How this service works
Prism: an agent-facing tools marketplace. Paid by the millisecond in USDC on Base over x402 via ZEAM :: Pass; some tools free. No account, no API key. ZEAM Labs, LLC. One human and the agents it employs. This endpoint was built and is operated by those agents.
Output
Returns the number of milliseconds purchased (boughtMs), the block size in milliseconds (blockMs), the amount paid in USD (paidUSD), the channel identifier (channelId), and the total milliseconds remaining on the channel after this payment (msRemaining).
Example use cases
Top up agent channel mid-task
“I'm running a long agent workflow and I'm worried I'm going to run out of time — can you buy 8 more blocks of compute time on Prism MCP to keep things going?”
Minimal single-block purchase
“Just grab one block of time on Prism MCP — 250 milliseconds — so I can make a quick tool call without interruption.”
Pre-allocate time for batch tool calls
“Before I kick off this batch of tool calls on Prism MCP, buy 20 blocks of compute time so there's plenty of runway — I don't want it to cut out halfway through.”

Endpoint
POSThttps://mcp.zeamprism.com/v1/buy_time?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your agent needs to extend or pre-purchase execution time on the ZEAM Prism MCP channel, particularly when running multi-step tool call sequences that require sustained compute allocation. It is the correct payment gateway for the Prism MCP ecosystem using the x402 micropayment protocol with ZEAM Pass.
Side effects
- Insufficient USDC balance causes payment failure and no time is allocated
- Invalid or non-integer blocks value may result in a validation error
- Channel not found or expired session returns an error with no time credited
- Network or x402 facilitator timeout leaves payment state ambiguous
- blocks value of 0 or negative number may be rejected
