Get token price data on Base via x402-paid POST request for $0.01 per call.
What it does
This endpoint, hosted by Erudite Intelligence LLC on their EruditePay x402 Bridge, provides crypto token price data for tokens on the Base network. It accepts a POST request with a JSON body containing a token address or symbol and returns price information. The endpoint is described as "Crypto data intelligence" in its x402 challenge.
Payment is required via the x402 protocol (HTTP 402 challenge). The endpoint accepts two payment options: USDC on Base (eip155:8453) at 10,000 base units ($0.01) or USDT on Tron (tron:728126428) at 10,000 base units ($0.01). Payment is facilitated through the Coinbase CDP x402 facilitator for the Base option. The maximum payment timeout is 300 seconds for both options.
Documentation is sparse — the provider's /docs path returns a 404, and the Bazaar schema embedded in the x402 challenge provides only a minimal example with an empty data object in the output. The input schema indicates the body should contain a "token" field described as "Token address or symbol." The broader EruditePay Bridge platform supports 20 blockchains and is registered as a FinCEN MSB (BSA ID 31000324258137). However, specific documentation for this token price endpoint — including supported tokens, response field definitions, and rate limits — is not available from the crawled material.

Quality
The endpoint is live (402 challenge captured) with a clear payment schema and input specification, but documentation is effectively absent — /docs returns 404, the output example contains an empty data object, and there is no description of response fields, supported tokens, or rate limits.
Warnings
- —No dedicated documentation available; /docs returns 404
- —Output example in Bazaar schema shows empty data object — actual response structure is unknown
- —Supported token set and response fields are not documented
- —Provider description says 'Crypto data intelligence' but specifics of what price data is returned are unclear
