Fetch Tron block data by number via x402 micropayment (USDC on Base or USDT on Tron)
What it does
This endpoint, operated by Erudite Intelligence LLC, returns Tron blockchain block data when given a block number. It is an x402-gated POST endpoint at https://bridge.eruditepay.com/v1/tron/block/by-number. Callers must include a valid x402 payment header to access the data. The endpoint accepts payment in two ways: USDC on Base (EIP-155:8453) or USDT on Tron (tron:728126428), both priced at 10,000 base units per call — which equals $0.01 USD given 6-decimal stablecoins.
The request body is JSON and, based on the Bazaar schema embedded in the x402 challenge, expects properties such as a blockchain identifier and a Tron address. However, the endpoint path says "block/by-number," suggesting the body should contain a block number — the example body in the schema shows a `chain` and `address` field, which may be a generic template rather than the actual input for this specific route. The response format is JSON with a `success` boolean and a `data` object.
The provider, EruditePay, operates an x402 payment facilitator bridge supporting 20 blockchains. The facilitator is registered as a FinCEN MSB (BSA ID 31000324258137) and is non-custodial. The endpoint returned a proper 402 challenge on probe, confirming it is live. Documentation at docs.eruditepay.com is referenced on the landing page but the /docs path on the bridge itself returns a 404, so detailed API documentation for this specific data endpoint is not available from the crawl.
Capabilities
Use cases
- —Retrieve Tron block details by block number for chain analytics
- —Build block explorers or indexers that need on-demand Tron block data
- —Integrate Tron block queries into agent workflows with micropayment access
- —Verify on-chain Tron activity by fetching specific blocks
Fit
Best for
- —Developers needing pay-per-call Tron block data without running a full node
- —AI agents that need programmatic access to Tron blockchain blocks
- —Applications requiring low-cost ($0.01/call) Tron block lookups
Not for
- —High-volume bulk block ingestion (per-call cost adds up quickly)
- —Querying non-Tron blockchains (this endpoint is Tron-specific)
- —Users who need free or subscription-based blockchain data access

}Endpoint
Quality
The endpoint is live (402 challenge confirmed) with clear pricing ($0.01 per call in USDC or USDT). However, the Bazaar schema example body (chain + address) does not match the endpoint path (block/by-number), suggesting a generic or mismatched template. No dedicated API docs were reachable from the crawl, and the output example is an empty data object, providing no insight into actual response structure.
Warnings
- —The Bazaar schema example body shows 'chain' and 'address' fields, which may not match the actual expected input for a block-by-number endpoint — the real request body format is uncertain.
- —docs.eruditepay.com is referenced but not crawled; the /docs path on the bridge returns 404.
- —The output example contains an empty 'data' object, so the actual response structure is unknown.
