Pay-per-call BTC price data via x402 on Base (USDC) or Tron (USDT) for $0.01 per request.
What it does
The btc-price endpoint from Erudite Intelligence LLC returns cryptocurrency price data for a given token address or symbol. It is an x402-gated POST endpoint described as "Crypto data intelligence." Each call costs $0.01 (10,000 base units of USDC on Base or USDT on Tron, both 6-decimal stablecoins). The endpoint accepts a JSON body with a `token` field (a token address or symbol) and returns a JSON object with a `success` boolean and a `data` object.
The endpoint is live and returns a proper x402 v2 challenge when called without payment. It supports two payment rails: USDC on Base (eip155:8453) settled via the Coinbase CDP x402 facilitator, and Tether USDT on Tron (tron:728126428). The payment timeout is 300 seconds. The provider, Erudite Intelligence LLC, also operates the EruditePay x402 Bridge facilitator service, which supports 20 blockchains.
Documentation is sparse — the endpoint's output schema only shows a generic `{"success": true, "data": {}}` example with no detail on what fields appear inside `data`. The provider's docs URL (docs.eruditepay.com) was not reachable during crawl, and the /docs path on the bridge returns a 404. Despite the endpoint name suggesting BTC-specific pricing, the schema accepts an arbitrary token address, implying it may serve price data for multiple tokens. The exact data fields returned remain unknown.
Capabilities
Use cases
- —Fetching current BTC or token prices in an automated trading agent

- —Building a portfolio tracker that pays per price lookup with no subscription
Fit
Best for
- —Agents that need on-demand crypto price data without API key management
- —Low-volume or bursty price lookups where per-call pricing is cheaper than a subscription
- —x402-native applications already using USDC on Base or USDT on Tron
Not for
- —High-frequency trading requiring sub-second latency and bulk pricing (per-call cost adds up)
- —Users who need detailed OHLCV or historical price data (output schema is unknown)
- —Applications that cannot pay with USDC on Base or USDT on Tron

Quality
The endpoint is live and returns a valid x402 v2 challenge with clear pricing ($0.01/call). However, the output schema is essentially empty (generic success + empty data object), no real documentation is available, and the actual response fields are unknown. The bazaar schema provides minimal input/output detail.
Warnings
- —Output data structure is unknown — the example only shows an empty `data` object
- —Provider documentation at docs.eruditepay.com was not reachable during crawl
- —Despite the endpoint name 'btc-price', the schema accepts arbitrary token addresses — actual scope is unclear
