Real-time HBAR token price data via x402 micropayment on Base network for $0.02/request.
What it does
This endpoint returns the current price of the HBAR (Hedera) 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 pay-per-call APIs offered at lowpaymentfee.com, spanning data analytics, AI/ML inference, finance/Web3 market data, and utility services. All endpoints on the platform share the same $0.02 per-request pricing model and settle payments in USDC on the Base L2 network. The x402 challenge confirms the endpoint is live, accepting payments to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout.
Documentation on the site is extremely sparse — the docs, pricing, and API pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI schema, no example request/response payloads, and no description of the response format beyond the stated mimeType of application/json. The actual fields returned in the HBAR price response are unknown and must be discovered by making a paid call.

Quality
The x402 challenge is live and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no documented request/response format, and all documentation pages return only a wallet-connect prompt. The actual response payload structure is entirely unknown.
Warnings
- —No API documentation available — docs, pricing, and API pages all render only 'Connect wallet' with no technical content.
- —Response schema for the HBAR price endpoint is undocumented; field names and structure are unknown.
- —No example requests or responses are provided anywhere on the site.
- —The site lists many endpoint categories (AI, analytics, utilities) but this specific /tokens/HBAR/price path is not listed on the homepage — it may be an unlisted or experimental endpoint.
