extensions/v1

BuildBazaarExtensionFromDiscoveryInfo builds a v2 bazaar extension from extracted v1 discovery info.

V1 had no formal schema validation, so the synthesized schema is permissive.

BuildV1CatalogExtensions normalizes v1 catalog extension payloads to v2 bazaar format.

Preserves non-bazaar extensions from the payment payload. Replaces legacy outputSchema entries with a synthesized bazaar extension.

ExtractDiscoveryInfoV1 extracts discovery info from v1 PaymentRequirements and transforms to v2 format

In v1, the discovery information is stored in the outputSchema field, which contains both input (endpoint shape) and output (response schema) information.

This function makes smart assumptions to normalize v1 data into v2 DiscoveryInfo format:

• For GET/HEAD/DELETE: Looks for queryParams, query, or params fields
• For POST/PUT/PATCH: Looks for bodyFields, body, or data fields and normalizes bodyType
• Extracts optional headers if present

Args:

• paymentRequirements: V1 payment requirements (as a map or struct with outputSchema field)

Returns:

• Discovery info in v2 format if present and valid, or nil if not discoverable

Example:

requirements := map[string]interface{}{
    "outputSchema": map[string]interface{}{
        "input": map[string]interface{}{
            "type": "http",
            "method": "GET",
            "discoverable": true,
            "queryParams": map[string]interface{}{"query": "string"},
        },
        "output": map[string]interface{}{"type": "object"},
    },
}

info, err := v1.ExtractDiscoveryInfoV1(requirements)
if info != nil {
    fmt.Printf("Endpoint method: %v\n", info.Input)
}

ExtractResourceMetadataV1 extracts resource metadata from v1 PaymentRequirements

In v1, resource information is embedded directly in the payment requirements rather than in a separate resource object.

Args:

• paymentRequirements: V1 payment requirements

Returns:

• Resource metadata (url, description, mimeType)

Example:

metadata := v1.ExtractResourceMetadataV1(requirements)
fmt.Printf("Resource URL: %s\n", metadata["url"])

IsDiscoverableV1 checks if v1 PaymentRequirements contains discoverable information

Args:

• paymentRequirements: V1 payment requirements

Returns:

• True if the requirements contain valid discovery info

Example:

if v1.IsDiscoverableV1(requirements) {
    info, _ := v1.ExtractDiscoveryInfoV1(requirements)
    // Catalog info in Bazaar
}
