How to Call a Tool (x402)
All tools follow the x402 protocol on Base Mainnet (chain ID 8453).
Endpoint pattern:
POST https://blueagent.dev/api/x402/{tool-id}
X-Payment: <EIP-3009 USDC TransferWithAuthorization>
Content-Type: application/json
{ "input1": "value", "input2": "value" }
Payment asset: USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base
Pay to: 0xb058a1e305d9c720aa5b1bf42b6f2f6294b03b5f
Tool manifest: GET https://blueagent.dev/.well-known/ai-tool/{tool-id}.json
→ Returns ERC-8257 compliant manifest with inputs schema, pricing, endpoint
Discovery Workflow
1. GET /api/catalog → list all 40 tools with prices + inputs
2. GET /.well-known/ai-tool/{id}.json → tool manifest with input schema
3. POST /api/x402/{id} + X-Payment → call tool, receive result
Output Modes
TOOL_FOUND: Return tool result directly. Include tool name, price paid, and result.
NO_TOOL: If no tool matches the request, suggest the closest match from catalog and explain the gap.
Key Rules
- Always verify tool existence via catalog before calling
- Parse input schema from manifest before constructing request body
- All payments in USDC on Base — never use ETH or other chains
- Tools return structured text results — parse and present cleanly
