Pay-per-call ENS token data endpoint on Base via x402, $0.02/request in USDC.
What it does
This endpoint at lowpaymentfee.com provides token data for ENS (Ethereum Name Service) via a pay-per-request x402 protocol. It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure APIs—all priced at $0.02 per request with no API keys, no rate limits, and no commitments required.
The specific endpoint `/api/v1/tokens/ENS` accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The x402 challenge specifies a maxAmountRequired of 20000 base units, which equals $0.02 (USDC uses 6 decimals). The payment timeout is 300 seconds.
The platform advertises itself as a simple, keyless API marketplace where you pay only for what you use. Documentation and detailed schema information are sparse—the docs, pricing, and API pages all appear to require a wallet connection to view content. The exact response format for the ENS token endpoint is not documented in available materials, so the output structure must be inferred as token-related data (likely price, metadata, or market information for ENS).
Capabilities
Use cases
- —Fetching current ENS token data or pricing information on demand
- —Building dashboards or bots that need ENS market data without managing API keys
- —Agent-driven workflows that pay per call for crypto token information
- —Integrating ENS token data into DeFi applications
Fit
Best for
- —Developers needing keyless, on-demand ENS token data
- —AI agents that can settle micropayments on Base
- —Low-volume or sporadic token data lookups where subscriptions are wasteful
Not for
- —High-frequency trading requiring sub-second latency guarantees (no SLA documented)
- —Users who cannot transact in USDC on Base network
- —Comprehensive ENS domain resolution (this is token data, not name resolution)

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing. However, there is no OpenAPI schema, no documented request/response format, and the docs pages are gated behind wallet connection, leaving the actual data returned by this endpoint unknown.
