Retrieve transaction data for a given block on Base via x402-paid crypto data intelligence endpoint.
What it does
This x402-gated endpoint, operated by Erudite Intelligence LLC, accepts a POST request containing a transaction hash and chain identifier and returns transaction data for the Base blockchain. It is part of the EruditePay Bridge ecosystem, which serves as an x402 payment facilitator supporting 20 blockchains.
The endpoint costs 0.01 USDC per call (10,000 base units of USDC on Base, network eip155:8453) or equivalently 0.01 USDT on Tron. Payment is handled via the x402 protocol (v2), with Coinbase CDP as the facilitator for the Base payment path. The provider describes the endpoint's purpose as "Crypto data intelligence."
The request body takes a JSON object with two fields: `hash` (a transaction hash string) and `chain` (a blockchain network identifier, e.g. "base"). The response returns a JSON object with a `success` boolean and a `data` object. Documentation beyond the x402 challenge metadata and the landing page is sparse — the /docs path returns a 404, and no OpenAPI spec is available. The exact structure of the returned `data` object is not documented in the probe material.
Capabilities
Use cases
- —Querying transaction details for a specific block or transaction hash on the Base blockchain
- —Building blockchain analytics dashboards that need per-transaction data
- —Automated on-chain monitoring agents that pay per query via x402
Fit
Best for
- —Agents or applications that need Base blockchain transaction data with micropayment access
- —x402-native workflows where crypto-settled API calls are preferred
- —Developers already integrated with the EruditePay Bridge facilitator
Not for
- —Users needing free or high-volume blockchain data (public RPC nodes or Etherscan-style APIs may be cheaper)
- —Querying blockchains other than Base (this specific endpoint is Base-only)
- —Users who need detailed API documentation before integrating (docs are currently sparse)
Quick start
curl -X POST https://bridge.eruditepay.com/v1/base/block/transactions \
-H "Content-Type: application/json" \
-H "X-PAYMENT: <x402-payment-header>" \
-d '{"hash": "0xabc...def", "chain": "base"}'Example
Request
{
"hash": "0x0000000000000000000000000000000000000000000000000000000000000000",
"chain": "base"
}Response
{
"data": {},
"success": true
}Endpoint
Quality
The x402 challenge is live and well-formed with clear pricing and schema metadata. However, there is no OpenAPI spec, the /docs path returns 404, and the output data structure is only shown as an empty placeholder object. The endpoint's exact capabilities must be inferred from the sparse bazaar extension metadata.
Warnings
- —No OpenAPI specification available
- —Documentation endpoint (/docs) returns 404
- —Output data structure is undocumented — the example only shows an empty object
- —The endpoint description 'Crypto data intelligence' is vague and the exact returned fields are unknown
