-per-call JSON-RPC access to the Tempo blockchain via MPP micropayments.
What it does
Tempo RPC is a micropayment-gated JSON-RPC endpoint for the Tempo blockchain. It is designed to provide standard Ethereum-compatible JSON-RPC calls (such as eth_blockNumber, eth_getBalance, eth_call, etc.) at a cost of $0.001 per request, settled via the MPP (Micropayment Protocol) on Tempo's L2 infrastructure.
The endpoint is intended to be called via POST with a JSON-RPC body, which is the standard method for Ethereum-style RPC nodes. The probe attempted HEAD and GET requests, both of which returned 404 — this is expected behavior for a JSON-RPC endpoint that only accepts POST requests with a properly formatted JSON body. The MPP payment challenge would typically be returned in response to a POST request without valid payment credentials.
Because the probe did not attempt a POST method and all crawled pages returned "Not Found," there is limited information available beyond the Bazaar listing metadata. The endpoint likely requires a JSON-RPC POST with an accompanying MPP payment header to function. No OpenAPI schema, documentation pages, or additional technical details were found during the crawl.
Capabilities
Use cases
- —Querying Tempo blockchain state (block numbers, balances, transaction receipts)
- —Submitting transactions to the Tempo L2 network
- —Building dApps that need on-demand RPC access without monthly subscriptions
- —Programmatic smart contract reads via eth_call on Tempo
Fit
Best for
- —Agents or bots needing occasional Tempo blockchain queries at low per-call cost
- —Developers prototyping on Tempo L2 without committing to an RPC subscription
- —Pay-as-you-go blockchain data access settled via micropayments
Not for
- —High-throughput applications needing thousands of RPC calls per second (per-call pricing may add up)
- —Users needing RPC access to non-Tempo blockchains (Ethereum mainnet, Polygon, etc.)

}Endpoint
Quality
The probe only attempted HEAD and GET, which return 404 on a POST-only JSON-RPC endpoint, so liveness could not be confirmed. No documentation, schema, or crawled content was found. All details are inferred from the Bazaar listing title/description and standard JSON-RPC conventions.
Warnings
- —Endpoint returned 404 on HEAD and GET; likely requires POST with JSON-RPC body, but MPP 402 challenge was not captured
- —No documentation or OpenAPI schema found at any crawled path
- —Pricing ($0.001/call) is taken from the listing title only and could not be independently verified
- —Liveness unconfirmed — the probe did not attempt POST, which is the expected method for JSON-RPC
