Get the current price of IMX token via a pay-per-call x402 endpoint on Base.
What it does
This endpoint returns the current price of the IMX (Immutable X) token. It is part of a broader suite of APIs hosted at lowpaymentfee.com that cover data analytics, AI/ML inference, finance, crypto, and utility services — all payable per request via the x402 protocol on the Base network using USDC.
The specific endpoint `/api/v1/tokens/IMX/price` accepts POST requests and returns JSON. Each call costs $0.02 (20,000 base units of USDC on Base, which has 6 decimals). Payment is handled inline via the x402 `X-PAYMENT` header — no API keys, accounts, or rate limits are required. The x402 challenge confirms the endpoint is live, accepting payments to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a maximum timeout of 300 seconds.
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 example request/response payloads, and no description of the response schema. The endpoint appears to be part of a pattern (`/api/v1/tokens/{symbol}/price`) but this is inferred, not documented.

Fit
Best for
- —Developers needing quick, keyless access to IMX token pricing
- —AI agents that can settle x402 payments autonomously on Base
- —Applications requiring low-friction, pay-as-you-go crypto price data
Not for
- —High-frequency trading requiring sub-second latency guarantees (no SLA documented)

Quality
The x402 challenge is live and confirms pricing and payment details, but there is no OpenAPI spec, no documented request/response schema, no example payloads, and the docs pages are empty stubs. The endpoint's actual behavior must be entirely inferred from its URL pattern and the landing page description.
Warnings
- —No OpenAPI or schema documentation available — response format is unknown
- —All documentation pages (/docs, /api, /pricing, /README) return only a 'Connect wallet' prompt with no content
- —No example request or response payloads are available anywhere in the crawl
- —The broader lowpaymentfee.com platform lists many endpoints but provides no technical detail for any of them
- —The specific /api/v1/tokens/IMX/price path is not listed on the landing page; it may be an undocumented or dynamically-routed endpoint
