Agent budget planning for tool calls
“I'm building an agent that uses the x402 diagnostics tools — can you fetch the MCP tool prices from openclawproductions so I can estimate how much USDC my workflow will spend?”
Verifying x402 payment gate on tool endpoint
“Can you check the MCP tool price catalog on the openclawproductions x402 endpoint and confirm what payment is required to access each paid SKU?”
Technical details
Endpoint
GEThttps://openclawproductions.com/api/v1/mcptoolprices?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to discover the per-call USDC cost of specific MCP tool SKUs on the openclawproductions x402 platform before committing to paid calls; ideal for agent cost-planning workflows or auditing x402 payment gate behavior with EIP-3009 extras
Side effects
- HTTP 402 returned if payment not included — response contains EIP-3009 extras with payment instructions
- Invalid HTTP method returns error — only GET, HEAD, DELETE, POST are accepted
- Missing required 'type' or 'method' fields in input returns validation error
- Facilitator other than OpenX402 will not process payment, resulting in 402
