🟢search_apis(query, verified_only, limit)
Free-text search across the live catalogue. Matches listing name, description, category and provider name. Returns settlement-verified listings only unless verified_only is false. Free and read-only; spends nothing.
Input Schema
{
"type": "object",
"properties": {
"query": {
"type": "string",
"description": "What you are looking for, e.g. \"uk property\" or \"sanctions screening\"."
},
"verified_only": {
"type": "boolean",
"default": true,
"description": "Restrict to settlement-verified listings. Default true."
},

"type": "integer",
"minimum": 1,
"maximum": 100,
"default": 20

"additionalProperties": false
}🟢list_apis(category, verified_only, limit)
Browse the live catalogue, optionally filtered to one category. Omit category for everything. Returns settlement-verified listings only unless verified_only is false. Free and read-only; spends nothing.
Input Schema
{
"type": "object",
"properties": {
"category": {

}
},
"additionalProperties": false
}🟢get_api(id)
Fetch a single live listing by its id or slug, including base_url, price range, network and verification state. Also returns a reliability object: score (0 to 100 or null), band (strong, established, thin, caution or unscored) and computed_at. Reliability is a running score from paid verifications, health history and payTo integrity, not a star rating and not a guarantee; unscored means it has not been computed for that listing yet. Method: https://payapi.market/how-an-agent-finds-payapi. Returns the listing whether or not it is verified, and reports payment_verified honestly. Free and read-only; spends nothing.
Input Schema
{
"type": "object",
"properties": {
"id": {
"type": "string",
"description": "Listing uuid or slug, as returned by search_apis or list_apis."
}
},
"required": [
"id"
],
"additionalProperties": false
