Real-time IOTA token price data via x402 micropayment on Base network, $0.02 per request.
What it does
This endpoint returns the current price of the IOTA token, accessible through the x402 payment protocol on the Base network. Each request costs $0.02 (20,000 base units of USDC with 6 decimals) and requires no API keys, rate limits, or upfront commitments — you simply attach an x402 payment header to your POST request.
The endpoint is part of a broader suite of APIs offered by lowpaymentfee.com, which spans data analytics, AI/ML inference, finance/Web3 market data, and utility services, all priced uniformly at $0.02 per call. The specific endpoint at `/api/v1/tokens/IOTA/price` falls under the Finance & Web3 category and is designed to deliver token price information in JSON format.
Payment is settled in USDC (contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) on the Base L2 network using the x402 "exact" scheme. The endpoint was confirmed live, returning a proper 402 challenge with x402Version 1. Documentation beyond the landing page is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no additional technical detail or response schema information.
Capabilities
Use cases

Fit
Best for
- —Developers needing quick, keyless access to IOTA price data
- —AI agents that can settle x402 micropayments autonomously on Base

Quality
The endpoint is confirmed live with a valid 402 challenge and clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no documented request/response format, and the docs/pricing/API pages are all empty beyond a wallet-connect prompt. The response structure must be entirely inferred.
Warnings
- —No response schema or example response documented anywhere
- —Docs, pricing, and API pages render only 'Connect wallet' with no technical content
- —The specific /api/v1/tokens/IOTA/price path is not listed on the landing page — only generic finance endpoints are shown, so this endpoint's existence is confirmed only by the 402 probe
- —No information on data source, update frequency, or accuracy of the IOTA price feed
