IOTA token data via x402 micropayment on Base — $0.02 per request, no API key needed.
What it does
This endpoint at lowpaymentfee.com returns IOTA token information via a pay-per-call x402 model settled in USDC on the Base network. The specific resource `/api/v1/tokens/IOTA` sits within a broader platform that offers data & analytics, AI/ML inference, finance & Web3 data, and infrastructure utility endpoints — all priced at $0.02 per request.
The x402 challenge confirms the endpoint is live and accepts POST requests. Payment is made via the x402 exact scheme, requiring up to 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) sent to the provider's address on Base. There are no API keys, no rate limits, and no signup required — callers simply attach an X-PAYMENT header with a valid payment proof.
Documentation beyond the landing page is extremely sparse; the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available. The endpoint likely returns JSON (mimeType is application/json) with IOTA token data, but the exact fields are unknown.

Quality
The endpoint is confirmed live via a valid 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a landing page, and no example payloads. The actual data returned is entirely unknown, making this effectively a stub listing.
