Token chart analytics for Base chain tokens, paid per-call via x402 in USDC or USDT.
What it does
This endpoint provides crypto token chart data on the Base network (eip155:8453). You send a POST request with a token contract address and receive chart/analytics data in return. The endpoint is gated by the x402 payment protocol (version 2), requiring a per-call micropayment of $0.01 (10,000 base units of USDC on Base or USDT on Tron) before the response is served.
The service is operated by Erudite Intelligence LLC, which also runs the EruditePay x402 Bridge facilitator. Payment can be settled through Coinbase CDP's x402 facilitator on Base (USDC) or directly on Tron (USDT). The endpoint accepts a JSON body with a single field — `token` — which takes a token contract address or symbol. The response is JSON with a `success` boolean and a `data` object, though the exact structure of the chart data is not documented beyond the example stub `{"success": true, "data": {}}`.
Documentation is sparse: there is no OpenAPI spec, no dedicated docs page (the /docs path returns a 404), and the only schema available is the inline Bazaar extension embedded in the 402 challenge. The endpoint is live and responds with a valid x402 v2 challenge, but the lack of detailed output documentation means consumers should expect to discover the response shape empirically.

Quality
The endpoint is live and returns a valid x402 v2 challenge with clear pricing and payment options. However, documentation is very sparse — no OpenAPI spec, no docs page, and the output schema is only a stub example with an empty data object. The actual chart data structure is unknown.
Warnings
- —No OpenAPI or dedicated documentation available; /docs returns 404
- —Output example is a stub — the actual shape of the 'data' object in the response is undocumented
- —Description says 'Crypto data intelligence' but specifics of what chart data is returned are unclear
- —Only tested via probe; actual paid response content is unverified
