Tools (4)
🟢roundwatch.service_info
Return the live RoundWatch network, x402 service contract, USDC asset, price, limits, and documentation links. Read-only and free.
Input Schema
{
"type": "object",
"properties": {},
"additionalProperties": false
}🟢roundwatch.prepare_watch(idempotencyKey, expectedSender, expectedReceiver, atomicAmount, invoiceNote)
Validate one expected future Algorand USDC payment and return the exact RoundWatch HTTP/x402 request to create a durable watch. This tool does not settle the x402 payment and does not create the watch by itself.
Input Schema
{
"type": "object",
"properties": {
"idempotencyKey": {
"type": "string",
"minLength": 8,
"maxLength": 128,
"description": "Stable key that identifies this watch request and prevents duplicates."
},
"expectedSender": {
"type": "string",
"minLength": 58,
"maxLength": 58,
"description": "Checksum-valid nonzero Algorand address expected to send the future payment. The Algorand zero address is rejected for new watch creation."
},
"expectedReceiver": {
"type": "string",
"minLength": 58,
"maxLength": 58,
"description": "Checksum-valid Algorand address expected to receive the future payment."
},
"atomicAmount": {
"type": "string",
"pattern": "^[1-9]\\d*$",
"description": "Exact watched USDC amount in atomic units. Algorand USDC uses 6 decimals."
},

"type": "string",
"minLength": 1,

],
"additionalProperties": false
}🟢roundwatch.prepare_recovery(idempotencyKey, expectedSender, expectedReceiver, atomicAmount, invoiceNote, ...)
Validate and return the exact free HTTP request used to recover an existing watch after a paid create may have succeeded but the caller lost the returned watchId. Confirmed-settlement watches remain recoverable even after terminal expiry or post-activation indeterminate completion. This tool never signs, pays, or retries the paid create.
Input Schema
{
"type": "object",
"properties": {
"idempotencyKey": {
"type": "string",
"minLength": 8,
"maxLength": 128,

"description": "The exact original expected future-payment sender."
},
"expectedReceiver": {
"type": "string",
"minLength": 58,
"maxLength": 58,
"description": "The exact original expected future-payment receiver."
},
"atomicAmount": {
"type": "string",

"description": "The exact original watched USDC amount in atomic units."
},
"invoiceNote": {
"type": "string",
"minLength": 1,

"atomicAmount",
"servicePayer"
],
"additionalProperties": false
}🟢roundwatch.get_watch(watchId)
Read the durable state and any verified on-chain evidence for an existing RoundWatch watch ID. Read-only and free.
Input Schema
{
"type": "object",
"properties": {
"watchId": {
"type": "string",
