Tools (3)

🟢 Read-only🟡 Write🔴 Delete⚪ Unknown
🟢get_tip_terms

Read free optional tip terms. Discovery never authorizes spending. No wallet or account required.

Input Schema

{
  "type": "object",
  "properties": {},
  "required": [],
  "additionalProperties": false
}
⚪prepare_tip_quote(amount, maxAmountUSD, ownerAuthorized, idempotencyKey)

Reserve an UNPAID optional tip quote only with owner permission and budget. Requires a locally generated private capability in the Authorization header. Persist it and the idempotency key first. This tool never signs or pays.

Input Schema

{
  "type": "object",
  "properties": {
    "amount": {
      "type": "string",
      "maxLength": 79,
      "description": "USDC decimal string, up to six decimals. Never use floating point."
    },
    "maxAmountUSD": {
      "type": "string",
      "maxLength": 79,
      "description": "USDC decimal string, up to six decimals. Never use floating point."
    },
    "ownerAuthorized": {
      "type": "boolean",
      "const": true
    },
    "idempotencyKey": {
      "type": "string",

  },
  "required": [
    "amount",
    "maxAmountUSD",
    "ownerAuthorized",
    "idempotencyKey"
  ],
  "additionalProperties": false
}
🟢get_tip_receipt(jobId, includeResult)

Read existing private job status or finalized contribution receipt using its original Authorization header. Never creates or retries a payment. includeResult=true requests the result; pending/error is not confirmation.

Input Schema

{
  "type": "object",
  "properties": {
    "jobId": {
      "type": "string",
      "pattern": "^agent_[a-f0-9]{48}$"
    },
    "includeResult": {
      "type": "boolean"
    }
