Batch token price lookup on Base via x402 micropayment — $0.01 per call in USDC or USDT.
What it does
This x402-enabled endpoint returns batch token price data for tokens on the Base network. You POST a JSON body containing a token address (or symbol), and receive price intelligence in response. Each call costs $0.01 (10,000 base units of USDC on Base or USDT on Tron, both 6-decimal stablecoins).
The endpoint is operated by Erudite Intelligence LLC, described on their landing page as a FinCEN MSB-registered entity (BSA ID 31000324258137). Payment is facilitated through the x402 v2 protocol and can be settled either on Base (USDC via Coinbase CDP facilitator) or on Tron (USDT). The response format is JSON with a top-level `success` boolean and a `data` object, though the exact structure of the price data within `data` is not documented beyond the example stub.
Documentation is sparse — the provider's /docs path returns a 404, and the Bazaar schema embedded in the 402 challenge provides only a minimal example with an empty `data` object. The endpoint name suggests batch capability ("prices-batch"), but the schema example shows a single `token` field, so it is unclear whether an array of tokens can be submitted in one request. Use with the understanding that the response schema is not fully specified.

Quality
The endpoint is live and returns a valid x402 v2 challenge with clear pricing ($0.01 per call). However, documentation is effectively absent — /docs returns 404, the Bazaar schema example shows an empty data object, and there is no OpenAPI spec. The actual response structure and batch semantics must be inferred from the endpoint name alone.
Warnings
- —No documentation available — /docs returns 404 and no OpenAPI spec was found
- —Response schema example contains only an empty data object; actual price data structure is unknown
- —Unclear whether the endpoint accepts multiple tokens in a single batch request despite the 'prices-batch' name
- —The Bazaar schema shows a single 'token' field but the endpoint name implies batch capability — ambiguous
