How this service works
Use when your client cannot sign an x402 payment per call (most MCP clients): one payment buys prepaid credit ($5, $20 = $22 credit, $50 = $60) and returns an API key. Send it as X-API-Key on any paid route or MCP tool; each call costs its x402 price and failed calls are refunded. With your key in X-API-Key it tops that key up.
Output
Returns an API key that can be used as X-API-Key on any paid Market Intelligence API route or MCP tool. The key carries a prepaid credit balance equal to the purchased pack amount ($5 for this endpoint). Each subsequent paid call deducts its x402 price from the balance, and failed calls are refunded.
Example use cases
MCP client API key provisioning
“My MCP client can't sign x402 payments for each call — buy the $5 credit pack from Market Intelligence API and return the API key so I can attach it to all my market data requests.”
Low-commitment market data trial
“I want to try the Market Intelligence API's crypto and stock signals without committing a lot — get me the $5 prepaid starter pack and give me the API key.”
Top up existing Market Intelligence key
“I already have a Market Intelligence API key and I want to add more credits to it — go ahead and purchase the $5 credit top-up using my key in the X-API-Key header.”
Technical details
Endpoint
GEThttps://api.marketintelligenceapi.com/api/v1/credits/buy/5?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your client (e.g. an MCP client or AI agent) cannot sign x402 per-call payments natively and needs a simpler API-key-based access model. Also use it when you want a low-cost entry point ($5) to trial the Market Intelligence API before committing to larger packs. If you already have an API key, this endpoint can top it up with additional credits.

- Insufficient USDC balance in paying wallet — transaction fails
- Network or gateway error during payment processing — retry required
