What it does

EruditePay x402 Facilitator exposes 353 pay-per-call blockchain analytics endpoints accessible via the x402 micropayment protocol. The specific endpoint listed here (`/paid-resource-mainnet`) is a mainnet test resource that proves x402 payment verification works on Base mainnet. It costs $0.01 per call in USDC on Base (eip155:8453) or USDT on Tron.

The broader API suite covers Base and Tron chains extensively, with additional Bitcoin, XRP, and Kaspa payment verification endpoints. Capabilities include: wallet portfolios and balances, token prices and OHLCV history, DEX quotes and trades (Uniswap V3, Aerodrome, SunSwap), whale tracking, stablecoin analytics, NFT metadata, DeFi TVL and yield data, token security audits (honeypot/rug-pull scoring via GoPlus), sanctions checks (OFAC SDN), MEV sandwich detection, cross-chain bridge quotes (via deBridge), exchange flow monitoring, smart money analysis, gas/energy price oracles with forecasts, and a merchant payment link system. Prices range from $0.001 to $0.10 per call depending on endpoint complexity. Payment is accepted in USDC on Base or USDT on Tron, with a facilitator at bridge.eruditepay.com. Bundle tokens are available for 60-second unlimited access at $0.10 (gas oracle) or $0.50 (all intel endpoints).

Use cases

  • —AI agents querying real-time token prices, wallet balances, and DeFi yields across Base and Tron without API keys
  • —Automated compliance checks: sanctions screening and token rug-pull risk scoring before executing trades
  • —Monitoring whale movements, exchange inflows/outflows, and large DEX swaps for trading signals
  • —Cross-chain bridge quoting and stablecoin spread analysis between Base USDC and Tron USDT
  • —Building pay-per-call crypto dashboards with no subscription using x402 micropayments

Fit

Best for

  • —Autonomous agents needing keyless, pay-per-call blockchain data access
  • —Multi-chain analytics covering both Base (EVM) and Tron ecosystems
  • —Token security auditing: honeypot detection, tax analysis, and holder concentration
  • —Real-time gas/energy price monitoring with forecasting across chains

Not for

  • —High-frequency trading requiring sub-second latency (pay-per-call overhead)
  • —Chains not covered: Solana, Avalanche, Polygon, Arbitrum analytics are not available despite the facilitator supporting 20 chains for settlement
  • —Users who need free-tier access or traditional API key authentication

Quality

0.82/ 1.00

Full OpenAPI 3.1 schema with 353 endpoints, clear x402 payment challenge captured and live (402 returned), pricing documented per-endpoint in human-readable USD. Docked slightly because response schemas are not detailed (only 200/402 status codes, no field-level output schemas) and no actual 200 response examples from real data endpoints were captured.

Warnings

  • —Response schemas lack field-level detail — only status codes documented, no output object definitions for data endpoints
  • —The /paid-resource-mainnet endpoint is a test/proof-of-concept resource, not a data endpoint itself
  • —Claims of 20 supported settlement chains and Bitcoin/XRP/Kaspa analytics endpoints could not be independently verified beyond the OpenAPI spec
  • —No crawled documentation pages were accessible (/docs, /api, /pricing all returned 404)
