Cross-chain bridge history lookup via x402-paid POST endpoint
What it does
The `/v1/bridge/history` endpoint on EruditePay's x402 Bridge returns cross-chain bridge transaction history filtered by source and destination blockchain. It accepts a JSON POST body with `sourceChain` and `destChain` parameters and returns structured data about bridge operations between those networks. The endpoint is described as providing "Crypto data intelligence."
Payment is handled via the x402 protocol (HTTP 402 challenge). The endpoint accepts payment in USDC on Base (eip155:8453) or USDT on Tron (tron:728126428), both at 10,000 base units — which equals $0.01 per request (6-decimal stablecoins). The facilitator is Coinbase CDP for the Base/USDC option. The provider is Erudite Intelligence LLC, a FinCEN-registered MSB (BSA ID 31000324258137).
The parent Bridge service supports 20 blockchains and implements the x402 v2 facilitator specification with verify and settle endpoints. Documentation at docs.eruditepay.com is referenced but the /docs path on the bridge itself returns a 404. The output schema example is sparse — `{"success": true, "data": {}}` — so the exact shape of the history response is not fully documented. The endpoint is live and returning a valid x402 challenge.
Capabilities
Use cases
- —Querying historical bridge transactions between two specific blockchains
- —Monitoring cross-chain fund flows for analytics or compliance
- —Building dashboards that track bridge activity across networks
- —Auditing bridge operations between Base, Tron, and other supported chains
Fit
Best for
- —Agents needing programmatic access to cross-chain bridge history
- —Crypto analytics pipelines requiring bridge transaction data
- —Compliance workflows tracking cross-chain fund movements
Not for
- —Initiating or executing bridge transfers (this is read-only history)
- —Free or high-volume bulk data extraction (each call costs $0.01)
- —Non-crypto use cases with no blockchain component

}Response
{
"data": {},
"success": true
}Endpoint
Quality
The endpoint is live with a valid x402 challenge and has a basic input schema with example, but the output schema is essentially empty (data: {}), documentation links return 404, and the actual response structure is undocumented. Pricing is clear at $0.01/call.
Warnings
- —Output schema example is a stub — actual response shape for bridge history data is unknown
- —docs.eruditepay.com is referenced but /docs on the bridge returns endpoint_not_found
- —The exact fields returned in the 'data' object are not documented anywhere in available materials
- —Only two chain values ('base', 'tron') are shown in examples; full set of valid sourceChain/destChain values is unspecified
