Pay-per-call BCH token data via x402 on Base, settled in USDC at $0.02/request.
What it does
This endpoint at lowpaymentfee.com provides BCH (Bitcoin Cash) token information through a pay-per-request x402 protocol. The specific endpoint `/api/v1/tokens/BCH` is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3 data, and infrastructure utility APIs — all priced uniformly at $0.02 per request and settled in USDC on the Base network.
Payment is handled via the x402 exact-payment scheme: callers attach an X-PAYMENT header with a signed USDC payment of up to 20,000 base units (i.e., $0.02, since USDC uses 6 decimals) to the payTo address `0x1A2B…85F3`. No API keys, rate limits, or upfront commitments are required — each request is independently paid and authenticated on-chain.
Documentation on the site is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no example payloads available. The endpoint is confirmed live (returns a proper 402 challenge), but the actual response format for a paid request to `/api/v1/tokens/BCH` must be inferred — it likely returns JSON with BCH token data such as price, market cap, or metadata, but this is unconfirmed.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming it works. However, there is zero documentation on request parameters, response schema, or what data is actually returned. The docs/pricing/README pages are all blank beyond a wallet-connect prompt. This is effectively a stub listing with only the payment challenge as evidence.
Warnings
- —No API documentation available — docs, pricing, and README pages all show only 'Connect wallet'
- —No OpenAPI spec or request/response schema provided
- —Actual response payload for /api/v1/tokens/BCH is unknown — token data content is inferred
- —The platform lists many endpoints across categories but none have documented schemas
